Researchers make unsuitable parts work as solar cells, could lead to cheaper panels

Engadget writes, Harnessing the power of the sun is a tricky business, but even the past few weeks have seen some interesting developments in the field. In this latest installment, researchers from the Lawrence Berkeley National Laboratory and the University of California have figured out a way of making solar cells from any semiconductor, potentially reducing the cost of their production. You see, efficient solar cells require semiconductors to be chemically modified for the current they produce to flow in one direction. The process uses expensive materials and only works with a few types of semiconductors,...
