Researchers from the Wuhan University of Technology in China have designed and synthesized a new non-fullerene acceptor for organic solar cells. One of their fabricated devices achieved the highest certified efficiency ever reported for single-junction organic solar cells.
Right, lower efficiency is offset by the fact that the cells require less resources to manufacture, so you can just make more of them with lower environmental impact. It’s also worth noting that China is pursuing a broad spectrum of options for energy production. It looks like nuclear will act as the backbone of the grid, and it will be supplemented by solar, wind, hydro, etc at local level.
