Hardly a day goes by without an announcement of another “breakthrough” in the labs of solar cell and solar panel researchers. From organic solar cells to multi-junction solar cells to black silicon to perovskites, there are many options beyond simple crystalline silicon solar cells that are exciting scientists in universities and research labs around the world. But what kind of a future do these competing options have? Will any of these new materials bring about a “next-generation” solar era ?
It’s all about price, of course. How cheaply can these various options produce electricity? How cheaply will they be able to produce electricity in 10 years?
