The Study of Materials Properties For Quantum Dot Solar Cell

Abstract

A quantum dot solar cell is a solar cell design that uses quantum dots as the absorbing photovoltaic material. Quantum dot (QD) solar cells have the potential to increase the maximum attainable thermodynamic conversion efficiency of solar photon conversion up to about 66% by utilizing hot photo generated carriers to produce higher photo voltages or higher photocurrents. The main advantage with quantum dots is the ability to tune the size of the dots for many applications. Their electronic characteristics are closely related to the size and shape of the individual crystals. In this work we have studied the Quantum dot solar cell properties of 5 different semiconductor materials such as( InAs, InSb, PbS, PbSe, PbTe) and which can captured all solar radiation spectrum. It is found that InSb semiconductor material QDs have the smallest size for Quantum dot solar cell spectrum.
