Provided are 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 as a result of an increase in the rate of movement of holes, and which can block oxygen and moisture penetrating from the outside and prevent deterioration of the photoactive capability of the polymer contained in the photoactive layer due to oxygen and moisture, thereby having an increased service life. |
