A photovoltiac (PV) device that can change its color state has the potential to open up new opportunites and markets in building integrated PV. The development of smart PV windows can improve the energy performance of buildings with large glass facades and provide unique opportunites for occupant comfort. However, designing such multi-functional devices remains a significant challenge. This work will cover some of the different approaches that researchers have used to attack this problem, including chromogenic organic dyes and halide perovskite semiconducotrs. For halide perovskites, both the applicability of the perovskite to non-perovskite phase change and solvatochromism (color change in response to solvent intercalation-deintercalation) will be discussed, including demonstrations of initial work centered on both of these color change mechanisms and steps taken to address the key hurdles for each. Specifically, someinitial investigations on the rate of the perovskite to non-perovskite phase change will be presented in the context of developing this mechanism into a workable device. Secondly, work will present the prospects on designing 2D halide perovskites for more robust solvatochromic materials. This work will provide an improved understanding of the opportunities and challenges for different mechanisms for color-changing photovoltaic window operation and provide pathways forward to make windows into multifunctional components of future buildings.

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.
