A research team hailing from Nanjing Tech University has ingeniously crafted a perovskite photovoltaic device, utilizing the 'all-vacuum thermal evaporation' method. This device, boasting an area of a mere 0.066 square centimeters, has attained an impressive photoelectric conversion efficiency of up to 25.19%, marking a new benchmark in the field. Notably, the device's performance sustained above 95% of its initial efficiency even after enduring continuous operation exceeding 1,000 hours. Furthermore, the efficiency of a larger, 1-square-centimeter variant of the device soared to 23.38%, underscoring its substantial promise for industrial applications. The pertinent research outcomes have been duly published in the esteemed journal Nature Photonics.
