摘要：
Polymer solar cell based on the blend of poly[2-methoxy-5-(2 '-ethyl hexoxy)-1,4-phenylene vinylene] (MEH-PPV) and [6,6]-phenyl C-61-butyric acid methyl ester (PCBM) with C-60 insertion layer were fabricated. The solar cell structure was ITO/poly(3,4-ethylenedioxythiopene) (PEDOT):poly(styrenesulfonate) (PSS)/MEH-PPV:PCBM/C-60/Al. It was found that the C-60 inserting layer Could increase the device performance and lifetime. The energy conversion efficiency (ECE) of the solar cell with C-60 layer reached about 1.89% under Air Mass 1.5, 100 mW cm(-2) illumination, which is enhanced in comparison with that of the device without C-60 layer. Mechanisms of the solar cell performance and lifetime dependence on the C-60 layer are discussed. (c) 2008 Elsevier B.V. All rights reserved.
