Problems solved by technology

In recent years, as researchers use new non-fullerene acceptor materials to increase the efficiency of laboratory cells to more than 15%, and continuously improve the preparation process of large-area cells, the competitiveness of large-area organic solar cells using mature thin-film technology is increasing. Gradually improving, but the challenge of moving from the laboratory to the manufacturing plant is still the biggest obstacle to marketization
