摘要
CuPbSbS3 has excellent photoelectric properties, such as high element abundance and optical absorption coefficient, and a suitable band gap, which is a material with the potential for absorbing layers of high-quality thin film solar cells. In addition, CuPbSbS3 is a material with a three-dimensional structure, which can guide the carrier to transport in all directions, so its performance can be regulated in multiple dimensions. At present, the substrate structure is often used in efficient solar cells since this structure does not affect other functional layers when the absorption layer is subjected to harsh annealing conditions. However, there have been no reports of the substrate structure of CuPbSbS3 solar cells so far. Therefore, in this work, CuPbSbS3 films deposited on a stable substrate of molybdenum (Mo) were prepared with butyldithiocarbamic acid (BDCA) solution, and the preparation process of reaction mechanism was described in detail. It was found that the band gap of the CuPbSbS3 thin film was 2.0 eV and the absorption coefficient was up to 105 cm−1, which is expected to be applied to the top absorption layer material in laminated cells. Thus, we first built a Glass/Mo/CuPbSbS3/CdS/ZnO/ITO substrate structured solar cell. From this, a photoelectric conversion efficiency of 0.094% was achieved. This work provides a tentative exploration for the future development of substrate structured CuPbSbS3 solar cells.
