Transparent 'Grätzel' solar cells achieve a new efficiency record
Mesoscopic dye-sensitized solar cells (DSCs) often known as the renowned Grätzel cells were developed 32 years ago by Brian ORegan and Michael Grätzel. DSCs use photosensitizers to turn light into electricity.
Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have discovered a way to create transparent photosensitizers molecules that can be activated by light and adsorb light across the entire visible light spectrum. Previous versions of DSCs were largely dependent on direct sunlight.
