Advances In High Performance Multijunction III-V Solar Cells

Abstract

This paper provides a discussion of current progress in III-V multijunction solar cells. A review of tandem cell principles is first presented, followed by a review of current research results reported by several active groups. Structures yielding efficiencies in the range of 25% to 35% are discussed. A brief discussion of the attainable efficiency in a three-junction approach is presented.
