Summary: | An object of the present invention is to enhance the photoelectric conversion performance to more than the limit possessed by prior organic solar cells in arts of organic solar cells in which an organic semiconductor layer is constituted by at least two material layers. As a means of achieving this object, the organic solar cell according to the present invention is an organic solar cell comprising a pair of electrode layers 10, 30 and therebetween an organic semiconductor layer 20 including at least two material layers, wherein the organic semiconductor layer 20 includes: a first material layer 24 having thickness-wise through spaces; a second material layer 22 (formed from such as a soluble material) being disposed adjacently to the first material layer 24; and a mingled range 26 which is disposed in a part, adjacent to the second material layer 22, of the first material layer 24 and formed by such as a process including the steps of making a liquid film of a soluble material (this material is to form the second material layer 22) penetrate and then hardening it and in which a part of the material of the second material layer 22 is mingled with the first material layer 24 in the form of having entered the through spaces of the first material layer 24. |
