Kanazawa’s all-organic solar cells hit record 8.7% efficiency

Kanazawa University, headquartered in Japan and focused on sustainable technology research, has achieved 8.7% efficiency in all-organic solar cells on PET substrates. Kanazawa University has said that its team has developed organic electrodes with high conductivity, eliminating the need for acid doping or high-temperature treatment. According to Kanazawa University, a lamination method for the top electrode has preserved the integrity of the underlying layers and has improved overall device performance. Kanazawa University has reported achieving 8.6% efficiency using bioplastic substrates, showing that biodegradable materials are practical for solar applications. The university has stated that this advancement is an important step toward developing efficient, sustainable alternatives in photovoltaic technology.
