For organic photovoltaic materials with a high power conversion efficiency, polythiophenes and fullerene derivatives are often used as donor and acceptor materials. However, the power conversion efficiency has not reached the practical one, 15% and, therefore, new organic photovoltaic materials should be designed and developed. This study searches for novel organic photovoltaic materials by computational science. Specifically, we examine new donor-acceptor type polythiophenes used as a donor material in organic photovoltaics.
