Abstract
This study presents the results of attaching colloidal Cesium Perovskites quantum dots Spin Coated on Silicon Solar Cells to Improve efficiency. Colloidal perovskite quantum dots of cesium lead were prepared with Bromine and Iodine. The photoluminescent of the quantum dots can be tuned by QD size. The important parameter in controlling the QD size is the temperature of the precursor solution. Our preliminary studies show that a combination of CsPb Br3 and CsPbI3 layers can be added as absorbing layers on the top silicon solar cells, which resulted in an enhancement of silicon conversion efficiency of about 18%.
