✦ Synopsis
We present recent advances obtained at GSI in scaling-up multichamber fabrication of solar cells. We have successfully adopted the multichamber approach in the development of large-area compound curved semitransparent modules. For this application, a new semitransparent electrode was developed, together with an innovative three-dimensional laser patterning technique. A fully automated 1.5 MW annual production line with a "glass-inpanel-out" approach has been completed for the Government of India, and another 3 MW plant is presently under construction. GSI's research effort using its multichamber R&D system has achieved single-junction conversion efficiencies of 11.3% at low intrinsic layer deposition rates and of 9.7% at a rate of 18 A s -1.
