Fabrication of Organic/Inorganic Silicon Hybrid Solar Cell Based on Pedot: Pss/Pc71bm Doped at Different Concentrations of Rubrene

Polymer-based solar cells (PSCs) have drawn great interest in recent years because PSCs have potential advantages over conventional organic/inorganic silicon hybrid solar cells. It dramatically reduced material/production cost, compact substrates, and lightweight finished solar cells. In light of increasing interest here we investigated the effect of the Rubrene in PEDOT:PC71BM hole transport layer for the bulk heterojunction framework with solution-processable fictionalized the productive film of organic solar cells. Cells were based on a mixture of poly (3, 4-ethylene dioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) and [6,6]-phenyl C71-butyric acid methyl ester (PC71BM). The Rubrene has blended with PEDOT: PSS/PC71BM mixture (1:0.6 w/w) at 6, 9, 12, and 15wt% ratios, while the structure of the device was Si/PEDOT: PSS / PC71BM: Rubrene: DMSO/Ag. The Ag was used as an electrode and accumulated in a vacuum-free process by drop-casting. The best results were achieved with 6 wt% of Rubrene: DMSO with a 13.97mA.cm 2 , 514.80mV, 40.97 and 2.948% short-circuit current density ( J sc ), an open-circuit it volt ( V oc ), fill factor (FF), and power conversion efficiency (PCE) respectively were touched. The results found that the observed PCE is more significant than earlier reports utilizing similar materials and Rubrene in the active layer. The Rubrene can be well distributed with the PC71BM to create a homogeneous solution that might improve the excitation energy's disconnection and the electron species' transit clear path.
