Building Integrated Photovoltaics (BIPV) envisages the replacement of traditional architectural elements with materials incorporating solar modules and represents one of the current most attractive research topic in the field of PV technologies. In this context, perovskite solar cells (PSCs) have attracted huge attention owing to their large absorption coefficient as well as color tunability.
Here, we report on a class of mixed halide perovskite named MAPb(Br1-xClx)3 which have been only marginally investigated in the literature for the development of transparent solar cells. Specifically, we combine electro-optical modeling and experimental results to design transparent PV (TPV) devices (cells and modules) maximizing at the same time key parameters such as Power Conversion Efficiency (PCE), Average Visible Transmittance (AVT) and Light Utilization Efficiency (LUE). The simulated results have been confirmed by fabricating devices showing state-of-art performances. Importantly, we obtained values up to 70% in terms of AVT and 4.3 % of LUE - among the highest reported so far. Moreover, light and thermal stability tests were performed on the most promising mixed compositions (0, 0.04 and 0.13 xCl), obtaining good results. Finally, we demonstrated the up-scaling process with the fabrication of mini-modules. Crucial aspects were evaluated such like the uniformity of the deposition of the entire device stack on larger substrate (5.7x5.7cm2 and 10x10cm2) and the P1-P2-P3 laser ablations. Only for 48.8 cm2-sized modules we observe a slight drop in terms of PCE if compared to the cells.
We believe that this oral presentation would be of great interest for a broad audience.

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.
