The thrust of innovative ideas mated with precision and passion for the benefit of nature. Being pioneers in the construction of sustainable solar energy systems, we make a meaningful and valuable contribution to establishing photovoltaics as a cost-efficient renewable energy provider. We are passionately committed to innovative impulses and comprehensive sustainable solutions for erecting solar energy facilities, leaving our mark on all processes and procedures of a project through precision, stability und safety.
The nanostructure for capturing light is imprinted on silicon oxide blue and then "levelled" with titanium oxide green. The result is an optically rough but smooth layer on which crystalline silicon can be grown.
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, bekanntschaften kostenlos ohne registrierung could do even better if their shiny singletrails feldberg taunus reflected less light. A team led by Prof.
Such surface structures can even ultimately reduce the efficiency by impairing the electronic properties of the material. The idea that David Eisenhauer worked out as part of his doctorate in Becker's team sounds quite simple, but it requires a completely new approach: The procedure consists of several steps: This creates tiny, regularly arranged cylindrical elevations that are ideal for capturing light.
However, the absorbing layer of crystalline silicon cannot grow flawlessly on this rough surface, so these structures have an unfavorable effect on the quality of the solar singletreff calw. In order to resolve this conflict, a very thin layer of titanium oxide is spin coated on top of the nanostructure in order to produce a relatively smooth surface on which the actual absorber material can be deposited and crystallized.
It reduces reflections and brings more light into the absorbing layer without impairing its electronic properties. The procedure is now patented. As part of the BerOSE Joint Bekanntschaften kostenlos ohne registrierung, she works closely with single frauen detmold Zuse Institute to use computer simulations for understanding the effects of nanostructuring bekanntschaften kostenlos ohne registrierung material properties.
