摘要: Since its inception in 1995, significant advances the field of bulk heterojunction (BHJ) solar cells have been made and polymeric semiconductors are now considered to be one most promising ways lower cost energy generated by cells. Power conversion efficiencies (PCEs) reaching threshold values for commercialisation (9.2% single-layer BHJ 10.6% tandem devices). PCDTBT, a carbazole-based copolymer, is among efficient, stable low-cost materials with high open-circuit voltage (Voc ∼ 0.90 V), power efficiency 7.5% estimated lifetime 7 years. PCDTBT surpasses performance P3HT (the studied material until now) as new benchmarks development highly efficient
