ZnO/CdS/Cu(In,Ga)Se2 solar cells are investigated by spectrally resolved electroluminescence and electro-modulated photoluminescence. The results agree well with the reciprocity relation between luminescence emission and photovoltaic quantum efficiency. In contrast, the superposition of photoluminescence and electroluminescence emission is warranted only in a limited injection range. At higher injection levels, we observe a characteristic discrepancy between electroluminescence and electro-modulated photoluminescence which is reduced by light soaking. We attribute this anomaly to a potential barrier close to the CdS/Cu(In,Ga)Se2 interface. Hole injection into the space charge region during light soaking reduces this barrier and enhances the luminescence efficiency by a factor of 2.5.

This work presents a method for extracting the absolute local junction voltage of a‐Si:H thin‐film solar cells and modules from electroluminescence (EL) images. It is shown that the electroluminescent emission of a‐Si:H devices follows a diode law with a radiative ideality factor nr larger than one. We introduce an evaluation method that allows us to determine the absolute local junction voltage in cases of nr > 1, while existing approaches rely on the assumption of nr = 1. Furthermore, we find that the experimentally determined values of nr vary from sample to sample. It is also explained why the derived radiative ideality factor is influenced by the spectral sensitivity of the camera system used in the experiment. (© 2013 WILEY‐VCH Verlag GmbH & Co.

single sex only: i.e., five from the males and two from the females. To date, only one species, Indopadilla annamita (Simon, 1903) has been recorded from central Vietnam [Simon, 1903;Żabka, 1988; both sub Bavia].Recently, we performed several surveys of the spider fauna in the Chu Yang Sin National Park, Central Highlands, Vietnam and adjacent regions. As a result, a new jumping spider species -Indopadilla phantoani Hoang et Zhang, sp.n. -is described from the park based on both sexes. This is the second Indopadilla species found in Vietnam. Thus, with the addition of a new species from Vietnam, Indopadilla has become the largest genus of the tribe Baviini, with 15 species described to date. We have also provided a DNA barcode for the female of the new species for further studies. Materials and methodsSpecimens were hand-collected from foliage in the Chu Yang Sin National Park in Central Highlands of Vietnam. Legs II and III on the right side were cut out and preserved in absolute ethanol for DNA analyses, the remaining body was preserved in 70% ethanol for morphological examination. The specimens were examined with a Zeiss Stemi 508 stereo microscope (up to 100X magnification). Photos were taken using Jenoptik ProgRess CF Scan 12.5MP camera and Jenoptik ProgRes Capture Pro 2.10.0.1 software. The male palp and the female epigyne were examined and illustrated ABSTRACT. Indopadilla phantoani Hoang et Zhang, sp.n. (#$) is described from the Chu Yang Sin National Park, Central Highlands, Vietnam. A detailed description, illustrations of the copulatory organs and somatic features, and a distribution map are provided. A partial mtCOI-sequence for the female of the new species is also given.
