Abstract :
Solar cells consisting of quantum dots of the same size have been worked on till date. Our work focuses on varying the size and increasing the Incident Photon to Current Conversion Efficiency of the intrinsic layer of a Silicon solar cell. We have been able to increase the IPCE up to 70% and 140% by widely varying the sizes of Cadmium Selenite and Cadmium Telluride quantum dots respectively. Their total volume fractions were kept constant.
