Abstract:
Provided are a solar cell that can be manufactured by non-vacuum process and can have more excellent photoelectric conversion efficiency and a manufacturing method therefor as well as such a semiconductor device and a manufacturing method therefor. A solar cell, includes at least a first semiconductor layer (140) and a second semiconductor layer (130). The first semiconductor layer (140) includes metal oxide particles of 1 nm or more and 500 nm or less in average particle size and a compound having relative permittivity of 2 or more and 1,000 or less. For instance, the content of the organic compound in the first semiconductor layer (140) is 10 mass % or more and 90 mass % or less.
