For halide perovskite solar cells (PSCs) to fulfill their vast potential for combining low-cost, high efficiency, and throughput production they must be scaled using a truly transformative method, such as roll-to-roll processing. Bringing this reality closer fruition, the present work demonstrates flexible with 18.1% power conversion efficiency on Willow Glass substrates. We highlight importance of transparent conductive oxide (TCO) layers device performance by studying various TCOs. While...
Energy conservation is crucial for sustainable growth. Electrochromic window devices, which regulate optical transmittance using light‐tunable materials like WO 3 , can significantly reduce both thermal and visual energy consumption in buildings. In this study, we developed solid‐state thin film‐based electrochromic room‐temperature sputtering. The film was grown through reactive sputtering of a tungsten target, resulting highly transparent films with structural properties well‐suitable...
Till now, BiVO4 has been extensively investigated for photoelectrochemical cell applications; however, the efficacy of in photodetector (PD) and photovoltaic field is still challenging due to its poor absorption ability, conductivity, high recombination rate.

Transparent photovoltaics (TPVs), a see-through energy production platform that allows visible light to pass while absorbing harmful ultraviolet light, is the backbone of invisible onsite power generation.
Transparent photovoltaics (TPVs) are crucial for developing next‐generation see‐through electronics. However, TPV devices (TPVDs) require wide‐bandgap materials that typically only responsive to short wavelength (ultraviolet, UV) lights rather than visible lights. Is it possible improve the performance by harvesting longer without degradation of transparency? It may be satisfied with function intermediate energy states, which can utilize lower photon (longer light) a two‐step transition. To...
In the quest of exploring ecofriendly energy solutions, transparent photovoltaics (TPVs) have emerged as a promising innovation.
