IMPRESSIVE’s main objective is to develop photovoltaic (PV) cells converting selectively UV & NIR part of the light excluding the visible range to reach colourless and fully transparent devices. To reach this ground-breaking objective, the approach is based on hybrid tandem UV-perovskite solar cell and NIR-dye-sensitized solar cell.

This innovative technology, based on a under-filing patent and recent breakthrough in perovskite absorbers, is expected to meet the objectives of full transparency and 14% Power Conversion Efficiency with a lifetime over 25 years.
