摘要

Abstract

The limitations imposed by low contact resistance

restricted polarization access

and tensile strain in bulk photovoltaic systems were mitigated by the engineering and optimization of edge semimetal contacts using Bi/Au. Improved bulk PV photocurrent and intriguing prospective applications are made possible by this effort.
