“…Regarding the ideal E G value for iPVs, there is no concrete answer, since the optimum semiconductor E G depends on the spectrum of the incident radiation. [ 48 ] Therefore, since the white light LED bulbs are already commonly applied for indoor lighting, answers were mostly given regarding this kind of lighting.…”

“…[ 49 ] For instance, a theoretical maximum efficiency of up to 52% holds for iPV devices with an optimal E G of 1.8 eV under 1000 Lux cool white LEDs and 53.6% for warm white LED with an optimum E G of 1.88 eV. [ 48 ] As an example of the difference among the S‐Q curves per bandgap energy for various illumination types, the respective curves of AM1.5G and of a TL5 lamp under 1000 Lux are shown in Figure 4 a. Besides, in Figure 4b, a comparison between AM1.5G and FL, halogen lamps, RGB white LED, phosphor white LED, as well as, sodium discharge lamps is presented thus highlighting the difference in their S‐Q curves.…”

The high‐power conversion efficiency of flexible perovskite photovoltaics (PPV) at low light environment and their low‐cost manufacturing processes, render PPV superior to conventional rigid photovoltaics targeting indoor applications. However, various parameters related to materials, architecture, processing, and indoor characterization need to be optimized further toward improving indoor PPV (iPPV) efficiency, stability, and ecotoxicity. This work provides an overview of the recent progress, trends, and challenges in the field and suggests a holistic approach toward a viable design and integration of iPPVs into Internet of Things (IoT) platforms without any compromise on safety and cost effectiveness. The key impact of selecting proper materials and fabrication techniques, as well as optimizing the active area and architecture is described. Certain peculiarities of the indoor lighting conditions are discussed that can be addressed by proper simulation tools, including the understanding of the charge‐transfer mechanism, the diversification of the lamp types, as well as identifying the requirements for the production, standardization, and installation of iPPVs associated with IoT devices. A multidimensional engineering approach that considers aspects of architecture, light technology, load specifications, materials, processing, safety and cost, is proposed as a path toward accelerating iPPV market uptake for households, businesses, wearables and Industry 4.0 applications.
