Solar Cell

HyperSolar intends to produce a thin, flat, clear solar concentrator, that could boost the...

Solar cells are the most expensive part of a solar panel, so it would follow that if panels could produce the same amount of electricity with less cells, then their prices would come down. In order for panels to be able to do so using existing cell technology, however, they would need to get more light to the fewer cells that they still had. Mounting the panels on the end of vertical poles to get them closer to the sun is one possible approach, that might work in the town of Bedrock or on Gilligan’s Island. A better idea, though, is to apply a clear layer of solar concentrators to the surface of a panel – and that’s just what HyperSolar intends to do.  Read More

Over the past several years, a number of companies and institutions have been developing technologies that could allow windows to double as solar panels. These have included EnSol’s metal nanoparticle-based spray-on product, RSi’s photovoltaic glass and Octillion’s NanoPower window. Last September, Maryland-based New Energy Technologies joined the party by demonstrating a 4 x 4 inch (10.2 x 10.2 cm) prototype of its SolarWindow product. This Tuesday, the company unveiled a working 12 x 12 inch (30.5 x 30.5 cm) prototype, which takes it significantly closer to becoming commercially-viable.  Read More

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have come a step closer to the development of a commercially-viable full-spectrum solar cell. Traditionally, due to their limited band gap (energy range), semiconductors used in solar cells have only been able to respond to a certain segment of the solar spectrum – this segment varies, according to the semiconductor. Some cells have been created that respond to everything from low-energy infrared through visible light to high-energy ultraviolet, but these have been costly to produce and thus unfit for common use. The new cell, however, responds to almost the entire spectrum, and can be made using one of the semiconductor industry’s most common manufacturing processes.  Read More

Honda Soltec announces smaller, more efficient thin film solar cell design

A few years back we reported on the establishment of Honda Soltec, a Honda subsidiary devoted to the development of thin-film solar technology. This week that same group announced that it would be releasing a new thin-film cell that will rank among the world's most efficient with an expected module conversion efficiency of more than 13%.  Read More

An antireflective film inspired by moth's eyes has been shown to improve the efficiency of...

In order for a solar cell to be as efficient as possible, the last thing it should be is reflective – after all, light should be getting absorbed by it, not being bounced off. With that in mind, a few years ago a group of Japanese scientists set out to create an antireflective film coating for use on solar cells. What they ended up creating utilizes the same principles that are at work in one of nature’s least reflective surfaces: moth’s eyes.  Read More

Researchers at the University of Buffalo have announced a breakthrough that promises to im...

Researchers have made a two-fold breakthrough in advancing renewable energies with the development of a light sensitive dye which transfers electrons more efficiently than conventional technologies. The new dyes stand to be used in solar electricity generation and in creating hydrogen fuel, which in the past has proven expensive and energy hungry.  Read More

Researchers at the University of Twente's MESA  Institute for Nanotechnology has allowed f...

In a new, more efficient approach to solar powered microelectronics, researchers have produced a microchip which directly integrates photovoltaic cells. While harnessing sunlight to power microelectronics isn't new, conventional set-ups use a separate solar cell and battery. What sets this device apart from is that high-efficiency solar cells are placed straight onto the electronics, producing self-sufficient, low-power devices which are highly suitable for industrial serial production and can even operate indoors.  Read More

The GO Collection of solar charging clothing from Silvr Lining

Portable solar chargers like the U-Powered solar charger from Kiwi Choice are a handy way to keep mobile devices like smartphones, cameras and media players topped up with electricity while on the go. But if you’re looking for a more convenient way to carry a solar charger with you then the GO Solar Power Collection line of clothing from Silvr Lining could prove a good fit. It comprises a range of clothing items that feature pockets to house solar panels to charge up mobile electronic devices.  Read More

Sony's dye-sensitized solar cell windows combine smart engineering with beautiful screen p...

At the Eco Products 2010 exhibition in Tokyo this past weekend, Sony showed intentions to bring new meaning to the phrase "flower power" with this beautifully designed Hana Mado, or "Flower Window." The device is actually a dye-sensitized solar cell (DSSC) which converts light into electrical energy.  Read More

An Oriental hornet, whose yellow and brown exoskeleton is able to turn sunlight into elect...

It’s no big mystery why turtles and other reptiles bask in the sun – being cold-blooded animals, they’re gathering heat to warm their bodies, so they can be active. Recently, however, scientists from Israel and the UK discovered that the Oriental hornet has been putting a “high-tech” spin on that model... the outer layers of its body work as a natural photovoltaic cell, converting sunlight to electricity. The scientists then proceeded to create a cell of their own, using the hornet as their inspiration.  Read More
