“…Thus, similar to the conventional OSC, as the peak of J SC was wider, an optimal active layer thickness in the range 90 nm to 115 nm was used. It was also distinctively conclusive that the inverted OSC gave a higher J SC than the conventional OSC, which also agreed with the experimental result [52].…”

Using the optical transfer matrix method, we optimized the layered structure of a conventional and an inverted BHJ OSC with the active layer made of blended PTB7-Th:PNDI-T10 by maximizing the optical absorption and, hence, the JSC. The maximum JSC thus obtained from the optimised structure of the inverted OSC was 139 Am−2 and that of the conventional OSC was 135 Am−2. Simulation of the electric field distribution in both inverted and conventional OSCs showed that the formation of a single CIP was obtained in the active layer of thickness 105 nm in both OSCs. As the light incidents from the ITO side, it was found that excitons were generated more closely to ITO electrode, which favors the efficient charge transport and collection at the opposite electrodes in the inverted OSC, which produces higher JSC.

“…P3HT, the most well-studied polymer in OPVs, is known to be p-type doped with a background carrier density of 5 × 10 15 to 5 × 10 16 cm -3 [5,7,39]. While the optimal thickness for P3HT:PC 61 BM OPVs is ~ 200 nm [33], devices with thickness varying between 100 [38] and 800 nm [40] have been studied.…”

“…To expand the active layer’s absorption range, tandem OSCs have been proposed to stack two single-junctions with different absorption ranges [ 49 , 50 ]. According to the charge flow direction, OSCs can be divided into conventional and inverted devices (see Figure 1 ) [ 51 ]. Under light irradiation, photons are absorbed by the donor material in the active layer to form excited states, called excitons, which are bound electron-hole pairs.…”

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.
