Abstract

Organic solar cells (OSCs) have gained much research attention for its ease of manufacturing, high efficiency and potential application to role to role processing on flexible substrates. Opto-electronic device modelling plays a crucial role to understand the devices and effectively improve its performance. The talk will emphasise on the development of a general model to describe spectral response and current-voltage characteristics of OSCs and its application to understand important phenomenon like optical effects in thin film stack, exciton diffusion, exciton dissociation and the role of active layer and contacts in device efficiency. An efficient way to select optimum thicknesses of the constituent layers and brief comment on the degradation mechanism will also be presented in the talk.
