Abstract
This study aims to improve and evaluate the external quantum efficiency (EQE) of p-i-n GaAs solar cells. The current densities of minority carriers and the geometrical and physical cell parameters were calculated using the finite difference method. As a result, the EQE simulation findings are extremely close to the experimental data, and a maximum EQE of 57.26 %, with optimum layer thicknesses (µm) of p, i, and n are respectively 0.2,1,4, and n and p layers doping (cm-3 ) of 1020 cm-3 and 4 × 1017 cm-3 . The adding of p+-AlGaAs window layer increases the energy conversion efficiency (%) from 19.41 to 25.45.
期刊介绍：
Journal of Ovonic Research (JOR) appears with six issues per year and is open to the reviews, papers, short communications and breakings news inserted as Short Notes, in the field of ovonic (mainly chalcogenide) materials for memories, smart materials based on ovonic materials (combinations of various elements including chalcogenides), materials with nano-structures based on various alloys, as well as semiconducting materials and alloys based on amorphous silicon, germanium, carbon in their various nanostructured forms, either simple or doped/alloyed with hydrogen, fluorine, chlorine and other elements of high interest for applications in electronics and optoelectronics. Papers on minerals with possible applications in electronics and optoelectronics are encouraged.
