Princeton researchers led by electrical engineer Stephen Chou have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that ...

Careful selection of small-molecule materials provides solution-processed tandem organic solar cells with a boost in efficiency.

Perovskite solar cells have been limited by the use of relatively expensive organic compounds as hole-transporting materials. Here, Qin et al.use an inorganic hole conductor, CuSCN, in a lead ...
