China National Petroleum Corporation has developed a high-efficiency inverted perovskite solar cell with a power conversion efficiency of 25.05%, validated by the Shanghai Institute of Microsystem and Information Technology. This cell utilizes an inverted architecture and interface molecules to enhance stability and boost open-circuit voltage. CNPC plans to integrate this technology with traditional silicon cells to lower the cost of energy production. They are set to establish a pilot line in 2026 and a mass production facility in 2028, aiming to achieve renewable energy capacity on par with their oil and gas output by 2035.
