Chinese researchers have taken what they say is a major step forward for the development of a new generation of solar cells.

Manufacturers have long used silicon to make solar panels because the material was the most efficient at converting sunlight into electricity.

But organic photovoltaics, made from carbon and plastic, promise a cheaper way of generating electricity.

This new study shows that organics can now be just as efficient as silicon. ...

What are organic solar cells?

The term organic relates to the fact that carbon-based materials are at the heart of these devices, rather than silicon. The square or rectangular solid solar panels that most of us are familiar with, require fixed installation points usually on roofs or in flat fields.

Organic photovoltaics (OPV) can be made of compounds that are dissolved in ink so they can be printed on thin rolls of plastic, they can bend or curve around structures or even be incorporated into clothing. ...

Commercial solar photovoltaics usually covert 15-22% of sunlight, with a world record for a silicon cell of 27.3% reached in this summer in the UK.

Organics have long lingered at around half this rate, but this year has seen some major leaps forward.

In April researchers were able to reach 15% in tests. Now this new study pushes that beyond 17% with the authors saying that up to 25% is possible.

This is important because according to estimates, with a 15% efficiency and a 20 year lifetime, organic solar cells could produce electricity at a cost of less than 7 cents per kilowatt-hour.

In 2017, the average cost of electricity in the US was 10.5 cents per kilowatt-hour, according to the US Energy Information Administration.

We all want to believe.

HAHAHA. At a cost less than 7 cents per kWh? Really? We're talking commodity price here people, then you have to add all of the other charges to get to your bundled rate. Which is what they are comparing it to at 10.5 cents / kWh. Which in CA is already 21 cents or $0.21/kWh for Tier 1 residential use, that is with a mix of renewables already factored in, but the majority of spinning generation is made at a commodity rate of 2.5-6 cents per kWh.




The Housing Trap
You're being set up to spend your life paying off a debt you don't need to take on, for a house that costs far more than it should. The conspirators are all around you, smiling to lure you in, carefully choosing their words and watching your reactions as they push your buttons, anxiously waiting for the moment when you sign the papers that will trap you and guarantee their payoff. Don't be just another victim of the housing market. Use this book to defend your freedom and defeat their schemes. You can win the game, but first you have to learn how to play it.
