由于有机太阳能电池具有成本低、易加工、可以制作在柔性衬底上等优点备受人们关注.文中采用了溶液旋涂的加工方法,研究了基于聚3-乙基噻吩(P3HT)与富勒烯衍生物(PCBM)共混的有机聚合物体相异质结太阳能电池.在大气条件下完成了器件的制备与测试,通过旋涂条件、质量分数、退火条件等优化提升了器件的光电特性,获得开路电压(Voc)为0.62 V,短路电流密度(Jsc)为14.97 mA/cm2,填充因子(FF)为42.21%,电池效率(PCE)为3.92%的高效聚合物体相异质结太阳能电池.因此,通过对溶液加工条件的优化,可以提高薄膜质量,促进载流子传输和分离的能力.不仅可以提升有机聚合物体相异质结太阳能电池的效率,也为推进有机太阳能电池的量产化奠定了基础.
