Among emerging photovoltaic technologies, Dye-Sensitized Solar Cells (DSSC) represent a promising and appealing class of solar cells. In the last years, they have attained quite high efficiencies and stability, and they have demonstrated their potential to convert energy under non-ideal operating environments, including indoor. [1-2] They can be fabricated using low-cost manufacturing process and materials. More interestingly, these solar cells can be colourful and semi-transparent, which makes them appealing for use in Building-Integrated Photovoltaics (BIPV). [3-4]
However, when developing semi-transparent DSSCs, a trade-off has to be found between transparency and efficiency. Current state-of-the-art only allow for the fabrication of solar cells showing an optical transmission that is fixed during the fabrication process. For the development of smart photovoltaic windows and their massive integration in buildings, variable and self-adaptable optical properties would be very valuable.
To tackle this challenge, we recently proposed a new approach based on the development of photochromic sensitizers. In this communication, we will present our strategy to prepare photochromic dyes for use in DSSCs. We will discuss the structure-properties relationships of these photochromic molecules and we will show how they can be used to develop a new generation of functional solar cells capable to change their colour, self-adjust their transparency and their photovoltaic energy conversion depending on the daylight intensity. [5]
We will also discuss the factors influencing the photochromic behaviour and the photovoltaic properties of this new class of dyes in device configuration.

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.
