Reliable perovskite indoor photovoltaics for self-powered devices
The rise of the Internet of Things has spurred a rapid increase in demand for self-powered devices, accompanied by the swift development of highly compatible indoor photovoltaics. Perovskite indoor photovoltaics (PIPVs) have garnered significant attention due to their tunable bandgaps, high output voltage etc. Long-term stability is the most critical hurdle for the commercialization of PIPVs and is under intense market scrutiny. The stability of self-assembled monolayers in inverted PIPVs plays a pivotal role in determining device stability. In this work, we employ an interlocking self-assembled monolayer strategy that enhances device stability by improving film coverage. Optimized devices achieve a record indoor photovoltaic power conversion efficiency of 42.01% under 1000 lx illumination. Furthermore, in the accelerated aging stability test simulating a day/night cycle with light intensity fluctuating from 2000 to 0 lx, the projected T90 lifespan of the final target device approaches 6000 h. Ultimately, the PIPV module, through the integration of integrated circuits, achieved continuous and reliable operation of an electronic price tag.
