Abstract

The compact thin films of Cu₂MnSnS₄ nanoparticles are in situ prepared on ITO substrate by spin-coating precursor solution combined with a short thermal annealing (5 min) at low temperature (∼300 °C). The as-prepared Cu₂MnSnS₄ nanoparticle film exhibits a bandgap of 1.63 eV and an absorption coefficient of >10⁴ cm⁻¹ within 300–900 nm. The ultrathin solar cell structured as ITO/Cu₂MnSnS₄/CdS/Al with 65 nm-thick Cu₂MnSnS₄ film is firstly fabricated and achieves a peak efficiency of 0.50 %. Moreover, this solution-processing method could be extended to prepare other Cu₂MSnS₄ (M = Co, Ni, Cd and Mg) nanoparticle films for photovoltaics.

超薄太阳能电池用溶液处理Cu2MnSnS4纳米颗粒薄膜

采用自旋涂覆前驱体溶液结合低温（~ 300℃）短时间热退火（5 min），在ITO衬底上原位制备了Cu2MnSnS4纳米颗粒致密薄膜。制备的Cu2MnSnS4纳米颗粒膜在300 ~ 900 nm范围内的带隙为1.63 eV，吸收系数为104 cm−1。首次制备了ITO/Cu2MnSnS4/CdS/Al结构的超薄太阳能电池，其Cu2MnSnS4薄膜厚度为65 nm，峰值效率为0.50%。此外，这种溶液处理方法还可以推广到其他Cu2MSnS4 （M = Co, Ni， Cd和Mg）纳米颗粒薄膜的制备。
