Scientists demonstrate how organic dyes work as antennas to help harness, convert light
An international team of scientists has demonstrated a breakthrough in the design and function of nanoparticles that could make solar panels more efficient by converting light usually missed by solar cells into usable energy.(more…)
2-in-1 device also uses supercapacitor to store energy that could power computers and smartphones
UCLA researchers have designed a device that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars.(more…)
The technology of solar energy has progressed dramatically in the last few decades, as it operates with increasing efficiency and at lower costs.
But the matter of how solar panels look remains an obstacle. Most photovoltaic panels are blue or black and cover large portions of buildings with a monotone hue. That might not jibe with your personal taste – or that of your homeowners’ association. It’s a limitation that has hindered the integration of solar energy into some commercial applications. In fact, architects and designers have long requested a wider choice of colors for solar cells to allow them to seamlessly blend into a building’s façade or an electronic system. (more…)
When considering whether to go solar, perhaps the most deciding factor is the cost versus the benefits of converting to solar energy. It goes without saying that solar energy will save you money, but installing a solar power system for your home isn’t exactly cheap. These benefits to installing a solar power system as well as the costs can help you to perform a cost-benefit analysis and decide whether solar energy is right for you. (more…)
UD alum leads Michigan State research team in development of solar concentrator
A team of researchers at Michigan State University, which is being led by a University of Delaware alumnus, has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window.
It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface. (more…)
North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns worth of energy without losing much voltage as “wasted energy” or heat.
Stacked solar cells consist of several solar cells that are stacked on top of one another. Stacked cells are currently the most efficient cells on the market, converting up to 45 percent of the solar energy they absorb into electricity. (more…)
Advanced solution combines big data analytics and weather modeling technology to predict output of individual wind turbines
ARMONK, N.Y., – 12 Aug 2013: IBM today announced an advanced power and weather modeling technology that will help utilities increase the reliability of renewable energy resources. The solution combines weather prediction and analytics to accurately forecast the availability of wind power and solar energy. This will enable utilities to integrate more renewable energy into the power grid, helping to reduce carbon emissions while significantly improving clean energy output for consumers and businesses.

Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth’s land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity with a certain measure of efficiency. For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than silicon-based solar cells, scientists have long believed that the key to high efficiencies rests in the purity of the polymer/organic cell’s two domains – acceptor and donor. Now, however, an alternate and possibly easier route forward has been shown.
Working at Berkeley Lab’s Advanced Light Source (ALS), a premier source of X-ray and ultraviolet light beams for research, an international team of scientists found that for highly efficient polymer/organic photovoltaic cells, size matters. (more…)
