“…GO, a two-dimensional carbon material, has also been investigated to modified PEDOT:PSS as hole-transport materials in different OSCs. The Oleyamine-functionalized GO/PEDOT:PSS layer on PBDB-T:ITIC [ 317 ], PEDOT:PSS treated with GO layers on PTB7:PC 71 BM devices [ 318 ], on P3HT:PC 60 BM devices [ 319 ], on P3HT:PCBM devices [ 320 ], on inverted P3HT:PCBM OSCs [ 321 ], on inverted P3HT:PC 71 BM OSCs [ 322 ], and on reduced GO-germanium QDs modified PEDOT:PSS on P3HT:PCBM [ 323 ]. Raj et al reported the fabrication of PTB7:PC 70 BM-based OSCs with PEDOT:PSS:GO, resulting in enhanced PCE of 7.68% [ 324 ].…”

Global energy demand is increasing; thus, emerging renewable energy sources, such as organic solar cells (OSCs), are fundamental to mitigate the negative effects of fuel consumption. Within OSC’s advancements, the development of efficient and stable interface materials is essential to achieve high performance, long-term stability, low costs, and broader applicability. Inorganic and nanocarbon-based materials show a suitable work function, tunable optical/electronic properties, stability to the presence of moisture, and facile solution processing, while organic conducting polymers and small molecules have some advantages such as fast and low-cost production, solution process, low energy payback time, light weight, and less adverse environmental impact, making them attractive as hole transporting layers (HTLs) for OSCs. This review looked at the recent progress in metal oxides, metal sulfides, nanocarbon materials, conducting polymers, and small organic molecules as HTLs in OSCs over the past five years. The endeavors in research and technology have optimized the preparation and deposition methods of HTLs. Strategies of doping, composite/hybrid formation, and modifications have also tuned the optical/electrical properties of these materials as HTLs to obtain efficient and stable OSCs. We highlighted the impact of structure, composition, and processing conditions of inorganic and organic materials as HTLs in conventional and inverted OSCs.

“…There are many alternatives to PEDOT:PSS, but graphene oxide (GO) is utilized as its alternative in this simulation. All simulation parameters for HTM layers in the structure are carefully chosen from the reported experimental data and different works available in the literature [ 35 , 36 , 37 , 40 , 41 , 66 , 67 ].…”

“…Moreover, PEDOT:PSS/GO exhibits a PCE of 12.34%—nearly equal to PEDOT:PSS—but their current density values differ. PEDOT:PSS/GO has a slightly different J-V curve than the other HTMs because it has distinct values for charge carrier mobilities, conductivity, and bandgap [ 35 , 67 ]. Due to this, it may interact differently with the light-harvesting layer.…”

Performance Analysis and Optimization of a PBDB-T:ITIC Based Organic Solar Cell Using Graphene Oxide as the Hole Transport Layer

et al. 2022

The hole transport layer (HTL) in organic solar cells (OSCs) plays an imperative role in boosting the cell’s performance. PEDOT: PSS is a conventional HTL used in OSCs owing to its high design cost and instability issues. It can be replaced with graphene oxide to increase the cell performance by overcoming instability issues. Graphene oxide (GO) has gained popularity in recent years for its practical use in solar energy due to its remarkable mechanical, electrical, thermal, and optical properties. This work uses SCAPS-1D to examine the results of graphene oxide (GO)-based organic solar cells by giving a comparison between the performance of absorber layers and a GO-based HTL to see which absorber material interacts more strongly with GO. The absorber layer PBDB-T:ITIC paired with GO as HTL outperforms the other absorber layers due to its better optical and electrical characteristics. Numerical simulations are performed within the SCAPS software at various absorber layer thicknesses, defect densities, and doping values to assess the influence on device performance and efficiency. After cell optimization, the best efficiency of an improved OSC is found to be 17.36%, and the outcomes of the simulated OSC are referenced to the results of the experimentally implemented OSC. These results provide a possible future direction for developing GO-based OSCs with higher efficiency.

“…32,33 S. Ozcan et al reported using GO-doped PEDOT:PSS as an HTL in inverted bulk heterojunction of P3HT:PC 61 BM solar cell, which improved the device efficiency from 2.69 to 2.75%. 34 On the other hand, S. Rafique et al reported using a GO/PEDOT:PSS double-decked layer as HTL for PCDTBT:PC 71 BM solar cells, which led to a PCE of 4.28%; in comparison, GO or PEDOT:PSS HTLs on their own achieved PCEs of 2.77 and 3.57%, respectively. 23 The addition of GO to PEDOT:PSS for use as an HTL in a device architecture to be ITO/PEDOT:PSS:GO/PTB 7 :PC 71 BM/Al scored a PCE of 5.22%.…”
