Charge Generation Dynamics in Organic and Perovskite Solar Cells

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Over the past few decades, research interest in understanding the device physics and operation of organic and perovskite solar cells has considerably increased. This is because organic and perovskite solar cells are promising candidates for low-cost and high- efficiency solar cells with the need for further improvements in their performances. Charge carrier dynamics play a critical role in the operation of these devices. In this chapter, we present : 1) mechanism and rate of intersystem crossing from singlet to triplet excited state to reduce recombination losses, 2) exciton diffusion to the D-A interface for dissociation in organic solar cells (OSCs), and 3) influence of interface energetics and charge carrier mobility on the open-circuit voltage in perovskite solar cells (PSCs).
