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.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
