Hello, welcome to NeoScribe.

There’s an energy source so powerful that it can potentially provide more energy in just one hour than the ENTIRE human civilization uses in a year.
And that energy source has a virtually unlimited supply, lasting for BILLIONS of years.
We’re talking about the Sun, and it’s going to be a major part of how we power modern life in the future.
So, welcome to the first video of a new series that aims to explore the future of energy, beginning with Solar Power. (Dramatic Music Moment)

Harnessing the power of the sun starts with the Photoelectric effect principle, which was first observed by Heinrich Hertz in 1887.
The photoelectric effect is the phenomenon that occurs when light strikes certain materials, releasing a current of electrons.
And that is fundamentally how solar or photovoltaic cells work.
But the challenge that scientists have faced over the years has been improving the efficiency of energy harnessed from given amount sunlight.
You see, when light strikes PV cells, most of the energy is lost by reflection or as heat.
Take the first solar cell, created by Charles Fritts in 1883.
It was made out of Selenium with a thin coating of gold and only converted between 1-2% of the sun’s energy.
It wasn’t until the 1950’s that scientists at Bell Labs discovered that Silicon was more effective than Selenium.

And this allowed for PV cells with 6% efficiency.
But the cost of production at the time made them only practical for special uses such as on Spacecraft.
From here, scientists were ready to face the 2nd challenge of lowering the cost of production.
And this surprisingly brings us to the Exxon Corporation which funded research in the 1970s that led to PV cells being made from cheaper materials.
This dropped the price of PV cells from $480 per watt all the way to almost $100 per watt adjusted for inflation.
Today, most modern silicon solar panels are either monocrystalline or polycrystalline.
Monocrystalline PV cells are recognized by its dark color and trimmed corners.
Each cell is a thin slice of a long cylinder of silicon.
Then polycrystalline have a blueish color and are made out of molten silicon poured into very thin films.
The top commercial PV cells today have efficiencies of around 20%.
On top of that, the cost per watt is expected to drop to just 22 cents by 2022!
With the high efficiencies and low production costs, is Solar Power is now the fastest growing energy source, making up two-thirds of net new capacity globally.
Global photovoltaic power capacity broke 1 GW for the first time in the year 2000.
Today global PV power capacity is well over 500 GW accounting for around 1% of the world’s electricity generation.
And according to a recent report out of Norway, the solar electricity generation will grow 65 times by 2050.
There’s so much room for usage to grow as well as so much room for the technology to improve.
Back in November, the Institute for Solar Energy Research in Hamelin, Germany developed a solar cell with an efficiency of 26.1%.
This was achieved using Surface Passivation.
The technique involves two thin layers of oxidized and crystallized silicon called passivating contacts, that are sandwiched between the solar cell and its metal contact.
The contacts add efficiency by healing broken atomic bonds on the silicon surface along with preventing electric charges from being trapped in the system.

    When will episode 2 come out.

  8. MsJeffreyF on September 11, 2020 at 3:43 pm

    The "which country is China spying on" joke was rather uncalled for

  9. YK Chan on September 11, 2020 at 3:44 pm

    Time marker 9:55. It this fair a fair statement that molten salt delay cycling down of electric generation after dusk is a plus in CSP system? and holding back the minus that it may take nearly as much delay to cycle up from dawn? Is that statement came from scientists or lobbyist?

  10. Michael Burke on September 11, 2020 at 3:45 pm

    Ohhhhh pooooh. I’m sure darwin could teach the birds to avoid heliostats in a few decades? No? Well mebbe some hundreds of years, after all a moth changed it’s coloring in decades…

    Best video, this format is a winner

  12. Mike C on September 11, 2020 at 3:47 pm

    If we could link all the world together we could use solar with out large dangerous commercial batteries.

  13. Glascoe Bowie on September 11, 2020 at 3:49 pm

    The repeat of the age of solar energy after these secret societies finish settling up there human pyramid Jacob’s latter to make every body else dependent on them,4th of JULY is a ritual.

    Hello my friend.
    What do you use to make your videos? I am making videos with renderforest. But it has not enough funktions

  15. Xtroverted Hermit on September 11, 2020 at 3:50 pm

    how potent will solar power be in this on coming grand solar minimum.

  16. David Heller on September 11, 2020 at 3:52 pm

  17. Kenneth D. on September 11, 2020 at 3:52 pm

    I hope your next video covers energy conversion options and storage opportunities. Please discuss Chemical vs Mechanical energy storage, some arguments address scale expectations and peak energy consumption times as it relates to renewable resources.

  18. John Evans on September 11, 2020 at 3:52 pm

    I’m going to school to become a solar power technician and this video has given me hope for my industry and the planet. Thank you!

    all sounds great if u have 9 sun hours a day with no cloud rain etc still if the grid goes down u still have no power unless u pay for a off grid power wall if u can get insurance to cover it and councils have rules limits etc.

  30. HKspurs10 on September 11, 2020 at 4:06 pm

    what’s the cost and efficiency of CSP vs PV?

  31. Tharun Thangavel on September 11, 2020 at 4:06 pm

    No mention of perovskite solar cells!!?

    Nice bit of sinophobia there. China invests more into solar and renewables than any other country on Earth. They also publish more papers on solar power research. They also have the highest amount of patents. So why the fuck spout CIA talking points? Fucking brainwashed yanks.

  34. WINSTON SMITH on September 11, 2020 at 4:08 pm

    You said the Ever Present Sun.The sun is only out 10 hrs and 17 minutes today. I’ll stick with my coal powered electric plant..

    Insightful and valuable for humankind.

  37. YK Chan on September 11, 2020 at 4:09 pm

    For energy generation and storage means such as solar cell, wind mill, battery and others, is it necessary to conceive/consider each environmental and geopolitical impact/cost? Such as plotting a country in gaining cheap access of their resource instead of empowerment and fair trade? What about weight in environment impact of each product’s end-to-end cycle from mining, process waste, manufacturing waste, factory waste, end of life waste and renewal or dispose? Without each full cycle consideration to an act could it be as good as steal/rob first then deal/escape penalty later?

  38. sgtevmckay on September 11, 2020 at 4:10 pm

    Ooooooh…..ahhhhhhh……boink!

    This was all sounding great. The future was. Brite, solar was/is the way
    Prices falling quality and efficiency improving almost monthly.
    By the end of 2017 I was very excited for the new improvements that were to be released between February and May of 2018.

    Then tariffs kicked in!

    Prices on solar balanced or even went up in some cases.
    U.S. solar, instead of using this time to inovate and capitalize on the latest tech and improvements, maintained status quo manufacturing, refused to release next gen eqipment and raised their prices to be just below foreign offerings that were of similar quality.

    We are one year down the road….and still waiting for that promised next gen from last year. Still waiting on the 45 to 50 cents a watt on smaller solar systems, and still waiting for the Solar Industry to move forward.
    Right now, the tech is their, but no one sees a need to release it with the tariffs in play.

    Tariffs were supposed to dump up over 3 years and sunset in 5 years.
    This can not happen soon enough.

    But this seems to throw the whole 2022 mark in the dirt.

    Sincerely
    Disgruntled Solar Wanter

  39. Loupi l18 on September 11, 2020 at 4:10 pm

    Wait, is it true that the sun radiates in 1h what we consume in a whole year ?
    If so, that is totally dramatic.
    Indeed, 24*365 = 8760 years of human consumption generated in 1 solar year.
    BUT the Earth being located at 150 million km from the sun and assuming it as a 6300 km radius circle (so overestimating the amount of light being captured because of deeper atmosphere absorbtion near the poles), it covers a solid angle of 1.78864973e-9 steradian, which is equivalent to (1/7)E-7 % of the suns emissions that we can receive.
    It goes without saying that even by covering the whole Earth surface, we would still be living on fossile resources

  40. jigga jaw on September 11, 2020 at 4:13 pm

    But when will we see the solar panels at 10 cents per watt?

  41. Hyric89 on September 11, 2020 at 4:14 pm

    OPV solar cells made from oil. That’d be hilarious.

  42. Baqir Khan on September 11, 2020 at 4:15 pm

    Why u westerners thinks that technology belongs to ur father ajd that no one else is better enough to lead science. Do u think being white skinned u are some sort of godly wise people of another specie. U cant digest the fact of Chinas innovations u think they copy.. Common fellas every nation copied.. The muslim scientists copied and developed from greeks the westerned copied mislim golden era scientist and science shifted to west now china is copying the knowledge of science and the lead in science is again coming in asias hands..

  43. WinterHell on September 11, 2020 at 4:20 pm

    “Which country did China spy on? Just kidding… seriously, which country?” LOL!

  44. Horge El Rodrigo on September 11, 2020 at 4:25 pm

    There’s a serious possibility that Solar Cells can be contributing to the Global Warming Crisis. S.C.s reflect about 60% of light and heat back into the atmosphere; the more panels installed the warmer the atmosphere gets.

  45. Luis Erlacher on September 11, 2020 at 4:28 pm

    Saltwater batteryreactor fly with solar energy to university milky-way for spaceshutles and transport uranium to uranus and fly with Laser

  46. John Burns on September 11, 2020 at 4:28 pm

    Solar PV panels have hit just below 40%. …and rising.

  47. kai usernameisbetter on September 11, 2020 at 4:28 pm

    Fusion is the future

  48. Vivekh Anand on September 11, 2020 at 4:29 pm

    Are you from China Uncensored?

  49. Cindy Tepper on September 11, 2020 at 4:30 pm

    I live about 80 miles west of NYC. If we are lucky we get about 3 solar hours on average per day. Really a huge part of the country only gets like 3 hours or less per day. Now tell me again about how solar is going to supply energy for everything.

  50. Tom Kelly on September 11, 2020 at 4:32 pm

    There is another one that gets very very little press but is very promising! It is called Ocean Thermal Energy Convertion or OTEC. Heat that is captured by warm and deep tropical ocean water is used to boil a gas like propane or butane and then that gas is condensed by the colder bottom water. Turbines are turned by the boiling gas. Hawaii, Japan and India all have made these and the potential is far far greater then land based solar power since we have so much ocean to work with
