“…Among photovoltaics, PPVs already exhibited the highest specific power per weight (W/g) and excellent mechanical properties rendering them foldable, crumbly, and stretchable. From these advantages, there are various electronic applications, such as temperature sensors [ 117 ], integrated circuits with LEDs [ 63 ], e-paper [ 120 ], unmanned aerial vehicles [ 121 ], and wearable solar clothing [ 29 ]. However, it remains challenging to improve the stability of flexible and lightweight PPVs under extreme environmental conditions such as humidity, stress, and scratching.…”

The development of digital technology has made our lives more advanced as a society familiar with the Internet of Things (IoT). Solar cells are among the most promising candidates for power supply in IoT sensors. Perovskite photovoltaics (PPVs), which have already attained 25% and 40% power conversion efficiencies for outdoor and indoor light, respectively, are the best candidates for self-powered IoT system integration. In this review, we discuss recent research progress on PPVs under indoor light conditions, with a focus on device engineering to achieve high-performance indoor PPVs (Id-PPVs), including bandgap optimization and defect management. Finally, we discuss the challenges of Id-PPVs development and its interpretation as a potential research direction in the field.

“…By 2030, it is estimated that the share of perovskite photovoltaics may pass 29% of the global market. [ 126 ] And the PSC's global market size is projected to reach around $7.2 billion. [ 127,128 ] Accordingly, the cumulative value of the recyclable materials in decommissioned PSCs will be approximately billions of dollars worldwide by 2030.…”

To date, the highest certified efficiency has reached 25.7% for laboratory‐scale perovskite solar cells (PSCs). Breakthroughs in the commercialization of PSCs is achieved continuously. Therefore, the recovery of decommissioned devices that are closely related to the commercialization is extremely urgent. More importantly, lead (Pb) and other materials in PSCs are ecotoxic and biotoxic. Due to improper disposal of the decommissioned devices, serious heavy metal Pb and solid waste pollution incidents may occur. In fact, PSCs contain a great deal of recyclable and valuable materials. To achieve the goal of sustainable PSCs, recycling and reusing these useful materials are advocated. In this review, the authors retrospect structures and key materials of PSCs briefly. Benefits of recycling useful materials from the decommissioned PSCs are analyzed in terms of environmental and economic profits, including reducing the material costs, saving energy, reducing negative environmental impacts and conserving natural resources. Research progresses on recycling and reusing the useful materials are summarized and discussed from the perspectives of feasible pathways, recovery solvents, recovery effects and performance analysis of the corresponding devices. Finally, current challenges and future opportunities to prevent Pb leakage and recycle PSCs in an environmentally viable manner are proposed toward sustainable development.

“…[19][20][21] Due to the fast development of photovoltaic technologies, the investigation of IPVs may focus more on third-generation photovoltaic technologies including organic photovoltaics, dye-sensitized cells, and perovskite cells. [22][23][24][25][26] Among these, the perovskite cells exhibit tremendous potential for high-indoor efficiency devices owing to the desirable optoelectronic characteristics such as tunable bandgap (ranging from 1.2 eV to about 3.5 eV), high optical absorption coefficients (10 5 cm −1 ), small exciton binding energy (<100 meV) and long carrier diffusion length (over 1 µm). [27][28][29] Nowadays, the record indoor power conversion efficiency (PCE) of perovskite cells has exceeded 40% (under 1000 lux), which far exceeds other types of cells.…”
