背景技术Background technique
晶体硅太阳能电池占据了光伏市场电池量的80％以上的份额，并且有望成为未来电力供应的主要支柱。降低太阳能电池的成本是光伏发电民用化的一个重要方向。目前商业的制作晶体硅太阳能电池背电极的方法是采用丝网印刷银导电浆料的方法，该工艺简单成熟，便于规模化生产。但是，银导电浆料成本相对较高。如何采用非银(或少银)材料制备电池的背面电极，是目前太阳能电池降低成本的一个重要方向。Crystalline silicon solar cells account for more than 80% of photovoltaic market cell volume and are expected to become the mainstay of future electricity supply. Reducing the cost of solar cells is an important direction for the civilian use of photovoltaic power generation. The current commercial method for making the back electrode of crystalline silicon solar cells is to use screen printing silver conductive paste, which is simple and mature, and is convenient for large-scale production. However, the cost of silver conductive paste is relatively high. How to use non-silver (or less silver) materials to prepare the back electrode of the battery is an important direction for reducing the cost of solar cells at present.
