Abstract

This paper investigates which dopping concentration or layer thickness should be used to design practical GaInP/GaInAs/Ge triple-junction cells in order to optimize their performance. A rigorous model includes optical and electrical modules is developed to simulate the external quantumn efficiency, photocurrent and photovoltage of the GaInP/GaInAs/Ge tandem solar cells. It is found that cell efficiency strongly dependend on the top cell thickness and doping concentration at base and emitter layers. Proper structures of the tandem cell operating under AM0 ("air mass zero") illumination are suggested to obtain high efficiency.
