摘要: A solar cell capable of restricting carrier loss and yields higher energy conversion efficiency than was conventionally possible and a method of producing a solar cell enabling formation of a light absorbing layer containing quantum dots through a low-temperature process using a coating or printing method requiring no vacuum equipment or complicated apparatuses. The solar cell includes a light absorbing layer containing quantum dots in a matrix layer, and the light absorbing layer is connected to an N-type semiconductor layer on one side and to a P-type semiconductor layer on the other side. In the light absorbing layer, the quantum dots are made of nanocrystalline semiconductor and arranged 3-dimensionally uniformly enough and spaced regularly so that a plurality of wave functions lie on one another between adjacent quantum dots to form intermediate bands. The matrix layer is formed of amorphous IGZO.
