Abstract: A thin film solar cell includes a substrate, a first electrode and a second electrode positioned on one surface of the substrate, and a photoelectric conversion unit positioned between the first electrode and the second electrode. The photoelectric conversion unit includes a plurality of photoelectric conversion layers each including a p-type semiconductor layer, an i-type semiconductor layer, and an n-type semiconductor layer. At least one of the p-type semiconductor layers of the plurality of photoelectric conversion layers contains microcrystalline silicon (mc-Si) and amorphous silicon oxide (a-SiOx).
