摘要
一种可用于可穿戴设备屏幕表面的透明非晶硅薄膜太阳能电池,采用激光刻蚀高密度微纳光通道阵列、TCO薄膜作为透明导电背电极,并减薄I层厚度来提升光线透过率。实验表明随着光刻密度增加或I层厚度的减少,光电转换效率会降低,光线透过率会增加,当I层厚度300nm,光刻孔隙直径30m,阵列间隔55m以内时,可获得50%以上的透过率(最高59%)和2.5%以上的光电转化效率(最高3%)。
A transparent a-Si thin film solar cell which use TCO film back electrode,thin I layer a-Si film,and micro light tunnel matrix structure that made by laser etching to get highly transmittance. Experiments show that the efficiency will decrease and the light transmittance will increase when the density of micro light tunnel matrix increased or the I layer thickness decreased.When the I layer thickness is 300 nm,and the micro light tunnel at a diameter of 30 m and the matrix spacing within 55 m,the transmittance50%（max 59%）,and the efficiency ≥ 2.5%（max 3%）.
