Mesoscopic dye-sensitized solar cells (DSCs) were invented in 1990s by Brian O'Regan and Michael Grätzel, taking on the latter's name—the world-famous Grätzel cells.
With this approach, the team was able to develop DSCs with a power conversion efficiency of 15.2% for the first time under standard global simulated sunlight, with long-term operational stability tested over 500 hours. By increasing the active area to 2.8 cm2, the power conversion efficiency spanned 28.4%—30.2% over a wide range of ambient light intensities along with outstanding stability.
