Chinese solar manufacturer Trina Solar has achieved 22.61% efficiency on its p-type PERC cell based on a large-sized (243.23 cm2) boron-doped Cz-Si substrate - the highest so far for this size using a low-cost industrial process. The levels were officially verified by Germany’s Fraunhofer ISE CalLab, and beat Trina Solar's previous record of 21.1%. This is significant because it represents an important milestone in China’s push to become one of the world’s top 10 photovoltaic producers, with annual capacity expected to reach more than 100 GW by 2020.
