2015-1-30 · This week in the journal Science, Los Alamos National Laboratory researchers revealed a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. "These perovskite crystals offer promising routes for developing low-cost, solar-based, clean global energy solutions for the future," said Aditya Mohite, the Los

Cleavage of silicon by laser-based shock waves

it is possible to determine the corresponding length scale for real silicon crystals by using the critical fracture strength measured for the cleavage process. This is the so-called “engineering strength” of the material, which results from the production process and is always lower than the theoretical strength.

Buy Solar Panels | Learn from the Solar Experts

Making polycrystalline panels is cheaper and it''s a newer technology. The silicon cools unevenly and creates many different crystals giving it a less uniform appearance. Polycrystalline solar panels tend to be the most affordable, but they also put out a little less power.

Electric-field Control of Electronic States in WS2

Control of the carrier nuer is the key technique for realizing the quantum phase transition in solids 1.In the conventional field effect transistor (FET), it is achieved by use of the solid gate 1, 2.In such a device, electric potential gradient is uniform throughout the dielectric materials so that induced carrier nuer at the interface is limited, shown in Figure 1a.
