Improved high temperature stability of organic solar cells using a phosphine oxide type cathode modification layer

[摘要]：The high temperature stability of the organic solar cells (OSCs) was improved using a phosphine oxide based organic cathode modification layer instead of LiF. The OSC modified with the phosphine oxide cathode modification layer showed constant device performances after a thermal treatment at 90 degrees C, while the LiF based OSC exhibited degraded device performance after the thermal treatment. The use of the phosphine oxide based interlayer was effective to improve the high temperature stability of the OSC. (C) 2010 Elsevier B.V. All rights reserved.
