Transition metal dichalcogenides (TMDCs) are promising materials as light absorbers of solar cells, but their applications are limited due to the difficulties in fabricating device-quality wafer-scale TMDC films. In this research, we demonstrate a solar cell performance of a large-area MoS₂ solar cell made by reactive sputtering. Au/MoS₂/Ag Schottky junction solar cell is made by reactive sputtering grown 14 nm thick MoS₂ film. We observed a solar cell performance from a cell size as large as 0.164 cm², larger than μm² scale TMDC solar cells reported so far made by exfoliation method. Even larger TMDC solar cells are feasible because the MoS₂ film could be deposited in cm² scale by reactive sputtering. There is still room for improvement in power conversion efficiency. We expect that improving the contact quality between Au and MoS₂ enhances the carrier collection efficiency.
