“…Responsivity is an important characteristic of PDs, and it provides information about the ratio of the generated photocurrent to the power of incoming light. It is calculated from EQE using the following relation − R = normalE normalQ normalE q h v Here, q is the elementary charge, h is Planck’s constant, and v is the frequency of incident light. The responsivity spectra of the PFBPPD for bottom- and top-side illuminations are shown in Figure c.…”

Perovskite photodetectors (PPDs) may have an exciting commercial impact owing to their excellent device performance and affordability. However, to enhance their competitiveness in the industry, a few technological aspects of PPDs, such as scalability, robustness, weight, and semitransparency, still require further improvement. This work focuses on the scalable fabrication of PPDs on plastic substrates using slot-die coating techniques employing dielectric−metal−dielectric (DMD) transparent top contacts. The DMD provides the devices with a bifaciality feature. The device's functional layers are deposited using the slot-die coating technique, whereas the top DMD contacts are deposited using thermal evaporation. The fabricated devices demonstrate remarkable performance and a high bifaciality factor in the visible spectrum. For bottom-side illumination, the responsivity and detectivity of devices have excellent values reaching 0.2 A W −1 and 2 × 10 11 Jones, respectively. As for top-side illumination, they are as high as 0.15 A W −1 and 1.47 × 10 11 Jones, respectively. The overall bifaciality factor in devices for the visible spectrum is around 65% and can reach values of up to 78% in the 610−650 nm range. Furthermore, the fabricated devices without any encapsulation in air maintain around 28% of their initial performance after 50 bendings.

Copper oxide is one of the original semiconductor materials employed for solar cells in the early 19th century before Silicon solar cells became popular due to their abundant availability, and eco‐friendly nature. The optoelectronic parameters signify its huge potential in solar cell devices, though it's far from the theoretically predicted performance, provides tremendous scope to improve the solar cell performance by forming different heterojunctions. In this study, we investigated the copper oxide's (CuO) potential as an active layer in thin‐film solar cells theoretically with a new structure consisting of a Glass/ITO/Graphite/CuO/Ni. Furthermore, the charge carrier's generation rate and theoretical thresholds for photovoltaic device efficiency were determined for varying active layer thicknesses by employing a normalized light intensity equivalent to that of the AM1.5 spectrum. The optimized performance of the simulated structure by considering realistic optical parameters of the solar cell was ~24%, obtained for the 500 nm CuO films. The performed theoretical work can help to employ CuO and boost the performance of solar cells experimentally.

This study investigates the impact of proton irradiation on perovskite devices fabricated fully through vacuum deposition. Exposure to irradiation induces changes in both electrical and optical properties. The analysis reveals that the main factors influencing the observed performance changes in solar cells are a significant reduction in shunt resistance and a minor increase in series resistance, with minimal alterations in recombination dynamics. Remarkably, the devices maintain promising photodetector characteristics both before and after proton irradiation, particularly in a self-powered mode without a reverse bias. These findings provide valuable insights into the resilience of vacuum-deposited perovskite devices against ionizing radiation, highlighting their potential for applications in radiation-prone environments, such as the nuclear industry or space exploration.
