 note = {The initial performance and subsequent degradation of inverted polymer solar cells [indium-tin oxide/titanium oxide (TiOx)/[6,6]-phenyl C61 butyric acid methyl ester (PCBM): regioregular poly(3-hexylthiophene) (P3HT)/poly(3,4-ethylenedioxylenethiophene):poly(4- styrene sulfonic acid)/Au, TiOx cell] are studied by photocurrent-voltage measurements as well as ac impedance spectroscopy (IS) and carrier mobility measurements. The TiOx cells containing a P3HT:PCBM layer prepared from a solution of chlorobenzene (CB) showed a maximum power conversion efficiency (PCE) of 2.23%. In contrast, the TiOx cells containing a P3HT:PCBM layer prepared from a solution of 1,2,3,4- tetrahydronaphthalene (tetralin) containing 2 vol- 1,8-octanedithiol (ODT) exhibited a maximum PCE of 2.92%. However, after exposure to light irradiation for 100 h, the maximum PCE of the tetralin:ODT cell decreased to 68% of its initial value. On the other hand, over 96% of the maximum PCE was maintained in the CB cell after 100 h of irradiation. The IS measurement results suggest that the degradation of the Tetralin: ODT cell was caused by a morphological change of the P3HT:PCBM layer that made efficient photoinduced charge separation difficult. © 2014 The Japan Society of Applied Physics.},
