Abstract Semi‐transparent solar cells are emerging as promising devices for building integrated photovoltaics. However, regardless of the technology considered, optical transmission semi‐transparent is fixed during fabrication process, and hence, cannot adjust to variations in daylight or weather conditions. This becomes an issue when applications such photovoltaic windows envisioned. Previously, it has been reported that use photochromic naphthopyran dyes dye‐sensitized (DSSC) allows...
New benzothiadiazole-based dyes are synthesized, characterized and used for the fabrication of robust efficient solar cells mini-modules.
Photochromic dyes possess unique properties that can be exploited in different domains. Here, we investigate the potential of spiro-indoline naphthopyran and naphthoxazine photovoltaics.
Because they can be made semi-transparent, dye-sensitised solar cells (DSSCs) have great potential for glazing applications. Their photovoltaic performance and light transmission depend not only on the dye used, but also electrolyte contain. A few years ago, we introduced concept of with dynamic optical properties based use photochromic photosensitizers. These allow variable according to sunlight conditions, while producing electrical energy. We found that electrolytes commonly used in DSSCs...
Photochromic dye-sensitized solar cells (DSSCs) are novel semi-transparent photovoltaic devices that self-adjust their optical properties to the irradiation conditions, a feature makes them especially suitable for building integrated photovoltaics. These have already achieved efficiencies above 4%, and there multiple pathways improve performance. In this work, we conduct full characterization of DSSCs with photochromic dye NPI, combining electrical impedance spectroscopy (EIS)...
We recently demonstrated that diaryl-naphthopyran photochromic dyes are efficient for sensitization of TiO2 mesoporous electrodes, thus allowing the fabrication photo-chromo-voltaic cells can self-adapt their absorption light and generation electricity with intensity. Herein we report synthesis, characterisation two novel based on core i.e NPI-ThPh NPI-FuPh use in Dye Sensitized Solar Cells (DSSCs). Compared to our reference dye NPI, molecules only vary by nature spacer, a thiophene or...
Upcycling of polyethersulfone (PES), a high-performance polymer based on an aromatic-rich aryl-ether-based backbone, can advantageously yield both starting Bisphenol S (BPS) comonomer and valuable OLED derivatives, providing complete atom valorisation strategy for PES waste. Deprotonated selected amines proved particularly efficient at depolymerizing moderate temperatures (~ 120 °C). The recycled monomer yields validate the back-to-monomer chemical recycling method industrial compliance....
The development of hole transport materials (HTMs) is a prolific area research due to the application these in various technologies such as organic light-emitting diodes (OLEDs) or perovskite solar cells (PSCs). HTMs have notably played crucial role high-performance PSCs since devices, they not only ensure collection and holes counterelectrode but also play an important on device stability. In addition need for good properties be easy process, it paramount importance guarantee that their...

In this paper, we will present our approach to develop a new class of solar cells with dynamic optical properties. We have synthesized organic photosensitizers showing photochromic properties and incorporated them into dye-sensitized cells. obtained semi-transparent able self-adapt autonomously their light transmission energy production according daylight variations. discuss the synthesis photosensitizers, electronic properties, development mini-modules using them.
