We suggested improving the conversion efficiency of Dye-sensitized solar cells (DSSCs) by the micro-nano periodic textures to control the diffusion angle of the incident light for certain absorbed wavelengths of the used dye. A periodic texture (Prd-Tx) was designed to enhance the light path of the wavelength of DSSCs’ dye absorption with a wide process window by the optical simulation (Pitch: 1400 nm, Pillar diameter: 460 – 560 nm, Pillar height: more than 500 nm). The Prd-Tx was fabricated by the photolithography processes and nanoimprinting (Pitch: 1400 nm, Pillar diameter: 500 nm, Pillar height: 1000 nm). The Prd-Tx increased the DSSCs’ conversion efficiency (η of 3.13%), surpassing our previous best result (refabricated W-Tx, η of 3.08%). It was considered that the ohmic loss was suppressed owing to the Prd-Tx enhanced electrical conductivity at the interface between the transparent electrode, F-doped Tin oxide (FTO) and TiO2.

“…shown good photovoltaic performance, but overall, the performance of Pt-free DSSCs needs to be improved. Recently, transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), tungsten disulfide (WS2), and molybdenum diselenide (MoSe2) have attracted research interest due to their excellent optical and electrical properties [34,48,49]. MoS2 has been widely used as an electrocatalyst for the fabrication of electrochemical sensors due to its excellent catalytic properties [50].…”

In this work we reported the hydrothermal preparation of molybdenum disulfide (MoS2). The phase purity and crystalline nature of the synthesized MoS2 were examined via the powder X-ray diffraction method. The surface morphological structure of the MoS2 was examined using scanning electron microscopy and transmission electron microscopy. The specific surface area of the MoS2 was calculated using the Brunauer-Emmett-Teller method. The elemental composition and distribution of the Mo and S elements were determined using energy-dispersive X-ray spectroscopy. The oxidation states of the Mo and S elements were studied through employing X-ray photoelectron spectroscopy. In further studies, we modified the active surface area (3 mm) of the glassy carbon (GC) electrode using MoS2 as an electrocatalyst. The MoS2 modified GC electrode (MSGC) was used as an electrochemical sensor for the detection of thiabendazole (TBZ). Linear sweep voltammetry (LSV) was used as the electrochemical sensing technique. The MSGC exhibited good performance in the detection of TBZ. A limit of detection of 0.1 µM with a sensitivity of 7.47 µA/µM.cm2 was obtained for the detection of TBZ using the LSV method. The MSGC also showed good selectivity for the detection of TBZ in the presence of various interfering compounds. The obtained results showed that MoS2 has good electrocatalytic properties. This motivated us to explore the catalytic properties of MoS2 in dye sensitized solar cells (DSSCs). Thus, we have fabricated DSSCs using MoS2 as a platinum-free counter electrode material. The MoS2 counter electrode-based DSSCs showed good power conversion efficiency of more than 5%. We believe that the present work is beneficial for the scientific community, and especially for research surrounding the design and fabrication of catalysts for electrochemical sensing and DSSC applications.
