Photoconductivity is the incremental change in the electrical conductivity of a semiconductor
or insulator upon illumination. The behavior of photoconductivity with photon energy, light …

Organic semiconductors are promising candidates for future applications in solar energy
conversion. Recent investigations of bulk heterojunction (BHJ) semiconductors have …

In this chapter, we present characterization techniques based on the uniform illumination of
photoconductive semiconductors with monochromatic light. Among these techniques, one is …

In this chapter, we detail photoconductivity techniques based on the illumination of a sample
in a coplanar electrode configuration with a light intensity periodically modulated in space …

To investigate the electron transport properties of hydrogenated amorphous silicon (a-Si: H),
a series of quantum simulations and electron transport analyses were performed. The target …

In this work, we present two new pairs of formulas to obtain a spectroscopy of the density of
states (DOS) in each band tail of hydrogenated amorphous silicon (a-Si: H) from …

Thin film semiconductors are more and more the major components of solar devices.
Nevertheless, these materials are still the subjects of intense research to improve their …

Following up on some recent work that has been presented (Orapunt et al., J Appl Phys 119:
065702-1-12, 2016), we report on the optical properties associated with a unique form of …

The Moving photocarrier Grating Technique (MGT) allows the simultaneous determination of
the photocarrier drift mobilities and the small-signal recombination lifetime of …

We solve the general equations for a semiconductor of photoconductivity dominated by one
type of carrier and obtain two pairs of analytical formulas for a density of state (DOS) …
