Abstract
Internal photocurrent quantum yields near 100% can be obtained from the separation of loosely bound geminate pairs when sufficiently large electric fields are applied to organic heterojunctions. The fields needed for complete electron–hole dissociation decrease to those prevailing in organic solar cells under operating conditions when well-conjugated polymers are employed.Keywords
