6 FAQs about [Solar cell back film composition]

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.
