Metal halide perovskite solar cells (PSCs) are established as a highly promising next-generation photovoltaics (PVs) technology due to their superior optoelectronic properties, such as high light absorption coefficient, long carrier diffusion length, high carrier excitation, and transport ability. [1][2][3][4][5] In just a few years, it has achieved a power conversion efficiency (PCE) of over 25.7%, comparable to silicon PVs. [6][7][8][9] While Pb-based PSCs exhibit exceptional promise for mass production, [10][11][12] there are growing concerns about their environmental impact due to the potential toxicity and leaching of harmful Pb species throughout their lifetime.Colloidal quantum dots (QDs) are another promising candidate for the nextgeneration PV application, which has received enormous attention because of the excellent optical and electronic properties enabled by their unique size-dependent quantum confinement. [13][14][15] Pb chalcogenide QDs (e.g., PbS, PbSe) are among the most promising nanoparticle (NP) materials in PVs, with certified PCEs as high as 13.8% in PbS QDSCs. [16,17] The low-cost and scalable solution-based processing methods can offer QDs a wide range of bandgaps, and generally better stability than organic chromophores. Despite the continuously increasing PCEs of QDSCs, device stability remains a significant challenge for industrial applications. Beyond PV, QDs have further demonstrated their promising application in biomedical imaging, display and electronics industries. Similar to Pb-based PSCs, growing concerns also arise from their potential Pb 2þ toxicity, Emerging Pb-based photovoltaic (PV) technologies, including in particular solution processed halide perovskite solar cells (PSCs) and Pb chalcogenide quantum dot solar cells (QDSCs), are among the most promising next-generation PV technologies for a range of disruptive energy and electronic applications. However, the potential toxicity and leakage of hazardous Pb species have become one of the main barriers to their large-scale application. When solar cells are subject to physical damage or failure of encapsulation, rapid leakage of Pb may occur, which can be accelerated by exposure to external environmental weathering conditions such as rainfall and elevated temperature. Herein, an in-depth investigation on the essential role of Pb in PSCs and QDSCs, as well as common causes of Pb leakage, is undertaken. The hazardous effects of Pb toxicity on soil plants, bacteria, animals, and human cells are also evaluated. Recent progress in developing effective strategies for Pb leakage reduction, such as Pb-free or Pb-less perovskite materials, device architecture design, encapsulation absorbers for PSCs, and core-shell structure and ligand exchange method for QDSCs, in addition to Pb recycling strategies of end-of-life solar cells are summarized. This review provides quantitative insights into the future development of eco-friendly emerging Pb-based PV technologies.

“…As a result, the efficiency and the stability of perovskite photovoltaic device are promoted. The light is also able to break the bonds of precursors and produce halide ions for the formation of perovskites 43 . The photoinduced modification of the surfactants also enables controlling the surface states of the perovskite nanocrystals (NCs), which is adopted to modulate the solubility of NCs in the solution for patterning 45 .…”

“…In the first case, photoirradiation is an effective and facile technique to control the concentration of components such as halide ions that form perovskites. For example, ultraviolet (UV) light irradiation can break the covalent carbon-halogen (C-X) bond of haloalkanes and produce halide ions for synthesis of perovskites 43 . Based on this principle, CsPbX 3 NCs and nanocomposites (such as upconversion nanoparticles@mSiO 2 @CsPbX 3 core/shell structures) were prepared in the solution, which open up new opportunities for multifunctional perovskite-based materials and devices for photonic applications.…”

The past two decades have seen a drastic progress in the development of semiconducting metal-halide perovskites (MHPs) from both the fundamentally scientific and technological points of view. The excellent optoelectronic properties and device performance make perovskites very attractive to the researchers in materials, physics, chemistry and so on. To fully explore the potential of perovskites in the applications, various techniques have been demonstrated to synthesize perovskites, modify their structures, and create patterns and devices. Among them, photo-processing has been revealed to be a facile and general technique to achieve these aims. In this review, we discuss the mechanisms of photoprocessing of perovskites and summarize the recent progress in the photo-processing of perovskites for synthesis, patterning, ion exchange, phase transition, assembly, and ion migration and redistribution. The applications of photo-processed perovskites in photovoltaic devices, lasers, photodetectors, light-emitting diodes (LEDs), and optical data storage and encryption are also discussed. Finally, we provide an outlook on photo-processing of perovskites and propose the promising directions for future researches. This review is of significance to the researches and applications of perovskites and also to uncover new views on the light-matter interactions.

Modern electronics face formidable challenges in energy efficiency and durability. Owing to their safety, lightweight design, and simplicity, indoor photovoltaics (IPVs) have garnered substantial attention among various sustainable power sources. Remarkable progress is made in IPVs, achieving power conversion efficiencies (PCEs) ranging from 3.6% using silicon materials in 2011 to an impressive 42.43% using current perovskite materials. Although numerous summaries exist, most reviews of IPVs have narrowly focused on single active materials and lack a systematic overview across different material categories starting from fundamental design principles. This comprehensive review addresses this knowledge gap by introducing IPVs fabricated based on silicon, dye, III‐V, organic, and perovskite materials, compares the PCEs of these devices for indoor applications, and provides an overview of the advantages and disadvantages associated with the different materials. For the most promising materials, optimization and modification schemes are presented for perovskite‐based IPVs. The standardized testing of IPVs and urgent challenges encountered in their development are emphasized. This review offers valuable guidance for material selection and device design for future IPVs to facilitate PCE improvement and challenge resolution in the field of IPVs.
