Description
Scaling-up perovskite solar cells (PSCs) is a prerequisite to the adoption of perovskite photovoltaics. However, the performance and stability of perovskite solar modules (PSMs) have lagged behind those of lab-scale PSCs. The development o PSMs requires interfacial passivation, yet this is challenging for the buried interface, owing to the dissolution of passivation agents during perovskite deposition. Here, we overcome this limitation with in-situ buried interface passivation – achieved via directly adding a cyanoacrylic acid-based molecular additive into the perovskite precursor solution. The preferential buried interface passivation results in facilitated hole transfer and suppressed surface recombination. We report a power-conversion efficiency (PCE) of 20.3% for inverted-structure PSMs.
