The impact of the Se addition and temperature during the selenization process on the composition, structural, morphological, vibrational, and optical properties of the Sb-Ge-Se layers is investigated. The coexistence of Sb₂Se₃ and GeSe₂ has been confirmed using various characterization techniques, including Grazing Incidence X-ray diffraction, Fourier Transform Infrared Spectroscopy, X-ray Photoelectron Spectroscopy and Raman spectroscopy. Additionally, Scanning Transmission Electron Microscopy has revealed Ge-enrichment regions surrounding the Sb₂Se₃ crystals. The composition of the co-evaporated film and final Ge content in the chalcogenide film govern the band gap energy, increasing from 1.41 to 1.83 eV. We present the inaugural operational SLG/Mo/Sb-Ge-Se/CdS/ZnO/ITO photovoltaic devices with a total efficiency of 1.34%. The primary factors limiting the device performance are the significant CdS diffusion into the active layer and the high defect density, as determined by Capacitance-Voltage and Drive-Level Capacitance Profiling.

However, the underwater (UW) environment remains largely unexplored. Below 50 m, the solar spectrum shifts dramatically, with only blue-green light (400–600 nm) available. Perovskite solar cells (PSCs), known for their high-power conversion efficiencies (PCEs) and tunable bandgaps, offer potential for this environment. Initially, simulations compared the intensity of the solar radiation based on three models, each based on a different water body, down to a depth of 10 m. The trend of maximum theoretical performance, ranging from 1.5 to 3 eV band gap, was analyzed with respect to depth. In this pioneering study, a wide bandgap PSC, based on FaPbBr₃, has been selected to operate underwater. Results were achieved through a complete in-house process encompassing fabrication, encapsulation, and underwater measurement. A 10-day saltwater submersion test of a damaged device confirmed minimal lead release, meeting stringent legal standards for lead in potable water. PV performance was evaluated UW, demonstrating an enhanced conversion efficiency within the first centimeters of water. This enhancement is due to water's optical and cooling properties.
