Language: The lecture will be given in English. Edgar had a wobbly crack at it and George, realising the attention this garnered, stood up three days later and took 17 steps. Actually, it wasnt quite as neat as that. The lecture will last for 40-45 minutes and afterwards the audience may ask questions. I have just realised I havent blogged since Christmas which corresponds exactly with the day the boys started walking. The lecture is an obligatory teaching test for those applying for admittance as docent and it should be possible for students and others with basic academic education in the relevant field to follow it. It will focus on the interaction of photons and electrons with thin films, using the example of Cu(In,Ga)Se2 solar absorbers. This lecture will provide a brief overview of the most common, state-of-the-art methods applied for thin-film material characterization. Thus, an in-depth understanding of the involved materials and interfaces is of highest importance for further innovation and device improvement. However, this down-scaling creates new challenges with respect to homogeneous, phase-pure film growth and interface engineering. 100 times thinner than conventional Si devices) to absorb most of the sunlight. This is the concept of so-called thin-film solar cells, which use only micrometre-thick layers (i.e. Possible ways to reduce the prize/kWh ratio are to i) increase the conversion efficiency and/or ii) decrease material consumption. Actio Et Ractio Artist: Omophagia Album: Guilt By Nescience, 2010 Has been played on. By continuing to use this website, you agree to our. ' This really doesn't much apply to how we react to things as humans on an emotional level.It was the first thing that came to mind when I thought about this idea. Find out at which radio station you can hear Omophagia - Actio et Reactio. Here we show that optical binding of an asymmetric material system can result in non-reciprocal interactions between. Nevertheless, even in this case, the space translational invariance still imposes the conservation of canonical momentum. Apart from simultaneous progress in energy storage technologies, decreasing prices of PV-produced energy is key to accelerate the employment of solar modules. In Latin: 'Actio et Reactio' 'we conclude that these two forces are themselves equal and opposite, i.e., that they compensate each other. The symmetry in action and reaction between interacting particulate matter breaks down when the interaction is mediated by an out-of-equilibrium environment. Consequently, photovoltaics will become an integral part of the future energy mix all around the globe. In order to slow down and eventually stop climate change, a rapid rise in renewable energy production is mandatory.
