Abstract:Is it possible that one day flexible assembly, repeated detachment, facile repair and maintenance will all be realized for photovoltaic devices? Our work provides a feasible strategy. A flexibly assembled and readily detachable stacking perovskite solar cell (S-PSC) consisting of two individual half cells is reported for the first time. High adaptability to various electrode substrates is demonstrated, which endows S-PSCs with promising prospects in future manufacture and applications. Considering that a robust interface between two half cells is an essential precondition for repeated detachment, a series of interfacial modifications are conducted and eventually considerable power conversion efficiencies (PCEs) of up to 14.62% are attained. Meanwhile, the S-PSCs can withstand repeated assembly and disassembly tests more than 100 times without a decline in the PCE. This work charts a new path for future innovative design of solar cells featuring flexible and facile production, storage, and cost-effective repair and maintenance.
