Abstract Indoor photovoltaics (IPVs) based on halide perovskites (HPs) and derivatives (HPDs) hold great promise for powering the vast infrastructure of Internet-of-Things (IoT) smart devices. While lead-containing IPVs deliver cutting-edge performance, environmental concerns have spurred research into lead-free alternatives. However, sustainability these IPV technologies remains underexplored, with lead-based versus debate confined to elemental considerations, neglecting life-cycle impacts requirements. This study presents first comparative assessment (LCA) addressing vs. HP/HPD dilemma, examining absorbers, precursors, functional layers, fabrication steps. A modelling framework is introduced evaluate net gains (NEGs) compared conventional battery-centric approach Our findings challenge assumptions that are inherently more eco-friendly than their counterparts. Moreover, we demonstrate Pb- Sn-based can achieve NEGs after just 3–4 weeks 4–7 weeks, respectively, significantly outperforming mainstream IPVs. In contrast, Sb- Bi-based align IPVs, limiting potential unless efficiencies increase ~40%. Key strategies enhance eco-friendliness policy considerations Pb-based IoT outlined.

Abstract Organic photovoltaics (OPVs) and organic photodetectors (OPDs), which use conjugated polymers molecules as photoactive materials, hold significant promise for energy harvesting sensing applications due to their customizable optoelectronic properties, potential mechanical flexibility, compatibility with low‐cost, high‐throughput manufacturing. However, OPV OPD research date has typically relied on device fabrication in controlled environments (e.g., glove boxes filled inert gases) vacuum‐deposited (rather than solution‐processed) electrodes, limiting scalability increasing manufacturing complexity cost. This review explores these challenges by surveying the development of ambient‐air‐processed, solution‐based (APSB) OPVs OPDs, not only solution‐processed electrodes but are also entirely fabricated under ambient conditions. Various solution processing techniques, performance APSB OPDs comprehensively examined, offering insights future advance technologies toward ultra‐low‐cost optoelectronics harvesting.
