A variable series resistance mechanism to explain the negative capacitance observed in impedance spectroscopy measurements of nanostructured solar cells
RSC Publishing (2011-01-24)A simple model for conductivity modulation in a recombination diode is discussed to explain the observation of negative capacitance at forward bias observed in many optoelectronic devices. We formulate the basic ... -
Characterization of nanostructured hybrid and organic solar cells by impedance spectroscopy
RSC Publishing (2011-04-06)We review the application of impedance spectroscopy in dye-sensitized solar cells, quantum dot-sensitized solar cells and organic bulk heterojunction solar cells. We emphasize the interpretation of the impedance parameters ... -
Diffusion-Recombination Determines Collected Current and Voltage in Polymer:Fullerene Solar Cells
American Chemical Society (2012)The basic operating mechanisms of organic bulk-heterojunction cells comprising poly(3-hexylthiophene (P3HT): [6,6]-phenyl-C 61-butyric acid methyl ester (PCBM) blends are examined based on the selection of diverse materials ... -
Enhanced Carrier Transport Distance in Colloidal PbS Quantum-Dot-Based Solar Cells Using ZnO Nanowires
American Chemical Society (2015-11)Nanostructured solar cells are a promising area of research for the production of low cost devices that may eventually be capable of complementing or even replacing present technologies in the field of solar power ... -
Influence of the Potassium Chloride Concentration on the Physical Properties of Electrodeposited ZnO Nanowire Arrays
American Chemical Society (2008)The structural, electrical, and optical properties of zinc oxide nanowire arrays electrodeposited from the reduction of molecular oxygen in aqueous solutions containing zinc chloride and potassium chloride are studied as ...
