Abstract The performance of colloidal quantum dots (CQD) solar cell lags behind due to the carrier recombination within the quasi-neutral region (QNR). To overcome such issues, researchers exploited graded band alignment technique by piling CQDs of different size. In addition, the electron and hole transport layers, i.e., ETL and HTL highly impact the
