| Abstract: |
Perovskite photovoltaics (PPV), due to their compatibility with a flexible substrate, low cost, and high indoor performance compared to existing inorganic and organic photovoltaic technologies, are emerging as a potential candidate to power the internet of things (IOT). Dual-cation and mixed halide [FA0.8Cs0.2Pb(I0.62Br0.38)3] (FACsPbIBr) based wide bandgap perovskite composition's long-term stability and energy bandgap made them ideal for indoor applications. In this work, we have developed the PPV devices using flexible substrate based on FACsPbIBr perovskite composition for indoor application. PPV were also fabricated on rigid substrate as control devices. The flexible and rigid substrate-based PPV devices delivered power conversion efficiency (PCE) of 17.02 (36.33)% and 18.90 (37.25)%, respectively, under AM1.5G (LED 2700 K, 1000 lux). Remarkably, flexible-PPV devices delivered open-circuit voltage (VOC) of 1.11 V under indoor light (1000 lux). The study suggests the potential of flexible substrate-wide bandgap perovskite-based PPV for futuristic IOT applications. |
