• Organic solar cells retain 93% power-conversion efficiency with new additive Devices usually achieve only 76% retention with a toxic additive after 180 hours of use. • A study conducted by Penn State University researchers has revealed that organic solar cells could be strengthened by adding a chemical additive, making them suitable for large-scale deployment and manufacturing. • The study was reported on the official university website on February 16. • Assistant Professor Nutifafa Doumon and doctoral candidate Souk Yoon “John” Kim, both from the Department of Materials Science and Engineering, led this experiment. • The paper was recognized in ACS Materials Au’s “2025 Rising Stars in Materials Science” issue, which will be published this month. • Manufacturing silicon solar panels consumes massive amounts of energy and requires the use of toxic chemicals, creating recycling challenges.
