“…The plots for the CB and Tetralin:ODT cells were composed of two arcs at higher (>50 kHz) and lower frequency (<50 kHz), which are denoted as arcs 1 and 2, respectively. Arcs 1 and 2 were derived from the n-type TiO x semiconductor and photoactive P3HT:PCBM layer, respectively 20,21,23,30) . Rs represents the series resistance consisting of ohmic components, while R1 and R2 are resistance components forming a parallel circuit with constant phase elements denoted CPE1 and CPE2, respectively, as shown in the inset of Figure 6a.…”

The initial performance and subsequent degradation of inverted polymer solar cells (ITO/TiO x /PCBM:P3HT/PEDOT:PSS/Au, TiO x cell) is studied using photocurrent-voltage measurements combined with ac impedance spectroscopy (IS) and carrier mobility measurements. The TiO x 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 TiO x 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.IS measurements suggested that the degradation of the Tetralin:ODT cell was caused by a morphology change of the P3HT:PCBM layer that made efficient photoinduced charge separation difficult.

An inverted bifacial polymer solar cell was developed using a conductivity-controlled transparent PEDOT:PSS as a hole collection layer and a striped Au electrode with a large open aperture ratio (Rap) as a hole collection electrode. We investigated the performance of the device by varying the inter-electrode distance of the striped Au electrode and the sheet resistance of the PEDOT:PSS film.The device using Clevios P (PEDOT:PSS) showed a maximum electric output (P w ) in the R ap range of 50 to 65 %. When alcohol-treated Clevios P (Clevios P+) with a lower electrical resistance was used, the maximum P w increased by 40 % compared with that of the device using Clevios P. The maximum P w was obtained in the R ap range of 84 % as the hole collection efficiency of the striped Au electrode improved with the decreased sheet resistance of the PEDOT:PSS.

“…[9][10][11][12] Moreover, one of the most important advantages of an OPV is that the organic/inorganic photoactive and carrier transport layers and metal/inorganic electrodes solution can be processed, which drastically lowers the fabrication cost because it is not necessary to use a vacuum system, and a roll-to-roll printing process is possible. In fact, several types of solution processes for fabricating OPVs have already been demonstrated, including spray coating, 13 gravure printing, 14 flexographic printing, 15 screen printing, 16 and electrospray deposition.…”

The electrical and physical properties at the interface between the ZnO electron transport/collection layer and an organic photoactive layer play important roles in determining photovoltaic performance. Therefore, we have fabricated ZnO nanorods and optimized the coating conditions used for deposition of the ZnO seed layer, which serves as a nucleation site for crystal growth. First, the relationship between the concentration of the ZnO precursor solution (zinc acetate dihydrate and hexamethylenetetramine in methanol) and diameter of the ZnO nanorods was examined, and we showed that the diameter continuously decreased with increasing concentration, reaching a minimum of 23 nm. Further, we investigated density of ZnO nanorods and photovoltaic performance of the inverted cell as a function of the rotation speed used during the spin coating process to deposit the ZnO seed layer. A low density of ZnO nanorods was obtained when the rotation speed was low, and this caused the short circuit current density, open circuit voltage, and fill factor of the organic photovoltaics to decrease. As a result, a maximum photoconversion efficiency of 3.0% was achieved, and this value was 1.6-fold greater than that measured using a reference device containing no ZnO nanorods (photoconversion efficiency: 1.9%).
