Buildings are among the largest energy consumers globally, with their energy demand and consumption patterns significantly influencing national energy systems and climate goals. Addressing these demands necessitates energy-efficient designs, policy interventions, and technological innovation to align consumption with climate objectives. Glass building facades have become prevalent in modern architecture, with the Lever House in New York City remaining a seminal example of the all-glass building movement. However, the inherently poor thermal properties of glass contribute to increased energy consumption. Consequently, numerous window technologies, such as photovoltaic (PV) windows, have emerged in recent decades to reconcile highly glazed buildings with lower energy usage. Perovskite solar cells (PSCs), which have recently achieved remarkable power conversion efficiencies (PCEs) of up to 27%, are optimal candidates for BIPV applications due to their tunable band gap, enabling their utilization in various sectors. This research study focuses on the exploration of wide band gap PSCs developed in a fully semitransparent configuration and their potential application in diverse fields, leveraging their semitransparency and aesthetic value. Starting with hybrid halide perovskites, devices exhibiting significant light transmission, reaching up to 70%, were investigated. Notably, FaPbBr3 achieved an impressive PCE of 8% with a remarkable VOC of up to 1.7 V [1], while also demonstrating suitability for blade coating on glass [2] and plastic substrates, paving the way for large-scale production. Furthermore, a fully inorganic perovskite, CsPbBr3, was scrutinized to stabilize its α-phase [3]. Finally, a lead-free, all-inorganic wide band gap perovskite solar cell, Cs2AgBiBr6, was successfully fabricated, maintaining high transparency and achieving 8% efficiency under low light illumination [4]. Ultimately, this research successfully demonstrated the integration of solar modules into a conventional window, realizing a 1 m² building-integrated photovoltaic (BIPV) demonstrator.
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.
