Andalusian scientists of the University of Cadiz and Pablo de Olavide University (Seville) are working on a project of improvement in the photoelectrochemical solar cells performance, an alternative to the silicon cells that are normally used. This would entail reductions in the cost of the parts.
The semi-conduit used in most photovoltaic solar cells that are commercialised is silicon, and despite its optimum efficiency in the exploitation of solar energy, it is a material whose production involves a high cost.
The alternative to using silicon sheets are Photoelectrochemical Solar Cells or DSSC (Dye Sensitised Solar Cells). These sheets are noted for using titanium dioxide as an electrical semi-conduit, rather economical and known for a long time as the basis of chemical photography. These sheets consist of two transparent pieces of glass that are electrical conduits between which there is a semi-conduit layer of titanium dioxide with an absorbed colouring and an electrolytic dissolution of iodine and potassium iodure.

Team develops fast, cheap method to make supercapacitor electrodes
18.07.2017 | University of Washington
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
