A method is presented which suggests the sharing out of total cell short circuit current among the constituent parallel branches of the equivalent circuit, allowing for the identification of their contributions to the total current–voltage (I–V) characteristics under illumination in solar...

Current–voltage characteristics of ZnO/CdS/CuGaSe2 single crystal solar cells which have gone through repetitive annealing treatment were analysed using the two-diode equation. The fitting analysis revealed that current transport in these cells is governed by two competing transport mechanisms...
