NIST researchers have shown that electron beam lithography and etching can produce quantum dots which can be shaped and positioned more reliably than dots made with conventional crystal growth methods.
LG Innotek and the University of Delaware's Institute of Energy Conversion (IEC) will explore the development of a high-voltage CIGS “superstrate” solar cell structure. Unlike most CIGS solar cell modules which require two pieces of glass, the superstrate cell will require only one sheet of glass, on the light-exposed side of the cell solar cell.
Researchers have created a triple junction solar cell using GaAsN grown using MOCVD. The key to making the multiband cell work is to make sure the intermediate band is isolated from the contacts where current is collected.
