Optical and thermal properties of In12Ga88N/GaN solar cells

In this work we investigate the optical and thermal properties of In
₁₂
Ga
₈₈
N/GaN photovoltaic devices. These devices show very good solar cell characteristics with peak external quantum efficiency of 63%, open circuit voltage of 1.7 V, and a fill factor of 76%. Thermal measurements show no reduction in output power with increasing temperature up to 87°C.
