Green solvents for a 17%-efficient organic solar cell

Scientists in Sweden and China developed a solution-based process to produce organic solar cells, demonstrating efficiencies better than 17%. The process utilizes paraxylene as a solvent, which the researchers claim is less toxic and more stable than others used to reach high organic solar cell efficiencies, and with more work could be scaled up to produce large area devices.Organic PV covers a range of different materials that have maintained plenty of interest from researchers, but not yet achieved the levels of performance that would be needed to attract commercial interest, save for a few ...
