Research and Development for Continued Performance Improvement in Flexible a-Si PV

Abstract

There are many aspects to power generation from an amorphous silicon tandem solar module as produced by Power Film Inc. These include the tunnel junction between the top and lower layer of the cell, the life time, as affected by the Staebler-Wronski effect, and the band gap of the photon collecting layers. The manufacturing process and source materials have a large impact on each of these areas. In this study, the tunnel junction was modified to act as a recombination junction in order to reduce the reverse voltage bias. The intrinsic silicon layers were modified to minimize the Staebler-Wronski effect. Additionally, carbon was added as a dopant to the top intrinsic silicon layer to boost over all cell performance by modifying the band gap of the material.
