Abstract
An organic solar cell which includes an anode and a cathode that are arranged to face each other, a photoactive layer that is disposed between the anode and the cathode and contains a hole acceptor and an electron acceptor in mixture, and a metal oxide nano thin film layer that is disposed between the cathode and the photoactive layer and contains a metal oxide having an average particle size of 10 nm or less and having a particle size distribution such that 90% by number or more of the particles relative to the total number of the metal oxide particles has a particle size in the range of ±4 nm with respect to the average particle size, and a method for producing an organic solar cell. The organic solar cell has improved efficiency, and increased service life.
