Roll-to-roll fabricated perovskite solar cells under ambient room conditions
The translation of perovskite solar cells to large-area devices fabricated by industry-relevant manufacturing methods remains a critical challenge. Here, authors report solar modules with serially-interconnected cells produced entirely by industrial roll-to-roll printing under ambient conditions.
This significantly reduces the amount of crystalline defects, and amorphous glassy films can be fabricated that are then converted instantly to a perovskite when the methyl ammonium iodide (MAI) solution is deposited, as shown in Supplementary Fig. (centre line, median; diamond, mean; box limits, upper and lower quartiles; whiskers, 1.5× interquartile range; linecross, outliers) ( h) PCE of 1600 consecutively fabricated PeSCs and deposition parameters along the position of the flexible film.
