Electro-optical characterization of ruthenium-based dye sensitized solar cells: A study of light soaking, ageing and temperature effects
2017
Abstract In this work, we report on the electro-optical characterization of Dye Sensitized Solar Cells (DSSCs) which use ruthenium complexes as sensitizers. In particular, several kinds of measurements have been performed to study the electrical performances and the efficiency levels of the cells at different operating conditions. In detail, the measurements have been conducted at varying temperatures and hours of light soaking. Our results show that the short circuit current density J SC , the open circuit voltage V OC and the conversion efficiency η increase with the hours of light soaking, while they decrease with temperature. A thorough investigation on the light soaking process at the …

This time it’s different? Effects of the Eurovision Debate on young citizens’ and its consequence for EU democracy – evidence from a quasi-experiment…
2017
For the very first time in EU history, the 2014 EP elections provided citizens with the opportunity to influence the nomination of the Commission President by casting a vote for the main Europarties’ ‘lead candidates’. By subjecting the position of the Commission President to an open political contest, many experts have formulated the expectation that heightened political competition would strengthen the weak electoral connection between EU citizens and EU legislators, which some consider a root cause for the EU’s lack of public support. In particular, this contest was on display in the so-called ‘Eurovision Debate’, a televised debate between the main contenders for the Commission Presiden…
Results from the Fourth WMO Filter Radiometer Comparison for aerosol optical depth measurements
2018
Abstract. This study presents the results of the Fourth Filter Radiometer Comparison that was held in Davos, Switzerland, between 28 September and 16 October 2015. Thirty filter radiometers and spectroradiometers from 12 countries participated including reference instruments from global aerosol networks. The absolute differences of all instruments compared to the reference have been based on the World Meteorological Organization (WMO) criterion defined as follows: 95% of the measured data has to be within 0.005 ± 0.001∕m (where m is the air mass). At least 24 out of 29 instruments achieved this goal at both 500 and 865 nm, while 12 out of 17 and 13 out of 21 achieved this at 368 and 412 nm,…
Merging science and arts to communicate nature conservation
2015
Abstract As a response to overall negative attitudes on nature conservation, Latvian scientists and artists launched a new initiative to communicate biodiversity. Unlike previous efforts, this initiative also included arts (poetry, music, dance and photo/video) as part of the information campaign. This project, named Nature Concert Hall, has been very successful between 2006 and 2012 in terms of receiving national and international recognition; this paper aimed to evaluate its efficiency in increasing the public’s knowledge and awareness of nature conservation issues and pro-environmental behaviour. We used an electronic web-form survey to investigate the views of the Nature Concert Hall’s …
Data from: Genetic and ecotypic differentiation in a Californian plant polyploid complex (Grindelia, Asteraceae)
2015
Studies of ecotypic differentiation in the California Floristic Province have contributed greatly to plant evolutionary biology since the pioneering work of Clausen, Keck, and Hiesey. The extent of gene flow and genetic differentiation across interfertile ecotypes that span major habitats in the California Floristic Province is understudied, however, and is important for understanding the prospects for local adaptation to evolve or persist in the face of potential gene flow across populations in different ecological settings. We used microsatellite data to examine local differentiation in one of these lineages, the Pacific Coast polyploid complex of the plant genus Grindelia (Asteraceae). W…
