Solliance announced a new record stabilized average cell performance of 14.5% for its large thin-film perovskite photovoltaic modules on glass. The efficiency was measured on an aperture area of 144 cm2.
The perovskite module was realized on a commercial 6x6 inch2 glass substrate, a size comparable to standard commercial silicon solar cells. The substrate is provided with a transparent conductor, by applying three consecutive slot die coating processes and using a newly developed annealing process. The metal top electrode was evaporated. Twenty-four cells were series-connected through optimized laser-based scribes. Up to 95.3% of the modules area is covered with active material, resulting in a stabilized module efficiency of 13.8%.
