Organic solar cells are actively pursued by the scientific and industrial communities. Several advantages conveyed by organic solar cells are that they are lightweight and flexible and allow for scalable material production and cost effective roll-to-roll coating and printing techniques. Efficiency of ＞10% was disclosed in small area solar cells with various device architectures, which indicated the rapid progress over the last several years and the great potential of organic solar cells as an alternative source of energy. In order for organic solar cells to fully mature from research and development into cost effective products, one of the important issues is to achieve long-term stability of organic solar cells. A fundamental comprehension of the mechanism of device degradation occurring in organic solar cells and the understanding of design principles for achieving high solar cell stability are necessary to push this area forward. |
