Abstract :
A series of new Thin-Film PV front-side silver conductor compositions has been developed for CIGS and a-Si Thin-Film PV cells. These new conductors provide outstanding adhesion to various Transparent Conductive Oxides (TCO.´s) such as Indium Tin Oxide (ITO). Additionally, these front-side silvers exhibit very high conductivity and extremely low contact resistance to the TCO. They have been formulated for screen-printing manufacturing operations and are easily processed at 130°-180 C for 5-10 minutes in a manufacturing oven. Reliability studies on these conductors have shown very good stability out to 600 hours of storage at 85°C/85% RH. The details of the compositions and their properties as well as the typical construction of the Thin-Film cell using these front-side silvers will be discussed.
