As Europe’s transparent solar panel market swells, Swiss scientists have set a new efficiency record for the technology. This could lead the way to energy-generating windows that power up our homes and devices. Also known as Grätzel cells, dye-sensitised solar cells (DSCs) are a type of low-cost solar cell that use photosensitized dye to convert visible light into electricity. Previous versions of DSCs have been reliant on direct sunlight, but a team of researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have found a way to make transparent photosensitizers that can absorb light across the entire visible light spectrum,…
