Lattice-matched hot carrier solar cell with energy selectivity integrated into hot carrier absorber

Abstract

We propose a technologically feasible concept of a hot carrier (HC) solar cell (SC) which fulfills the electronic, optical, and to some extent the phononic criteria required. The energy selective process of HCs is implemented into the hot carrier absorber (HCA). Its electronic properties are investigated by a Monte-Carlo code which simulates random deviations of structure thickness and a normal distribution of random elastic electron (e -) scattering. The structure can be grown epitaxially as a HC-SC test device. © 2012 The Japan Society of Applied Physics.
