技術簡介

目前四端點鈣鈦礦-矽晶堆疊太陽光電模組的研究成果，在面積與效率仍離商用階段有不小的距離。對於大尺寸四端點堆疊太陽光電模組而言，大面積與高效率的關鍵在於上半部，也就是半穿透鈣鈦礦太陽光電模組。影響大尺寸半穿透鈣鈦礦太陽光電模組效率的因素包含吸收層均勻性、透明導電背電極品質及模組裡電池連接設計等。本研究開發一種新型結構，透過此結構可大幅減輕因透明導電背電極導電性差引起的損耗，活性面積4 cm2的半穿透鈣鈦礦太陽光電模組最高效率可達15.8％。

Abstract

The research results of four-terminal perovskite-silicon tandem solar cells are still far from the commercial stage in terms of area and efficiency. For large scale four-terminal tandem solar modules, the key to large area and high efficiency lies in the top half, that is, the semi-transparent perovskite solar modules. Factors affecting the efficiency of large scale semi-transparent perovskite solar modules include the uniformity of the absorber layer, the quality of the transparent conductive back electrode, and the design of cell connection in the module. Through the new pattern of this study, the loss caused by the poor conductivity of the transparent conductive back electrode can be greatly reduced. The efficiency of perovskite-silicon tandem champion solar module with an active area of 4 cm2 reaches 15.8％.
