Silicon Heterojunction Solar Cells

"Silicon heterojunction solar cells----Understanding and optimization of a-Si PECVD deposition" is a summary of author's research work on silicon heterojunction solar cells at Institute of Energy Conversion, University of Delaware. The author's team is the first U.S. research group that demonstrates a >18% silicon heterojunction solar cell and the first team in worldwide that demonstrates an all back contact silicon heterojunction solar cell.
