Monolithic two-terminal (2T) perovskite/CuInSe2 (CIS) tandem solar cells (TSCs) combine the promise of an efficient tandem photovoltaic (PV) technology with the simplicity of an all-thin-film device architecture that is compatible with flexible and lightweight PV. In this work, we present the first-ever 2T perovskite/CIS TSC with a power...

The selenisation of Cu-Ga-In metallic precursors is investigated by in-situ X-Ray Diffraction (XRD) in a selenisation tool which mimics at the laboratory scale an industrial tool (thus fully scalable) and allows fine control over the selenisation parameters and reproducibility. In this setup, the interdiffusion of Ga and In was significantly...

Partial shading of Cu(In,Ga)(Se,S)2 (CIGS) photovoltaic (PV) modules is getting more attention, as is witnessed by the increase in publications on this topic in recent years. This review will give an overview of shading tests executed on CIGS modules and focuses on the more fundamental aspects that are often studied on cells. Generally, CIGS...

This study explores the leaching of oxyanionic metalloid species (As, Mo, Se, V and Cr) from alkali activated slag-fly ash materials (AAM), dependent on various mixture parameters i.e., activator molarity, slag-fly ash precursor/binder compositions, liquid to binder ratio, curing time and strength. The analyses focusses on the leaching of...

Degradation rates and mechanisms for molybdenum back contacts and ZnO:Al front contacts exposed to damp heat were obtained from literature and experiments. It was found that molybdenum back contacts with a higher density and covered by a MoSe2 film are more stable than their low density, bare counterparts. For ZnO:Al front contacts various...

Two step atmospheric pressure processing of Cu(In,Ga)(Se,S)2 absorbers is an industrially attractive technology to produce CIGS thin film modules. For this procedure, absorber sulfurization is required to increase the Voc and thus the efficiency of the solar cells. Raman spectroscopy was used to qualitatively identify the presence of sulfur on...

In this manuscript we present the first successful application of a spatial atomic-layer-deposition process to thin film solar cells. Zn(O,S) has been grown by spatial atomic layer deposition (S-ALD) at atmospheric pressure and applied as buffer layer in rigid and flexible CIGS cells by a lab-scale (15x15 cm2) S-ALD set-up. We achieved values of...

Modification of the absorber surface properties by Cd2+ treatment (Cd2+ partial electrolyte) results in the following: formation of Cd(OH)2 on the absorber surface, deposition of thinner chemical bath-deposited CdS buffer layer, and a smaller space charge region. The impact on electrical performances is as follows: decrease of the series...

Current reference values for selenium, an essential micronutrient, are based on the intake of selenium that is required to achieve maximal glutathione peroxidase activity in plasma or erythrocytes. In order to assess the evidence of relevance to setting dietary reference values for selenium, the EURRECA Network of Excellence focused on...

BACKGROUND: Selenium may prevent advanced prostate cancer (PCa), but most studies on this topic were conducted in populations with moderate to high selenium status. We investigated the association of toenail selenium, reflecting long-term selenium exposure, and advanced PCa risk in a population from the Netherlands where low selenium status is...

In this paper, we investigated different organic and inorganic hole-blocking contacts for amorphous selenium (a-Se)-based photodetectors: CeO2, TiO2, perylene tetracarboxylic bisbenzimidazole (PTCBI), and polyimide (PI). CeO2 has previously been used as a blocking layer for high-gain a-Se devices. TiO2 has similar properties to CeO2. PTCBI has a...

Objective: To investigate the association between selenium and the risk of Barrett's esophagus (BE), the precursor lesion of esophageal adenocarcinoma. Methods: Data from the prospective Netherlands Cohort Study were used. This cohort study was initiated in 1986, when 120,852 subjects aged 55-69 years completed a questionnaire on dietary habits...

Nulling interferometry is an important technique under development for the DARWIN planet finding mission which enables the detection of the weak infrared emission lines of an orbiting planet. This technique requires the use of single mode optical fibers transmitting light as far as possible in the infrared. Tellurium based glasses transmit...

Background & Aims: Selenium may protect against the development of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric cardia adenocarcinoma (GCA). Only in very few studies have the associations with ESCC and GCA been investigated, and no epidemiologic studies exist on EAC. Methods: We studied the association...

Te80-xGe20Sex glasses have been prepared along the GeSe4-GeTe4 axis using the classical method in silica tube under vacuum. A phase separation domain appears for composition around Te40Ge20Se40. Our attention was turned toward the Te-rich compositions corresponding to 1 < x < 5 at.%. These glasses are transparent from 4 to about 20 μm without...

Micronutrients are involved in specific biochemical pathways and have dedicated functions in the body, but they are also interconnected in complex metabolic networks, such as oxidative-reductive and inflammatory pathways and hormonal regulation, in which the overarching function is to optimise health. Post-genomic technologies, in particular...

Diet has been hypothesized to play a role in the etiology of gastrointestinal cancer for a long time. Initially, strong evidence of such effects was found in retrospective epidemiological studies. Dietary habits, in particular those from the distant past, are difficult to measure, however. Results from recent, prospective and larger studies of...

The ICG Technical Committee 13 (TC13 "Environment") have reviewed the methods for sampling and analysing selenium emissions from glass furnaces. Selenium is an important constituent of some types of glass but unfortunately, due to its high volatility, much of the selenium added to the batch of such glasses leaves the furnace in the waste gases....

We reviewed 37 prospective cohort and four intervention studies on potential dietary risk factors for prostate cancer, published between 1966 and September 2003. Some studies were limited by small size, crude measurement of dietary exposure and limited control for confounders. Intervention and prospective cohort studies support a protective role...
