Inverted polymer solar cells (iPSCs) have been developed for the effective photovoltaic technology with the lightweight, low-cost process, and flexibility. To achieve the outstanding performance of iPSCs, zinc oxide (ZnO) and small molecules are mainly hybridized for solving the thickness tolerance problem. In this presentation, new small molecular eletrolyte (C6-E-OTs) was synthesized and hybridized into ZnO as an electron transport layer (ETL). The device based on hybridized ZnO with 10.0 wt. % of C6-E-OTs is optimum condition, which reached up to the high power conversion efficiency (PCE), 8.8 %. We fabricated three kind of devices, which are the devices with hybridized ZnO, ZnO/Interlayer, and hybridized ZnO/Interlayer. Moreover, the device with the structure of hybridized ZnO/Interlayer showed the highest PCE, 8.9 %. These results were proved through investigating enhanced short circuit current density (Jsc) and lower work function than pristine ZnO. |
