Analytical expression for the current-voltage characteristics of organic bulk heterojunction solar cells

An expression to describe the current-voltage characteristics of organic bulk heterojunction (BHJ) solar cells is derived. The derivation is obtained by analytically solving the drift-diffusion model for organic BHJ solar cells with the assumption of uniform bimolecular recombination rate. The assum...
