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% .
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.
TPT is the abbreviation for the composite material of “Tedlar film→Polyster→Tedlar film”. Tedlar is a registered trademark of DuPont. It is a polyvinyl fluoride film used on the back of the module as a backside protective packaging material.
Another important application of thin films in PV is the antireflection coating (ARC) on the surface of solar glass where the light first reaches the solar panels. Currently, single-layer antireflection coated solar glass has a dominant market share of 95% compared to glass with other coatings or no coating, for Si PV modules [ 2 ].
One of the critical steps in fabricating IBC solar cell is defining the emitter and the base regions on the rear side. The common process to create the emitter in conventional silicon solar cell is by using the diffusion process. In the diffusion process, dopants are introduced to all silicon wafer surfaces in high temperature furnace.
