At the Photovoltaics Beyond Conventional Silicon Europe Conference, Vince Arancio, technical specialist -- DuPont MCM, presented new research findings on "Advanced Screen Printable Thin Film Photovoltaic Front-Side Silver Conductor Compositions"
Abstract: Advanced Screen Printable Thin Film PV Front-Side Silver Conductor Compositions
A series of new Thin-Film PV front-side silver conductor compositions have 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 screenprinting manufacturing operations and are easily processed at 140°C for 5-10 minutes. Reliability studies on these conductors have shown very good stability out to 1000 hours of storage at 85°C/85% RH as well as 1000 hours exposure to thermal cycling. 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.
