PV Nano Cell has commercially developed ‘Sicrys’, a single-crystal, nanometric silver conductive ink delivering enhanced performance for digital conductive printing in mass production applications. The inks are also available in copper-based form, delivering all of the product’s properties and advantages with improved cost efficiency.

Problem

Solar cell metallization is not yet fully optimized for cost and resource conservation. Cell producers currently endure silicon cell breakage during cell metallization, and higher-than-necessary costs for silver. Traditional screen printing of conductive grid lines involves direct contact with brittle cells, resulting in breakage and silicon waste. Additionally, the current technologies for metallization create lines that are wider and thicker than necessary, inflating silver costs.

Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.

The finding is reported in the July 29 issue of Science and was funded by the National Science Foundation and the U.S. Department of Energy. A provisional patent application has been filed.

Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting atmospheric carbon dioxide into fuel, solving two crucial problems at once. A solar farm of such “artificial leaves” could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.

The nextgen of Solar and fuel energy.

Scientists have just discovered a way to directly convert solar energy into a synthetic fuel using carbon dioxide. Current solar technologies operate in either photovoltaic solar or thermal solar. Photovoltaic solar energy is generated through solar panels, which are typically seen on the roofs of houses and many solar plants. The other method of thermal solar is typically only used in large-scale energy plants, as it used mirrors to focus solar energy to heat a liquid which then powers turbines. Both methods, however, involve the conversion of solar energy into electricity. While electricity is useful, much energy is lost in the storing of electricity, something that the conversion process to liquid fuel overcomes.
