"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.

Dong Xu is a member of technical staff in Twin Creeks Technologies. He is working on high efficiency silicon solar cells and modules with an emphasis on back end of line process. He is awarded M.S.E.E from Institute of Energy Conversion at University of Delaware after he finished B.S.E.E.in mainland China.
