Correlation between the power conversion efficiency and dimethyl sulfoxide (DMSO) modified poly (3,4-ethylene dioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) of polymer solar cells is studied. The PEDOT:PSS is modified by adding process additive (DMSO) during processing. However, highly conductive DMSO-PEDOT:PSS leads to tremendous errors in the measurement of the polymer solar cells. Our investigations...
A solution-processed vanadium oxide interlayer is introduced between the organic layer and the electrode for improving the performance of the polymer/ZnO nanorod hybrid solar cells. The results indicate that the vanadium oxide interlayer can serve as an electron-blocking layer to suppress the leakage current and an optical spacer to increase light absorption. As a result, the power conversion efficiency...
The selection of electrodes in ZnO nanorod-based polymer solar cells was investigated. Increases in the work function of metal electrode result in the increases in open-circuit voltage up to 120 mV, leading to improved performance.
