Many love photovoltaics, more and more 'public and private organizations are turning to solar, but that' still hampering further investment and 'the fact that today the photovoltaic system is not' competitive with petroleum in terms of cost and efficiency.
From Stanford, known universities 'U.S., but there's' interesting research results that would open interesting scenarios for the future.
Currently, for example, the ' efficiency of photovoltaic cells is around 20%, although there are certain types of cells that reach 40% but costs still too high for the market standard.
The new technology developed by researchers at Stanford will promise even an efficiency close to 60%.
What is this? First we talk about the combination of solar panels and panels thermodynamic by replacing silicon with gallium nitride, which is added on a layer of cesium in order to capture the energy in the form of heat that usually ends up being lost.
The initial problem of this kind of scenario and 'that these cells will only work at temperatures above 200 degrees, but these cells by coupling of parabolic solar concentrators, the problem would be solved, reaching close to 60% plus efficiency, at least according to forecasts researchers.
