초록

We investigated the MoS2 thin film layer by thermolytic deposition and applied it to the silicon solar cells. MoS2 thin films were made by two methods of dipping and spin coating of (NH4)2MoS4 precursor solution. We implemented two types of substrates of microtextured and nano-microtextured 6-in. Si pn junction wafers. The fabricated MoS2 thin film layer was analyzed, and solar cells were fabricated by applying the standard silicon solar cell process. The MoS2 thin film layer of sulfur-deficient form was deposited on the n-type emitter layer, and electrons, which are minority carriers, were well transported at the interface and exhibited photovoltaic solar cell characteristics. The cell efficiencies were achieved at 5% for microtextured wafers and 2.56% for nano-microtextured wafers.
