Abstract
We demonstrate the scaling up of the perovskite photovoltaic technology with minimal performance losses by developing stable device architecture with industrially compatible processes. The monofacial (aperture area: 784 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) and bifacial (aperture area: 781 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) perovskite solar modules exhibit a power conversion efficiency of 13.1% and 11.9%, respectively. Moreover, the encapsulated bifacial mini-modules (aperture area: 4 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) retained ∼92% of initial PCE after 1000 h of damp heat test.
