Breaking Solar News: New light harvesting potentials uncovered
According to a new discovery named “Quantum-confined bandgap narrowing mechanism”, a method of absorbing natural light has been discovered. You may be wondering what this actually means. Well, according to this article over at Science Daily, using a wonder material called “Graphene”, it is possible to double or even triple solar absorption and energy conversion efficiency.
According to scientists, “Visible light makes up 43 per cent of solar energy compared to only 5 per cent possessed by UV light.” Therefore, creating a method to capture energy from the visible light spectrum can prove extremely helpful and efficient in producing more electricity from the same amount of sunshine. This means that some day, we will need less solar panels for powering the average home.
With breakthroughs in battery technology as well, the world of renewable energy is looking rather exciting for the future. Lithium-Ion (Li-Ion) batteries have been dominating the electric car space and slowly seeping into the home and business renewable energy market. According to a comparison chart at Ultra Life Corporation, not only are Lithium batteries superior with specs and overall capability, they’re also much lighter than their Lead Acid counterpart.
The only thing holding back Li-Ion batteries seem to be the price. With almost 3x the price of conventional batteries, Li-Ion batteries are out of reach for most projects.
Non-the-less, solar and wind power are becoming more affordable and available to the general populous as affordability soars and prices go down due to cheaper materials. Mega projects have been under development in various countries and even on waters. Many water based projects have emerged after the realization that water offers a cooler mechanism for managing the heat buildup from a typical ground based installation.
According to the Solar Energy Industries Association, a document outlining the Major Solar Projects List has recently hit the public waves. Showing projects of 1MW (Megawatt) up to several GW (GigaWatt) projects.
