BBC article: Organic Solar Cells
"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."

This doesn't look great, but we've only been at this Green Energy project for about 20 years. Think where we'll be after another 20 years.
