Kinetic Monte Carlo modeling on organic solar cells: Domain size, donor-acceptor ratio and thickness
Publikováno v:
Nano Energy. 35:128-137
Organic solar cells have received a lot of attention in the last few decades. Extensive experimental work has been conducted to improve organic solar cell performance. However, a much more realistic and accurate model needs to be developed that can s
