“…[10] As shown in Figure 3a, IPVs generate fewer free photogenerated carriers under indoor artificial light sources compared to sunlight. [11] These artificial indoor light sources include fluorescent lamps (FLs), incandescent bulbs, halogen bulbs, and LEDs, [12] for which their wavelengths fall approximately in the range 380-780 nm (Figure 3b). [13] In sunlight, traditional solar photovoltaic devices have a narrow bandgap.…”

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.

“…Nowadays, the record indoor PCE of PSCs has exceeded 40 % (under 1000 lux), which far exceeds other types of PV cells. [14][15][16][17] However, the drawbacks such as toxicity of lead (Pb) and poor stability of perovskite active layer limit their commercialization aspects. [18,19] Dye-sensitized photovoltaic cells (DSPVs) have been shown to be more effective in ambient light conditions.…”

“…Among these, PSCs exhibit great potential for high indoor efficiency devices due to the desirable optoelectronics properties such as tunable bandgap (1.2 eV to 3.5 eV), high absorption coefficients (10 5 cm −1 ), and small exciton binding energy (<100 meV). Nowadays, the record indoor PCE of PSCs has exceeded 40 % (under 1000 lux), which far exceeds other types of PV cells [14–17] .

Dye‐sensitized solar cells (DSSCs) are a feasible alternative to traditional silicon‐based solar cells because of their low cost, eco‐friendliness, flexibility, and acceptable device efficiency. In recent years, solid‐state DSSCs (ss‐DSSCs) have garnered much interest as they can overcome the leakage and evaporation issues of liquid electrolyte systems. However, the poor morphology of solid electrolytes and their interface with photoanodes can minimize the device performance. The photosensitizer/dye is a critical component of ss‐DSSCs and plays a vital role in the device‘s overall performance. In this review, we summarize recent developments and performance of photosensitizers, including mono‐ and co‐sensitization of ruthenium, porphyrin, and metal‐free organic dyes under 1 sun and ambient/artificial light conditions. We also discuss the various requirements that efficient photosensitizers should satisfy and provide an overview of their historical development over the years.

A robust perovskite‐buried interface is pivotal for achieving high‐performance flexible indoor photovoltaics as it significantly influences charge transport and extraction efficiency. Herein, we introduce a molecular bridge strategy utilizing sodium 2‐cyanoacetate (SZC) additive at the perovskite‐buried interface to simultaneously achieve in situ passivation of interfacial defects and bottom‐up crystallization modulation, resulting in high performance flexible indoor photovoltaic applications. Supported by both theoretical calculations and experimental evidences, we illustrate how SZCs serve as molecular bridges, establishing robust bonds between SnO2 transport layer and perovskite, mitigating oxygen vacancy defects and under‐coordinated Pb defects at interface during flexible fabrication. This, in turn, enhances interfacial energy level alignment and facilitates efficient carrier transport. Moreover, our in situ investigation of perovskite crystallization dynamics reveals bottom‐up crystallization modulation, extending perovskite growth at the buried interface and influencing subsequent surface recrystallization. This results in larger crystalline grains and improved lattice strain of the perovskite during flexible fabrication. Finally, the optimized flexible solar cells achieve an impressive efficiency exceeding 41% at 1000 lux, with a fill factor as high as 84.32%. The concept of the molecular bridge represents a significant advancement in enhancing the performance of perovskite‐based flexible indoor photovoltaics for the upcoming era of the Internet of Things (IoT ).This article is protected by copyright.
