METHOD FOR THIN FILM SILICON PHOTOVOLTAIC CELL PRODUCTION

摘要

This invention relates to a solar cell arrangement and to a process for manufacturing thin film silicon-based solar cells. It particular addresses the topic of reducing the active layer thicknesses significantly by advanced light trapping. The invention proposes a solar cell arrangement with an extent > 1.4 m2 in tandem configuration comprising an a-Si Cell (4) and a µc-Si cell (10), the absorber layer of the a-Si cell (4) having a thickness of 210nm ± 20 nm, the absorber layer of the µc-Si cell (10) having a thickness of 900 nm ± 200 nm.
