Abstract

original image

Mismatched dye solar cells in modules can be forced to operate in reverse bias (RB). As shown on p. 2964 ff. by T. M. Brown et al., 0.4 V in RB with time has little effect on cell efficiency whereas harsher but real tests leads to increasing overpotentials at electrodes causing H2 evolution, dye degradation and breakdown.
