Introduction of the a-SiC:H/a-Si:H heterojunction solar cell and update on thin film Si:H solar modules

摘要

Hydrogenated a-Si:H, first reported by the late professor Walter Spear, has found an application in solar cells and, via tremendous R&D efforts, a series of industrial technologies have been developed to produce large area thin film Si solar modules. Thin film Si: H solar modules began production in 1999 and became a major industry due to environmental concerns. Our proposed solar module is now the global standards. In this paper, the history of thin film Si solar cell technologies are reviewed.
