Impedance spectroscopic analysis of high-performance dye sensitized solar cells based on nano-clay electrolytes
Elsevier (2016)In this work we present quasi-solid state dye-sensitized solar cells obtained employing artificial hydrotalcite nano-clay as electrolyte additive, with a greatly improved photo-energy conversion efficiency of up to 10.9% ... -
Photocurrent enhancement in dye-sensitized photovoltaic devices with titania–graphene composite electrodes
Elsevier (2012)Photovoltaic performance of dye-sensitized solar cell (DSC) devices based on a new titania–graphene paste has been investigated using Impedance Spectroscopy (IS) technique. The results provide key information about device ... -
Trap origin of field-dependent mobility of the carrier transport in organic layers
Elsevier (2011)In the measurements of space-charge limited current (SCLC) transport in disordered organic semiconductors, it is often observed that carriermobility depends on bias voltage. Two continuous models have been applied for the ... -
Trap-limited mobility in space-charge limited current in organic layers
Elsevier (2009)Space-charge limited current transport in organic devices, relevant to the operation of a range of organic optoelectronic devices, is analyzed in the frequency domain. The classical multiple trapping picture with one ...
