6 FAQs about [Organic solar cell circuit]

What is open-circuit voltage (V OC) in organic solar cells?

Open-circuit voltage (V OC) in organic solar cells (OSCs) is currently still not well-understood. A generally acceptable view is that V OC is mainly determined by the energy level offset between donor and acceptor materials. Recently in ternary blend OSCs, V OC is found to be dependent on the blend composition.
