Disclosed is a multilayer organic solar cell having a structure wherein an adhesive layer (3) is arranged between a first power generation layer (1) and a second power generation layer (2). This structure is obtained by forming the adhesive layer (3) on the first power generation layer (1) which is formed from an organic compound solution containing a donor material and an acceptor material, and then applying an organic compound solution containing a donor material and an acceptor material over the adhesive layer (3) for forming the second power generation layer (2). The adhesive layer (3) is composed of at least either of a transparent oxide and a transparent nitride. By having such a structure, the adhesive layer (3) prevents the solvent in the solution for the second power generation layer (2) from permeating into the first power generation layer (1) when the second power generation layer (2) is formed over the first power generation layer (1) by applying the solution. Consequently, the first power generation layer (1) is prevented from destruction or deterioration in functions.
