Design for high efficiency full spectrum photovoltaics

Abstract

Advances in photovoltaics moved the advanced research frontiers towards concepts that can enable ultrahigh efficiency (η = 30-50% and beyond). Achievement of ultrahigh efficiencies requires addressing fundamental optical principles and full solar spectrum utilization. Making significant progress requires combining i) fundamental principles governing limits to solar conversion efficiency ii) materials with high radiative efficiency) and iii) new electromagnetic design concepts.
