Abstract

Using measured device parameters from a monolithic three-terminal InP/GaInAs (0.75 eV) tandem concentrator solar cell, a numerical model has been constructed that calculates efficiency as a function of temperature and concentration ratio. The device measurements indicate that the series resistance in the InP top cell severely limits the maximum efficiency at high concentration ratios. Results from the model in which a single-junction InP concentrator solar cell that has a lower resistance by a factor of six was substituted for the top cell show that peak 20°C air mass zero (AM0) efficiencies should approach 30% at concentration ratios greater than 100. At 80°C, this tandem cell should exceed 24% AM0 efficiency.
