Superb Material for Solar Cells:
Microcrystalline Silicon Carbide

Photovoltaic is an inexhaustible, clean source of energy. However, production costs for solar cells are still relatively high. The shiny power generators could become more economical if they could be constructed from the thinnest layers possible. Thin-film solar cells based on a silicon material, in which the atomic components are not arranged in crystal lattices, are already being produced.

Solar cells: this is how it works

If an electrical conductor is connected to the contacts of a solar cell, electrons flow from the negative pole to the positive pole: an electric current is produced, just like in a battery. In order to make this possible, electrons and mobile positive charge carriers – atoms that have emitted an electron – must initially be produced in the solar cell and then separated from each other in such a way that they accumulate at the contacts. The energy required for these processes comes from the particles of light captured by the solar cell.
