Abstract

Silicon solar cells and perovskite solar cells were fabricated by non-vacuum printed processes in our group. Screen-printing, spin coating and spray pyrolysis deposition techniques were utilized mainly. Low temperature and non-vacuum processed TiO2 layer and Al2O3 layer and Al2O3/TiO2 double layer were introduced as an alternative anti-reflection coating film. In-house developed polyvinyl alcohol based aluminum pastes were also introduced for solar cell applications. p-type crystalline silicon solar cells were fabricated with over 17% conversion efficiency with non-vacuum processes. On the other hand, perovskite solar cells using organic or inorganic hole-transporting materials can be reach the conversion efficiency over 12%. Finally, a two terminal tandem solar cells with structure of were fabricated using these solar cells and V-oc of 1.38 V was achieved.
