Charge carrier mobility and lifetime of organic bulk heterojunctions analyzed by impedance spectroscopy
Elsevier (2008)Charge carrier diffusion and recombination in an absorber blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C<sub>61</sub>-butyric acid methyl ester (PCBM) with indium tin oxide (ITO) and aluminium contacts have been ... -
Consistent formulation of the crossover from density to velocity dependent recombination in organic solar cells
AIP Publishing (2015)Carrier recombination is a central process in bulk heterojunction organic solar cells. Based on the competition of hopping rates that either implies escape in a broad density of states or recombination across the interface, ... -
Kinetics of occupancy of defect states in poly(3-hexylthiophene): fullerene solar cells
Elsevier (2012-01)Energetics and kinetics of defects in the effective band gap of organic bulk heterojunctions are determined by means of capacitance methods. The technique consists of calculating the junction capacitance derivative with ... -
Light-modulated TiOx Interlayer Dipole and Contact Activation in Organic Solar Cell Cathodes
Wiley (2014-10-22)Understanding working mechanisms of selective interfacial layers and the underlying energetics of the organic semiconductor/electrode interface is an issue of primary concern for improving organic solar cell technologies. ... -
Temperature dependence of open-circuit voltage and recombination processes in polymer–fullerene based solar cells
Elsevier (2011)In this article, we have studied the temperature and illumination dependence of open-circuitvoltage (VOC) in polymer–fullerenebasedsolarcells. It has been observed that VOC at higher illumination intensities gets converged ... -
Temperature dependence of open-circuit voltage in organic solar cells from generation-recombination kinetic balance
Elsevier (2010)The variation in the open-circuit voltage of bulk-heterojunction organic solar cells with temperature and light intensity is analyzed based on the kinetic balance between photogeneration and recombination rates, by determining ...
