Special Coating Increases Solar Cell Voltage 40%

Northwestern University (TGW) – Researchers at Northwestern University can increase solar cell voltage by approximately 40% and conversion efficiency by up to 5.6% by a special coating to the cell.

The coating covers the anode of the solar cell with a 5 to 10 nanometer thick smoother layer of nickel oxide. This material is an excellent conductor for extracting holes from the irradiated cell but, equally important, is an efficient "blocker" which prevents misdirected electrons from straying to the "wrong" electrode (the anode), which would compromise the cell energy conversion efficiency.

The process is cheap and non corrosive, the research team said.
