Development progress of thin crystalline silicon solar cell

薄晶硅太阳电池减少硅材料厚度不仅能降低材料消耗和电池成本,还可以赋予其一定的柔韧性,拓展其在可穿戴设备、建筑光伏一体化等领域的潜在应用,成为目前太阳电池领域的研究热点。近年来的研究工作多集中在通过纳米图案化结构、等离激元效应等途径增强薄晶硅对太阳光,尤其是长波长太阳光的吸收,以弥补硅吸收层薄化后引起的吸光能力不足的问题。本文将侧重从图案化纳米结构、等离激元效应增强薄晶硅电池的光吸收性能、薄晶硅太阳电池电学性能的优化、新型薄晶硅太阳电池等方面,对薄晶硅太阳电池的发展现状进行阐述。

Thin crystalline silicon solar cell with reduced thickness can save silicon material consumption and reducethe cost of solar cell. Besides, it can also be extended to apply potentially in fields of wearable devices and buildingintegrated photovoltaic due to its flexibility. It has attracted tremendous attention from researchers. The researches in recentyears mostly focus on optical absorption enhancement of thin crystalline silicon, especially long wavelength light, to offsetlow optical absorption after silicon material decrease through patterned nanostructures and surface plasmon polaritons. Inthis paper, current research of thin crystalline silicon solar cell about optical absorption enhancement by patternednanostructures and plasmon polaritons effect, optimization of electrical properties and novel thin crystalline silicon solarcell are reviewed.
