Photovoltaic (PV) technologies are increasingly deployed beyond conventional terrestrial settings, where light intensity and spectral distribution deviate markedly from standard AM1.5G conditions[1]. Underwater environments represent a prime example, characterized by severe light attenuation, depth-dependent spectral narrowing, and a shift in demand toward low-power electronics rather than grid-scale generation[2]. Consequently, the core objective must shift from a singular pursuit of maximum terrestrial efficiency to identifying PV platforms that deliver reliable power under these aquatic constraints.
Moving beyond conventional device optimization, this study evaluates how perovskite compositions, optical responses, and architectures can be tailored to match the unique underwater spectrum[3]. Due to their exceptional visible-light absorption and intrinsic bandgap tunability, perovskites offer a strategic advantage in these spectrally selective environments over traditional PV technologies that were originally optimized for the full solar spectrum[4-5].
To bridge the gap between material properties and practical utility, we extend the investigation to field related application verification by coupling perovskite modules with energy storage and low-power submerged mnitor. Real-world aquatic testing validates the feasibility of these integrated units to drive functional, self-powered sensing platforms. Ultimately, this work establishes a design paradigm that prioritizes environmental compatibility and system integration over raw material records for next-generation photovoltaics.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
