제목 Tailoring Chemical and Morphological Properties of Graphene Oxide via γ-ray irradiation for Efficient Perovskite Solar Cells.
초록 Morphology controlled graphene oxide (GO) was prepared by irradiating aqueous GO by γ-ray and it was incorporated into PEDOT:PSS to fabricate high performance hole transport layer for efficient perovskite solar cells. γ-ray irradiation on the aqueous GO induced oxidation on the GO particles, while transforming each large particle into smaller particles. The structural modification of GO enhanced the distribution of the particles in PEDOT:PSS layer, which resulted in enhanced hole mobility, and contributed to improved crystallinity of the perovskite layer. The combined effect of enhanced hole mobility and the perovskite’s crystallinity lead to the improved electrical parameters and power conversion efficiency of the devices.
