Scientists from the University of Grenoble Alps, together with colleagues from the University of Pablo de Olavide, have created solar panels that efficiently generate electricity, and can also change the amount of transmitted light depending on its intensity. Information about the development is published in the journal Nature Energy.
Researchers have developed a dye that changes color when exposed to light.
In 2014, we worked on the creation of organic dyes in order to apply them in solar panels (DSSC) with Solaronix, to create integrated photovoltaic cells. One of our developments was installed in the facade of the EPFL conference center.

New solar panels are both energy-efficient and transparent, so they can be placed on windows. The color of the panel may change several times during the day. This feature allows you to collect solar energy during the day and filter less light that passes through the panels when evening or early morning arrives.
Researchers determined that the transparency of new batteries ranged from 60% to 27%, depending on the intensity of sunlight. Transparency decreases during bright light and rises in the dark. Thanks to this, the efficiency of the panels increased by 4.17%.
