MANUFACTURING METHOD OF ORGANIC PHOTOVOLTAIC CELL FABRICATED BY SOLUTION PROCESS AND ORGANIC PHOTOVOLTAIC CELL FABRICATED THEREBY

摘要

PURPOSE: The manufacturing method of an organic solar cell is provided to improve energy conversion efficiency by effectively eliminating bubbles of the inner side of a thin film and to secure reproducibility. CONSTITUTION: The manufacturing method of an organic solar cell which includes a thin film formation step by a solution method is provided. A thin film is formed by drying by purging gas of a coating surface after coating solution. The moisture within the solution is dried by purging the gas of the coating surface. The gas more than the speed of wind 10m/sec is purged over 1 minute.
