Thus far, a-Si/µc-Si tandem solar cell modules with conversion efficiency exceeding 13% have been reported. In addition, triple-junction solar cells, whose target year for practical application is 2025 or later, are introduced, as well as innovative thin-film full-spectrum solar cells, whose target year of realization is 2050.
The effect of substrate temperatures was studied and optimized. An additional selenization process, forming a thin MoSe 2 layer on the Mo back contact, was introduced prior to the deposition of Sb 2 Se 3 layer, which was found to further improve the back contact of substrate Sb 2 Se 3 thin film solar cells.
The back contact is the part of the solar cell on the other part of the sunny side, and its task is to contact the cell with the external circuit. Usually with other technologies, as in the case of CuInGaSe 2 or Cu 2 ZnSnSe 4, a metal such as molybdenum would be sufficient for contacting the cell.
For back-contact solar cells, some of the regions need to be blocked from the diffusion process. These regions might include the base region and the compensated region. This process of masking and patterning of the emitter and the base regions, makes the fabrication process more complex compared to conventional silicon solar cell.
Unfortunately, research on substrate structural Sb2 Se 3 thin film solar cells is very limited except the report by Chen et al., in which the Sb 2 Se 3 absorber layer were thermal-evaporated on fluorine-doped tin oxide (FTO) glass. The device achieved an efficiency of 2.1% with a V OC of 354 mV and a FF of 33.5% .
With ongoing research and development activities, as well as improvements in the fabrication technology, back-contact silicon solar cells are expected to be mass-commercialized in the near future. It is hope that future energy sources would be greener and more sustainable, thanks to the advancements in the photovoltaic technology.
In this work, we fabricated Sb 2 Se 3 thin film solar cells with substrate configuration of Ag/ITO/ZnO/CdS/Sb 2 Se 3 /Mo/glass. The Sb 2 Se 3 absorber layers were deposited via thermal evaporation of Sb 2 Se 3 and Se powders. The effect of substrate temperatures was studied and optimized.
