| Popis: | A relatively long lifetime organic solar cell, containing a thin tris-8-hydroxy-quinolato aluminum (Alq 3 ) layer under an Au cathode, is described. Half-lifetime of the cell in the darkness is over 7 weeks and 30% of the initial power conversion efficiency ( η ) is obtained after 18 weeks. This represents a substantial increase in lifetime compared to that of the unencapsulated Al-cathode cells. Efficiency is enhanced by 60 times compared to a cell that does not contain Alq 3 , being 0.60%. The proposed role of Alq 3 /Au cathode in this cell is discussed in detail. |
