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.
