[13p-2M-5] Recent progress of thin film solar cells based on Cu2SnS3 and related materials
Keywords:Cu2SnS3,Solar cells,Thin films
Cu2SnS3 (CTS) is composed of elements that are inexpensive, non-toxic and abundant in the Earth's crust. It is a p-type semiconductor with a band gap energy of 0.9~1.0 eV and an absorption coefficient of the order of 104 cm-1. In the present study, CTS thin film solar cells were fabricated using a method involving co-evaporation and annealing in the presence of sulfur. In order to fabricate photovoltaic (PV) cells with the structure SLG/Mo/CTS/CdS/ZnO:Al/Al, CTS thin films were deposited on SLG/Mo substrates. A PV cell comprising a CTS thin film exhibited a PCE of 4.29%. Recent progress of thin film solar cells based on Cu2SnS3 and related materials will be discussed.
