|Non-Fullerene Acceptors in High-Efficiency Organic Solar Cells|
Organic solar cells containing non-fullerene acceptors such as m-ITIC blended with conjugated polymers have impressive efficiencies. One reason is the low driving force for charge transfer, allowing high photovoltage. However, this might slow down charge generation, leading to a tradeoff between voltage and current.
