Abstract

Quantum Well (QW) Photovoltaic Cells - third generation solar cells, were proposed in 1990 by the research group of Professor Keith Barnham, aiming at extending the spectral response and at increasing the photocurrent. This paper tackles some original aspects regarding the influence of the optical parameters of the quantum well solar cells, upon conversion efficiency, based on the modelling and simulation approach, as follows: • Refraction index modelling and simulation; • Reflectance modelling and simulation; • Absorption coefficient modelling; Evaluation of datasheet parameters of the multiple quantum well solar cells (MQW); our study is based on the hybrid model HM which allows computing of the levels whatsoever the form of the quantum wells..
