Title: Solar heating of GaAs nanowire solar cells

Abstract

We use a coupled thermal-optical approach to model the operating temperature rise in GaAs nanowire solar cells. Our findings show that despite more highly concentrated light absorption and lower thermal conductivity, the overall temperature rise in a nanowire structure is no higher than in a planar structure. Moreover, coating the nanowires with a transparent polymer can increase the radiative cooling power by 2.2 times, lowering the operating temperature by nearly 7 K.
