Descripción del proyecto
Nuevas celdas fotovoltaicas con absorción y transmisión ajustables
En el ámbito de las nuevas tecnologías fotovoltaicas, las celdas solares sensibilizadas por colorante (DSSC, por sus siglas en inglés) no solo constituyen una solución rentable prometedora, sino que además ofrecen estabilidad y semitransparencia, una característica innovadora. Con todo, dicha solución requiere un desarrollo ulterior. Las DSSC tienen infinidad de usos, desde en edificios y vehículos hasta en dispositivos electrónicos portátiles. El proyecto PISCO trabajará sobre la base de una propuesta de 2017 realizada por el investigador principal para combinar propiedades fotocromáticas y fotovoltaicas. Esto permitirá desarrollar celdas fotovoltaicas que pueden autoajustar tanto su absorción, en función de las condiciones meteorológicas, como su transmisión óptica. PISCO diseñará nuevos colorantes fotocromáticos altamente estables y, seguidamente, los evaluará en dispositivos. Finalmente, demostrará su potencial en aplicaciones de mercado. Las tecnologías innovadoras del proyecto favorecerán la energía solar tenga una mayor cuota en la producción energética europea.
Objetivo
Solar Solar energy is an unlimited renewable source of energy but its contribution to European energy production is still minor. It is therefore urgent to develop innovative photovoltaic (PV) technologies and products, and to implement them massively. Among emerging photovoltaics, Dye-Sensitized Solar Cells (DSSCs) are competitive in terms of efficiency, cost, and more importantly stability. They can be made semi-transparent which is an appealing feature for building or automobile integrated photovoltaics. But to be efficient, they have to harvest a maximum of photons from the sun, thus the best-performing DSSCs cannot show a good transparency which impedes their use as windows.
In 2017, I proposed a new concept to combine photochromism and photovoltaic, leading for the first time to efficient semi-transparent solar cells showing variable and self-adjustable optical transmission. These cells can simultaneously adapt their absorption depending on the weather conditions and produce electricity.
Starting from this result, PISCO will widely explore this exciting concept and provide a breakthrough in photovoltaics by developing a novel class of multifunctional solar cells that could be massively integrated in buildings, automotive, or mobile electronics.
The main objectives of PISCO are:
1) Design and synthesis of novel photochromic dyes with optimized optoelectronic properties and high stability.
2) Integration of these molecules in devices using methodologies to enable fundamental studies, to fully understand what factors are governing the photochromic behaviour, the generation of electrical power, and the interplay between them.
3) Inspired by the most relevant and recent concepts in the field, to develop robust and efficient photochromic solar cells and modules.
PISCO will provide the step change expected in photovoltaics, it will change our conceit of optical properties of solar cells by providing a ground-breaking technology with widen potential applications.
