Surpassing the 10% Efficiency Threshold in Perovskite-Inspired Indoor Photovoltaics

Perovskite-inspired materials (PIMs) are promising candidates
for
low-toxicity indoor photovoltaics (IPVs), but their power conversion
efficiencies (PCEs) have been so far largely limited by poor thin-film
morphology and suboptimal device architectures. Here, we report a
PCE exceeding 10% under 1000 lux indoor lighting by integrating device
and film engineering strategies, including a dual-purpose interfacial
modifier atop a hybrid antimony–bismuth halide PIM, advancing
the development of efficient pnictogen-based IPVs for Internet of
Things (IoT) applications.
