STUDY OF TOP CONTACT P-LAYER JUNCTION FOR THE OPTIMIZATION OF LARGE-AREA AMORPHOUS SILICON MULTIJUNCTION CELLS

摘要

The role of the junction between the top contact transparent conducting oxide (TCO) film and the underlying p-layer on the performance of hydrogenated amorphous silicon (a-Si) solar cells has been investigated. The ''compatibility'' of the properties of the TCO and p-films have been found to affect cell performance. Optimization of the deposition parameters for the TCO and p-layer films has resulted in superior cell performance, better uniformity over large (similar to 900 cm(2)) area, and double-junction module efficiency as high as 11.4%.
