Abstract

Electroluminescence (EL) can provide a valuable insight into the performance of individual junctions in a triple junction cell designed for use in high concentration photovoltaic (HCPV) applications. It has the potential to be used in quality control in cell production as well as providing specific information about the performance of the cell´s emitter and metallisation scheme. This paper presents an EL examination of triple junction photovoltaic cells from four commercial vendors of (Al)InGaP/(In)GaAs/Ge based concentrator cells and analyses their suitability for use in a HCPV system.
