Abstract

Quantum dot solar cells are solution-processable, lightweight, and low-cost, and their long-term stability makes them attractive to explore for aerospace applications. In this work, we have studied lead sulfide (PbS) colloidal quantum dot solar cells (CQDSCs) using three different types of hole tran...
