Does substrate temperature affect the back contact of thin film solar cells?

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.

Can SB2 SE 3 thin film solar cells be thermal evaporated?

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% .

What is the substrate configuration of SB 2 SE 3 thin film solar cells?

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.

What is a solar backsheet?

Initially, solar backsheets had a three-layer structure (PVDF/PET/PVDF). The outer PVDF layer offers excellent environmental corrosion resistance, the middle PET layer provides insulation, and the inner PVDF layer, combined with EVA, ensures good adhesion.

What is Tedlar® PVF film-based backsheet?

Tedlar® PVF film-based backsheet is the industry standard for solar backsheets Tedlar® PVF film-based backsheet designs have been in the field for more than 30 years in different climates, including deserts, tropical locations, seashores, and mountainous terrains. They have protected millions of solar panels across multiple geographies.

Why do thin film solar cells have a higher Voc and FF?

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%.
