For the first time, we report large-area (16 cm 2) independently certified efficient single perovskite solar cells (PSCs) by overcoming two challenges associated with large-area perovskite solar cells.
Some impressive attempts have contributed to fabricating large perovskite solar cells (PSCs) with a device size of approximately 1 cm 2 while retaining the high PCEs of small devices (~0.1 cm 2) (9 – 16).
A 16 cm 2 perovskite solar device at the cell level rather than at the module level is demonstrated using the modified solution process in conjunction with the use of a metal grid. The cell is independently certified to be 12.1% efficient.
The resulting perovskite solar cells (PSCs) exhibited PCEs of 24.42 % and 19.87 % for 0.1 cm 2 and 14.4 cm 2 (mini-module, aperture area). Taken together, these studies are mostly based on small-area devices, while relatively few studies are concentrated on large-area cell modules.
Relatively high PCE achieved in large area vacuum-deposited perovskite solar cell modules. A relatively wide humidity range is adoptable for the preparation of large-area perovskite by this method. Vacuum deposition is promising for large-area, high-throughput production of perovskite solar cells (PSCs).
Metal halide perovskite solar cells (PSCs) currently attract enormous research interest because of their high solar-to-electric power conversion efficiency (PCE) and low fabrication costs, but thei...
