Abstract
Semiconductor-based photoanodes have sparked a lot more interest in the energy and environmental fields. A hydrothermal method was used to construct cobalt tungstate (CoWO4)/bio carbon (BC) nanocomposites. PXRD, SEM, UV-Vis DRS, and PL analyses are used to properly characterise the structural, morphological, and autoelectric properties of the synthesized samples. Because of the synergistic contact between CoWO4 and BC, this effective excition separation leads to increased photovoltaic activity. According to the XRD and TEM results, wolframite monoclinic structure with nanosized individual particles in the range of 30-40 nm was homogeneously adorned on the surface of BC nanosheets. By using dye-sensitized solar cells (DSSCs) as working electrodes, the photovoltaic properties of the cells were studied. The CoWO4/BC photoanode developed demonstrated high power conversion efficiency (7.01%), IPCE (73.21%), and long-term stability. In addition, the CoWO4/BC photoanode demonstrated high electrocatalytic activity, low resistance, and a high charge carrier process. The enhanced methodology was also thoroughly described.
