Abstract

White light bias External Quantum Efficiency (EQE) measurements made on organic tandem cells are demonstrated to provide a quick and direct measurement of current-balancing. EQE measurements under white light bias can therefore be used to help guide or measure optimisation in asymmetric multi-junction cells.
