Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of around 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane ...
Transforming light into electricity is no mean feat. Some devices, like solar cells, use a closed circuit to generate an electric current from incoming light. But another class of materials, called photocathodes, generate ...
Physicist Richard Feynman highlighted the importance of fluctuations in living matter when he stated, "Everything that living things do can be understood in terms of the jigglings and wigglings of atoms." This holds true ...
Improving the sensitivity of light sensors or the efficiency of solar cells requires fine-tuning of light capturing. KAUST researchers have used complex geometry to develop tiny shell-shaped coverings that can increase the ...
Scientists at Tokyo Institute of Technology have theoretically demonstrated that special tetrahedron nanostructures composed of certain metals have a higher degree of symmetry than the geometrical symmetry of spherical atoms. ...
