Quantum dot solar cells for future electric prospects - A small Review

Abstract

Owing to their versatile electro-optic properties semiconductor quantum dots (QDs) are gaining greater attention towards photovoltaic applications. Although hybrid solar cells, which are obtained by the blend of carbon-based and inorganic resources have the probable to attain higher energy conversion efficiencies, the current efficiencies are stumpy. Strategy aspects especially the electronic structure of the inanimate materials which are used as the electronic acceptors in mixture solar cells plays an important role in providing good performance. Among the four major inorganic material types which were scrutinized namely cadmium mixtures, silicon, metallic oxide nano particles besides short band gap nanoparticles, Cadmium Sulphide (CdS) quantum dots are having higher (>4%) power conversion efficiencies. As far as the academic and industrial communities are concerned, dye -sensitized solar cell has attained high priority in accordance with its good efficiencies, ease in manufacturing, low cost etc., Despite the above-mentioned advantages or the positive characteristics of vivid solar cells, the heed is towards the solar cells through extremely tinny absorber, solar cells by quantum dots absorber coatings. In accordance with which we have discussed about the quantum dot solar cells keeping electrical parameters as the highest priority. Herein we present some small review on recent studies in QD solar cells considering their electrical and impedance properties, effect of incorporation of nano materials in solar cells.
