Abstract

In this paper we present a new analytical model for the direct bias capacitance in p-i-n amorphous silicon solar cells. The model includes the contributions due to band tails and dangling bonds trap states in the diffusion capacitance.

Experimental measurements of capacitance versus direct bias voltage are presented, showing a very good agreement with theoretical predictions.

The presented model, requires a very short computer time, being based on the analytical treatment of the p-i-n structure; this allows an easy comparison with experimental measurements.
