Enhancement in open circuit voltage of organic photovoltaic devices

1. Introduction. Small-molecule organic photovoltaic (OPV) devices have been studied extensively and rapidly developed to take advantage of their low cost and flexibility compared with inorganic devices [1], [2], [3].Since Tang reported the two-layer copper-phthalocyanine (CuPc)-based OPV device with power conversion efficiency (PCE) of ∼1% in

Local VOC Measurements by Kelvin Probe Force

This work focuses on the extraction of the open circuit voltage (VOC) on photovoltaic nanowires by surface photovoltage (SPV) based on Kelvin probe force microscopy (KPFM) measurements. In a first approach, P-I-N

Advanced Energy Materials: Vol 5, No 23

The open-circuit voltage evolution and charge transfer state interfaces in ternary organic photovoltaic blends are investigated using several model systems. The changes in subgap spectra from energetic disorder and increased population of higher energy states are analyzed and the lowest charge transfer state distribution is observed to shift due to local

Moreover, the loss of local open-circuit voltage (V OC) in the bending mode was investigated by the carrier excitation mechanism. Furthermore, the degradation of photovoltaic parameters due to the

Molecular and Morphological Influences on the Open Circuit

We explore the dependence of the dark current of C60-based organic photovoltaic (OPV) cells on molecular composition and the degree of intermolecular interaction of several molecular donor materials. The saturation dark current density, JS, is an important factor in determining the open circuit voltage, Voc. The Voc values of OPVs show a strong inverse correlation with JS. Donor

Our lab, in collaboration with others, has developed a new nanoimaging technique to map the open-circuit voltage in optoelectronic devices. This method can advance the current state-of-knowledge of the fundamental processes governing solar cell performance in order to enhance overall photovoltaic efficiencies.

The origin of the open-circuit voltage in polyfluorene-based

The influence of device structure on the open-circuit voltage of polyfluorene-based photovoltaic devices has been investigated. Bilayers of hole- and electron-accepting polyfluorenes have been fabricated using an aqueous "float-off" lamination technique and subsequently incorporated into organic photovoltaic devices with a range of cathodes and anodes. A scaling of the open
