摘要: Through the analysis of scales and simplification drift-diffusion device model, we have obtained a quantitative description mechanisms underlying current-voltage (j–V) characteristics organic bulk-heterojunction solar cells. The been resolved into competition between photogeneration, recombination, extraction/injection rates, which determines bulk charge carrier concentration; combined effect built-in field boundary layers in shaping electric potential distribution, field. relationships j–V standard model parameters captured with analytical expressions verified through 1-D numerical simulations. We determined that while generation rate can be reliably extracted from measurements alone, effective density states potential, mobility recombination prefactor are clustered pairs only decoupled other characterization techniques.
