Narrow-bandgap perovskite solar cells have revolutionized photovoltaics, achieving remarkable power conversion efficiencies (PCE) up to 25%. However, their opaque and dark color has hindered their widespread adoption in building-integrated photovoltaic (BIPV) applications due to sustainability in our everyday surroundings. By manipulating the chemical composition of the perovskite materials, a new frontier of transparency in perovskite solar cells has been unlocked. By widening the bandgap of perovskite, reaching up 2.6 eV, researchers have successfully bridged the gap between transparency and efficiency. This breakthrough paves the way for a new generation of BIPVs that blend seamlessly into architectural designs while delivering substantial energy savings. By using a transparent conductive oxide as top electrode, three generation of wide-bandgap perovskite solar cells, hybrid halide perovskite (Ma+ and Fa+), inorganic halide (Cs+) and inorganic Pb-free perovskite have been studied and developed in a full-semitransparent stack with the aim to meet harmony between conversion efficiency and transparency. These devices exhibit impressive transmittances, reaching a staggering 70%. FaPbBr3 attained an impressive PCE of 8% with a remarkable VOC up to 1.7 V while also exhibiting suitability for blade coating on glass [1] and plastic substrates, paving the way for large-scale production. CsPbBr3, a fully inorganic perovskite, has been scrutinized in an attempt to bolster its α-phase, and a Pb-free Cs2AgBiBr6, holistic inorganic wide band gap perovskite solar cell has been successfully fabricated maintaining this high level of transparency reaching 8% at low light illumination. Furthermore, we are presenting for the first time a 25 cm2 module for a blade-coated, fully inorganic, lead-free perovskite-like material capable of powering electronic devices in the IoT field. This advancement eliminates concerns about the potential environmental impact of lead in perovskite structures. The development of wide-bandgap perovskite solar cells represents a significant leap forward in the field of photovoltaics. These transparent devices hold immense promise for seamlessly integrating solar energy into buildings, reducing our reliance on fossil fuels and promoting a sustainable future.
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.
