Reducing indium consumption, which is related to the transparent conductive oxide (TCO) use, a key challenge for scaling up silicon heterojunction (SHJ) solar cell technology terawatt level. In this work, we developed bifacial SHJ cells with reduced TCO thickness. We present three types of In2O3-based TCOs, tin-, fluorine-, and tungsten-doped In2O3 (ITO, IFO, IWO), whose thickness has been opti...

PURPOSE This study compares the effects of neutral temperature, cold and ice-slush beverages, with and without 0.5% menthol on cycling performance, core temperature (Tco) and stress responses in a tropical climate (hot and humid conditions). METHODS Twelve trained male cyclists/triathletes completed six 20-km exercise trials against the clock in 30.7°C±0.8°C and 78%±0.03% relative humidity. B...

This contribution is the second part of a presentation transparent conductive oxides, TCO. After general overview in first publication properties and applications TCO related to type oxide dopant, growth techniques temperature, we focus current one on three families used as electrodes photovoltaic, PV, cells modules. Indeed, new generations solar need optimizing with improved conductivity trans...

Abstract Economists advocate carbon pricing as the primary tool to reduce greenhouse gas emissions. However, very few governments have adopted a tax high enough meet international emission targets. Political challenges may stem from number of areas, including political mobilization by policy opponents, consumers’ willingness pay and regressivity many schemes, which might be addressed through re...

Interest in to the energy saving technology of by adopting low emissive glass for conventional building has been rapidly increasing [1]. Low emissivity (Low-e) glass has been widely used to increase the energy efficiency of windows. Low-e glass has advantages, such as a high transmittance of about 80% or more in the visible range and a low emissivity in the infrared (IR) range [2]. Recently, OM...

We employed ab initio global structural prediction algorithms to obtain the ground-state structure of CuBO2 This is a very promising p-type transparent conductive oxide that was synthesized recently, and thought to belong to the delafossite family. We proved that the true ground state is certainly not the delafossite structure, and that the most promising candidate is a low symmetry monoclinic ...

Am J Physiol Regul Integr Comp Physiol 290: R595–R600, 2006; doi:10.1152/ajpregu.00241.2005.—Purines, that is, adenosine and ATP, are not only products of metabolism but are also neurotransmitters. Indeed, purinergic neurotransmission is involved in...

Abstract We investigated the effect of B 2 H 6 plasma treatment on p-type hydrogenated amorphous silicon (p-a-Si:H) surfaces for high-performance heterojunction (SHJ) solar cells. Secondary ion mass spectroscopy measurements revealed that boron concentration at p-a-Si:H surface is increased by employing treatment. Furthermore, specific contact resistance decreased about one-third after No degra...

New and optimized metal-oxide thin films for both transparent-conductor and antireflection coatings have the potential to significantly improve photovoltaic devices. One approach to this task of discovery and improvement is to use a parallel optimization, i.e., a combinatorial, approach. Using internal seed funds, we have developed the initial deposition, characterization and analysis tools nec...
