The potential to continuously adjust the band gap of halide perovskite materials across a wide range from near-infrared to near-ultraviolet wavelengths presents an opportunity to develop semitransparent perovskite solar cells and modules that offer high visual transmittance. By optimizing the band gap of perovskite cells, it is possible to construct a tandem configuration with near-infrared organic solar cells to improve efficiency without compromising the average visual transmittance (AVT). Numerical simulations indicate that an optimized tandem architecture utilizing suitable photonic crystals and materials can achieve a power conversion efficiency of 15% with an AVT of 50%.[1] The EU CITYSOLAR consortium has devised specific strategies to achieve this objective, including material optimization for both perovskite and organic solar cells, as well as light management and new characterization strategies.[2] In this presentation, I will highlight the efforts of the consortium and their progress in surpassing the state of the art showing several strategies ranging from solution processes to physical deposition for the fabrication of see-through photovoltaics. Such endeavors have expanded beyond solar cells and include module-level developments. With respect to perovskite solar cell (PSC) modules, a low-temperature, full blade-coating technique has been devised in air to deposit semi-transparent FAPbBr3-based perovskite modules on 300 cm2 substrates.[3]

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.
