| Popis: | Graphitic carbon nitride (g-C3N4) and silver (Ag) co-modified titanium (IV) oxide (TiO2) was developed and employed as electron transport layer (ETL) in organic solar cell (OSC) to improve electron extraction and transport. The morphological, optical and electrical properties of the ETL were investigated using X-ray diffraction, atomic force microscopy and photocurrent density-voltage measurement. The OSC exhibited maximum power conversion efficiency of 1.7% which is 30% and 13% higher than devices based on pristine TiO2 and g-C3N4/TiO2 nanocomposite, respectively. The enhancement of OSC performance was primarily ascribed to (1) smoother surface of ETL ensuring good interfacial adhesion between ETL and polymer layer, (2) enhanced light scattering effect and (3) effective electron collection and suppressed recombination at ETL/polymer interface. |
