Transition metal dichalcogenides (TMDCs) materials have a great potential for ultra-thin solar cells due to their high absorption coefficient. Molybdenum disulfide (MoS₂), one of the TMDC materials, is expected to have high net absorbance and high photocurrent generation.
In this work, MoS₂ films were deposited on quartz by reactive sputtering. We investigated the optical and electronic properties of MoS₂ films. With these measured parameters, we defined a homojunction structure in simulation software and obtained the 28.8% simulated power conversion efficiency of the solar cell made from MoS₂.
