Abstract

This work implemented the Beer-Lambert law of attenuation into the simulation of excitons in organic solar cells;
Our simulations suggest that the positional disorder of typical polymers, when reproduced in the simulation, is revealed as a CSP increase factor, but a minor one.

Obrigada pelo interesse! Infelizmente o tempo máximo de vídeo foi muito curto (apenas 6 minutos) e não pude explicar várias coisas importantes do trabalho. Mas com sorte será publicado um artigo com a pesquisa completa em breve. Resumidamente, os resultados são obtidos a partir de um software que utiliza o método Monte Carlo para dispersão dos éxcitons e cargas, usando a taxa de Forster para os éxcitons e a taxa de Miller para as cargas.
