STUDY ON THE DEGRADATION AND STABILITY OF
AMORPHOUS/MICROCRYSTALLINE SILICON THIN
FILM SOLAR CELLS

ABSTRACT

In order to raise the popularization of silicon solar cells, the producing cost must
be reduced and the stabilized conversion efficiency must be improved. Improving the
stability of silicon thin film solar cell is as important as improving the initial
performance. In this paper, silicon thin film solar cells were investigated.
Two kinds of silicon thin film solar cells were prepared to investigate the
degradation. One is low temperature single junction based amorphous silicon thin film
solar cells were prepared under different silane concentration and power. The other
one is P-type single junction based microcrystalline silicon thin film solar cells with
different TCO and substrate temperature. The measurements of the I-V、Raman and
SIMS were conducted before, during and after light-soaking. The main reason of the
degradation of materials was discussed.
Tandem silicon thin film solar cells with different I layer and electrode were
used to perform light soaking experiments under different light sources. The J-V
parameter 、quantum efficiency (QE)and Raman spectroscopy were measured during
