Through research for a material that is low cost, earth abundant, and highly efficient, Tungsten Sulfide (WS2) has been identified as a promising solution. From literature, it has been shown that WS2 possesses a band gap of 1.9 eV, which is ideal for a top layer heterostructure cell. While this is a favorable value, other properties needed to understand its value as a photovoltaic material are unknown. Through research, WS2 films will be grown through a sputtering deposition process and electrical characterization measurements will be performed to study these missing properties.
