Outline of Final Research Achievements

Conjugated polymer-based organic solar cells have gained increasing attention as an inexpensive source of renewable energy owing to their unique advantages, which include high throughput and large-area production with low-cost printing processes. In this research, all-polymer solar cells based on a blend film of two types of conjugated polymers acting as a p-type and n-type semiconductors have been developed. Optimization of the blend morphology and fine tuning of the polymer semiconducting properties have increased the power conversion efficiencies of the device from 2.0 to 6.7%.
