Exploring Back Contact Technology to Increase CdS/CdTe Solar Cell Efficiency

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

The primary routes for increasing CdS/CdTe solar cell efficiency involve increasing free carrier density, reducing bulk and interface recombination, and/or reducing back contact barrier height. This paper focuses on the role of the back contact barrier in increasing cell efficiency. Measurement of barrier height and back surface recombination are outlined and three CdTe/MX/M back contact prototypes, each with particular strengths, are discussed to bring out important issues.
