Efficient organic photovoltaic tandem cells consist of P3HT:bis[60]PCBM and P3HT:[70]PCBM active layers and transparent conductive oxide interlayer are presented. A short circuit current and a conversion efficiency are estimated at more than 6 mA/cm2 and 5 % from optical simulation and optimization of the both active layer thicknesses. We clarify the almost same characteristics is achieved by the...
Photovoltaic properties of the cells consisting of a heterojunction of conducting polymer-fullerene systems and a semiconductor oxide thin film, which is transparent in the visible-wavelength range, have been investigated. Introducing the transparent semiconductor oxide, such as zinc oxide (ZnO), into the photovoltaic cells with conducting polymer - fullerene systems, high performance has been obtained...
Photovoltaic properties of a photovoltaic cell with a structure of indium-tin-oxide (ITO)/C 60 /conducting polymer (CP)/Au have been investigated. The C 60 /CP heterojunction in the photovoltaic cell was fabricated by spin-coating the solution of CP onto the C 60 thin film formed on ITO. Fabricated by this process, the photovoltaic cell has demonstrated the high efficiency...
