“…It has been shown that in DSCs the efficiency increases as the illumination decreases from 10 -12 % in AM1.5G mode to values exceeding 20 % under diffuse artificial lighting (200 -1000 lx). Under similar conditions, PSCs demonstrate even more impressive results when the efficiency increases from ∼ 18 -20 % in AM1.5G mode to ∼ 30 % under 200 -1000 lx ambient lighting [51,53,54].…”

“…It was found that 10 % bromide-doped perovskite photoactive layers exhibit the best performance as a result of better crystallization and uniform surface that helped to form larger grains of perovskite with reduced defect concentrations, which suppressed carrier trapping and recombination and resulted in improved PSC performance [53]. As a result, under dim LED indoor illumination of 1000 lx, these types of PSCs have gained PCE of 34.5 % [54]. Actually, the result obtained demonstrates the appearance of the new indoor electronics.…”

“…The data obtained indicated that the efficiency for either PSCs or DSCs in outdoor conditions demonstrated an increase in conversion efficiency with a decrease in light intensity. The data available from the literature have shown great promise for the use of DSC-and PSC-based light energy SCs for highly efficient indoor operation under low-power artificial light sources with a relatively narrow spectral range [50,54]. Thus, increase in the efficiency and development of novel stable photoconverters based on DSC and PSC, optimized for indoor operation under diffuse artificial lighting, is a new and relevant problem for modern photovoltaics.…”

“…Development of double-sided SCs architectures for efficient indoor light harvesting opens a possibility to reach outstanding efficiencies. Bearing in mind that with the appropriate location of a PSC with more than 30 % efficiency [54], where low intensity diffuse lighting falls on the PSC surface from all sides, the efficiency of a double-sided photovoltaic device can be doubled, compared to the one-sided conventional scheme, and could reach the value of around 60 % efficiency per unit area.…”

“…To date, the world production of solar cells, can be conventionally divided into the following categories: solar modules of a large area for powerful solar power plants that generate network electricity, modules for distributed systems of local consumers, and small-sized systems to power portable electronic devices [54]. In turn, the latter category also includes SCs for low-power autonomous SC devices and systems (energy harvesting) for the application in the enclosed areas under low-intensity artificial lighting.…”

Energy harvesting technologies collect various forms of ambient energies such as heat, light, or vibrations to generate electricity at micro scales. [1,2] Provided that the wasted energy dissipated in the environment is ubiquitous, energy harvesters present the potential to be self-sustaining with an ideal infinite functioning lifetime. Therefore, they have been considered a potential alternative to the traditional battery-based energy solutions presently enforced to energize electronic consumer goods, the Internet of Things (IoT), or other distributed electronic-based ecosystems. [3,4] Since many of these electronic devices are typically located inside buildings, there is great potential for energizing them via integrating photovoltaics (PVs) that can harvest abundantly available ambient indoor light energy from LED, halogen, and FL lamps or other types of light sources. This promising approach can be used to achieve sustainability within portable electronic devices, as well as in advanced-distributed electronic environments. [3,[5][6][7][8][9] Keeping this motivation in mind, established silicon (Si) solar cell-based PV technologies have initially been deployed to harvest ambient light energy for energizing various low-powered electronic appliances such as calculators, digital thermometers, and electronic clocks. [10] However, the low power conversion efficiency under lowlight conditions, combined with high production costs have limited their widespread use in indoor applications. [7,8,11] In contrast to Si-based PVs, third-generation-based solar cell technologies such as organic solar cells (OSC) or dye-sensitized solar cells (DSSC) have shown striking performance with higher conversion efficiencies when tested under indoor light conditions. [12][13][14][15][16][17][18][19] Similar to these third-generation-based PV technologies, the escalating conversion efficiencies of perovskite solar cells (PSCs) under standard illumination conditions [20,21] consequently motivated research labs worldwide to also examine their PV performance under various ambient light intensities. [6,[22][23][24][25][26] As expected, the striking conversion efficiencies of PSCs achieved in recent years (Table 1) under these ambient light intensity conditions provide preliminary evidence for considering them as another potential light-harvesting solution for energizing

Halide perovskite‐based photovoltaic (PV) devices have recently emerged for low energy consumption electronic devices such as Internet of Things (IoT). In this work, an effective strategy to form a hole‐selective layer using phenethylammonium iodide (PEAI) salt is presented that demonstrates unprecedently high open‐circuit voltage of 0.9 V with 18 µW cm−2 under 200 lux (cool white light‐emitting diodes). An appropriate post‐deposited amount of PEAI (2 mg) strongly interacts with the perovskite surface forming a conformal coating of PEAI on the perovskite film surface, which improves the crystallinity and absorption of the film. Here, Kelvin probe force microscopy results indicate the diminished potential difference across the grain boundaries and grain interiors after the PEAI deposition, constructing an electrically and chemically homogeneous surface. Also, the surface becomes more p‐type with a downshift of a valence band maximum, confirmed by ultraviolet photoelectron spectroscopy measurement, facilitating the transport of holes to the hole transport layer (HTL). The hole‐selective layer‐deposited devices exhibit reduced hysteresis in light current density–voltage curves and maintain steadily high fill factor across the different light intensities (200–1000 lux). This work highlights the importance of the HTL/perovskite interface that prepares the indoor halide perovskite PV devices for powering IoT device.
