Improvement of operation lifetime in organic solar cell coated with diphenylacetylene polymer film.
To improve the operation lifetime of organic solar cell, two different diphenylacetylene polymers were tested as UV blocking layer. One of them showed either stronger UV absorption or a relatively intense fluorescence emission in the visible region which is well overlapped with the absorption of P3HT in the OSC. The diphenylacetylene polymer film significantly improved the operation lifetime of the OSC by efficiently absorbing the UV light, while reducing the UV-light energy loss to a minimum by converting the UV light to visible light through a down-conversion process.
