World's first perovskite solar roof tile developed, delivers energy efficiency of 12.4% A Dutch company has developed the ‘world’s first’ perovskite solar roof tile. Despite its curved shape, the solar roof tile module achieves an energy efficiency of 12.4%. Developed by researchers at TNO, the innovative material is the world’s first electrically functioning solar roof tile concept based on flexible perovskite solar cells.’ TNO claims that this is an important step towards better integrating solar energy into the built environment, creating more room for sustainable electricity generation without additional pressure on land or infrastructure. Roofs to generate sustainable electricity “This allows roofs and infrastructure to generate sustainable electricity without compromising on design or aesthetics,” said Roland Valckenborg, Senior Project Manager at TNO Solar. “This makes it an important step in the further development of solar energy in the built environment.” The perovskite solar module on flexible foil has been applied in collaboration with ASAT B.V. to a curved composite roof tile. Measurements show that bending the module onto the roof tile has only a limited effect on its performance. The individual modules achieved an energy efficiency of up to 13.8%. After installation on a curved roof tile, 12.4% efficiency was retained, according to a press release. The company also claimed that by... https://interestingengineering.com/energy/world-first-perovskite-solar-roof-tile
