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.
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% .
The development of lightweight and flexible modules, both for thin-film solar cells and c-Si solar cells, along with the utilization of stacked solar cell modules, will be an important future issue in the solar cell industry.
Commercial thin-film CdTe solar cells use Cu-doped ZnTe (ZnTe:Cu) as the hole-selective back contact. However, ZnTe:Cu fails to passivate the back interface or form desired electron reflection to enhance performance (3, 10).
The lower surface energies and less of dangling bonds of termination of these phases leads to an increase VOC and FF, and the better carrier transport allows enhanced J SC. We have obtained substrate configuration Sb 2 Se 3 thin film solar cells with a champion efficiency of 4.25%, V OC of 427 mV and FF of 58.15%.

Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers to a few microns thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick.
