When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non-Fullerene Acceptor Blends Can't Be Efficient
{{output}}
It is a well-established fact that the energetic offset between the donor and the acceptor components in organic solar cells dictates the tradeoff between photovoltage and photocurrent losses. Yet, a deeper understanding of the photophysical processes that ult... ...
