Abstract

A method, system and apparatus including a device cell having a top side, a bottom side and opposing side walls. A passivation layer is formed along the top side, the bottom side and opposing side walls of the device cell. The passivation layer serves to passivate the device cell and facilitate carrier collection around the device cell. An anti-reflective layer is formed over the passivation layer and an optical layer is formed on the top side of the device cell. The optical layer reflects light within the device cell. The apparatus may further include a reflective layer formed along the bottom side of the device cell, the reflective layer to reflect light internally within the device cell.

Method of fabricating high-efficiency Cu(In,Ga)(SeS).sub.2 thin films for solar cells

Patent Noufi, Rommel [Golden, CO]; Gabor, Andrew M [Boulder, CO]; Tuttle, John R [Denver, CO]; ...

A process for producing a slightly Cu-poor thin film of Cu(In,Ga)(Se,S).sub.2 comprises depositing a first layer of (In,Ga).sub.x (Se,S).sub.y followed by depositing just enough Cu+(Se,S) or Cu.sub.x (Se,S) to produce the desired slightly Cu-poor material. In a variation, most, but not all, (about 90 to 99%) of the (In,Ga).sub.x (Se,S).sub.y is deposited first, followed by deposition of all the Cu+(Se,S) or Cu.sub.x (Se,S) to go near stoichiometric, possibly or even preferably slightly Cu-rich, and then in turn followed by deposition of the remainder (about 1 to 10%) of the (In,Ga).sub.x (Se,S).sub.y to end with a slightly Cu-poor composition.
