The basis of energy transformation is that, when light is absorbed, it generates motion-filled charged particles, which in the device force the electrochemical potentials and the built-in electric space due to the difference of the electron exit works. Currently, the world top is over 48%! How nice it would be if the solar cell of everyday life would work with this efficiency. There are one or two lab results in this category, followed by the twenty percent category. The element of everyday life is made up of cells with 16-18% efficiency, but arranged in a module because of the glass and wiring, the efficiency of the module is only around 12-16%. In addition, the slightly better price is significantly higher than a few tenths of a percent less power. So, for those who are not scarce, they can create significantly less.
