Effect of side chain structure on the photovoltaic properties of BDTF-based polymers

Organic solar cells (OSCs) are increasingly valued for their flexibility, lightweight nature, cost-effectiveness, and scalability for renewable energy production. Enhancing OSC efficiency involves designing new donor polymers through precise monomers design and optimized side-chain structures. This...

Summary:Organic solar cells (OSCs) are increasingly valued for their flexibility, lightweight nature, cost-effectiveness, and scalability for renewable energy production. Enhancing OSC efficiency involves designing new donor polymers through precise monomers design and optimized side-chain structures. This study examines an alkyl branching strategy using ethyl hexyl thiophene-dione (TIND-DEHT) in fluorinated benzodithiophene (BDTF)-based polymers, compared to linear octyl thiophene-dione (TIND-DOT-BDTF). In inverted OSCs, TIND-DEHT-BDTF achieves a higher power conversion efficiency (PCE) of 7.13%, surpassing TIND-DOT-BDTF's 6.55%. These findings emphasize the significant potential of side-chain branch engineering in improving molecular and photovoltaic performance in OSCs.
