Solutions to Overcome SQ Limits for Modelling Efficient Solar Cell and Introduction to Novel QD-MJSC Design

Abstract

Abstract Harnessing the solar power with maximum energy conversion efficiency can fulfill every electrical demand of the world. Depending on the designing of models, the commercial solar cell is being tested. To harness the entire energy on optimum cost, the material is selected in such a way that the overall outcome become beneficiary. In recent market available solar cell, there are still more criteria to be taken care of to improve the efficiency. This paper visualizes the solutions to overcome the Shockley–Queisser (SQ) limits based on also the loss analysis of recent market available solar cells. Graphene’s electrical, thermal and nano particle properties for solar cell usage will lead the cell efficiency to the top level. Multi-junction cells and quantum dot cells will increase the rate of recent research flow, if graphene is attached by coupling with the model.
