“…The considerably high fill factors, FF = 68%, found for x = 1.5 compared to FF = 58% for x = 0 indicate also a better film quality of the deposited PIM films (Figure S4). In fact, the series resistance ( R S ) is 2.2 times lower, while the shunt resistance ( R SH ) is 3 times higher (Figure c). , SEM images confirm this picture, showing that the coverage of the PIM over the mesoporous TiO 2 was more extended (top view, Figure S4), and a significant beneficial capping layer of PIM was present for the mixed cation stack that was missing in the full Cs sample (cross-section, Figure d). , The fact that the V oc is 0.62 V for both x = 0 and x = 1.5 was related to an unchanged optical band gap ( E g ), which was obtained from Tauc plots (Figure S6), that was found to be ∼2.1 eV. This value aligns with the E g of layered Cs 3 Sb 2 I 9 (2.09 eV) and Cs 2 .…”

Perovskite-inspired materials (PIMs) have come to the fore recently because they aim to solve a main issue with perovskite technology, that of the potential toxicity of lead (Pb), as well as offer alternatives to tin (Sn)based perovskites, which are unstable. First, we introduced two cations in the precursor mixture, which improved power conversion efficiencies (PCE = 1.5%) of antimony (Sb)-based MA 1.5 Cs 1.5 Sb 2 I 3 Cl 6 solar cells by 81% compared to conventional Cs-only counterparts. ISOS-D-1 stability was also boosted by 60%, with a loss of only 10% after ∼1800 h of aging in the air. Stability over this many hours, accompanied by thermal durability of hundreds of hours at high temperatures of 85 °C in the air (ISOS-D-2), for these PIMs, also enabled us to carry out all three scalable P1, P2, and P3 laser patterning steps in air and demonstrate the first solar module (PCE = 1.2%) made with any kind of PIM.

Perovskite technology has shown impressive improvement in the last decade. Here, the first global positioning system (GPS)-perovskite-powered application is showcased by integrating flexible perovskite modules (fPSMs) onto an animal tracking collar for powering the Internet of Things (IoT) device that monitors wildlife bison to preserve the species and its habitat. A prototype of a solar-powered collar was designed to be more optimal for monitoring ample wildlife than commercially available asset-tracking devices, so it can provide necessary data to successfully introduce bison to new habitats. The fPSM were fabricated on a plastic substrate and connected in series configuration to generate power of 400 mW. A robust packaging with polycarbonate sheets and mechanical rivets was realized to withstand harsh environmental conditions, validated by conducting scratch and bending tests. The electronics and software system were optimized for ultra-low power mode operation, consuming only 1.9 mWh, which is 200 times less than the energy generated by our modules. The packaged modules in the outdoor testing setup retained over 30% of their initial power conversion efficiency (PCE) and power after 350 days (8400 h), giving still 60 times more power than necessary over ∼1 year of operational condition.

An all‐flexible self‐powering unit, combining a flexible perovskite solar mini‐module for energy conversion and ultra‐flexible screen‐printed interdigitated carbon supercapacitors on paper for energy storage, is designed and developed. Through a hybrid bifurcated structure, the supercapacitors are connected in series and neatly layered on a paper substrate with the perovskite solar mini‐module strategically placed on top for seamless integration. The photosupercapacitor quickly reaches saturated voltage under various light intensities (1 sun, 1000 lx, 500 lx, and 200 lx) and displays a self‐discharge time of over 2 minutes. It delivers peak overall and storage efficiencies of 2.8% and 23%, respectively, and exhibits an extensive potential window of 3.8 V, making it a prominent choice for real time applications in electronic systems. In a nutshell, the inherent flexibility of both the solar module and the storage system, coupled with the space‐saving design, and the extensive potential window of the hybrid photosupercapacitor paves the way for implementation in portable and wearable electronics operating in indoor environments, ushering a new era of more versatile and adaptable energy solutions.
