Development of High-Efficiency Solar Cells on Silicon Web. Eighth Quarterly Progress Report, January 1-March 31, 1986

摘要

The major objective of this contract is to improve web base material with a goal of obtaining solar cell efficiencies in excess of 18% (AM1). Efforts in this program are directed toward identifying carrier loss mechanisms in web silicon, eliminating or reducing these mechanisms, designing a high-efficiency cell structure with the aid of numerical models, and fabricating high-efficiency web solar cells. Fabrication techniques must preserve or enhance carrier lifetime in the bulk of the cell and minimize recombination of carriers at the external surfaces. (ERA citation 11:035686)
