Leakage of photocurrent： an alternative view on I-V curves of solar cells

An altemative way is proposed to interpret I-V characteristics of GalnP single-junction solar cells by position-dependent leakage ofphotocurrent. With this approach, the I-V curves of solar cells under non-uniform illumination are well analyzed. The effective spreading resistance is also extracted t...

Summary:An altemative way is proposed to interpret I-V characteristics of GalnP single-junction solar cells by position-dependent leakage ofphotocurrent. With this approach, the I-V curves of solar cells under non-uniform illumination are well analyzed. The effective spreading resistance is also extracted to understand the dynamic behavior of between the open-circuit voltage and short-circuit current points. The conditions under which the one- diode model will fail are addressed in detail. These analyses are also applicable for a characterization of the I-V curves with lateral voltage distribution under uniform illumination.
