Exciton Dynamics and Charge Carrier Generation in Organic Semiconductors

Abstract

Chapter 1. General IntroductionSolution and vacuum processable organic solar cells (OSCs) have recently been in the spotlight as an attractive energy source owing to their continuously rising power conversion efficiencies. In this manner, it is fundamental to critically assess and revise the current understanding of the basic working principles of OSCs, in particular the early times photophysical processes that leads to photocurrent generation. This introductory Chapter provides an overview of the photophysical processes in organic semiconductors relevant to OSCs.
