For the development of transparent solar cells with transition metal dichalcogenide (TMD) which is a novel semiconductor material, we tried to fabricate a transparent and large area TMD solar cell with WS₂ thin film directly synthesized on the entire surface of a transparent quartz substrate. Indium tin oxide (ITO) was used as a transparent electrode. As a result, clear power generation of TMD / ITO transparent solar cell can be observed. Furthermore, it was found that power generation efficiency improves by optimizing synthesis condition of WS₂ thin film. This achievement is very important for realizing the industrial application of TMD as a transparent solar cell.
