Process Engineering and Interfacial Defects Passivation of Large Area Perovskite Solar Modules

8th World Conference on Photovoltaic Energy Conversion; 252-254
The industrial and economical transition of the perovskite (PVSK) photovoltaic (PV) technology is feasible by scaling-up effective PVSK recipe and post-treatment from small area cells ( 1 cm2) to sub-modules (≥ 200 cm2). In this work, we reported on the ambient air fabrication of a low temperature planar n-i-p PVSK submodule (total area 320 cm2, aperture area 201 cm2, 93% GFF) exploiting the defect passivation strategy, the PVSK composition and a hybrid blade/slot-die coating technique assisted by air and green antisolvent quenching method. Finally, the sub-module record efficiency is 16.13% with 7% and 0% losses with respect to small area cell and minimodule, respectively. Further details, characterizations, life cycle assessment (LCA) and stability test are in the full paper submitted to Progress in Photovoltaics.
