3D Solar Cell Prototype will be Coming Soon

Solar3D plans to launch 3D solar cell prototype at the end of this year which will be the start before launching into the commercial market for the next one or two years. 3D solar cell technology is claimed to be more efficient and less expensive.

3D solar cell technology was patented by Solar3D in November 2010. In 2011, Solar3D will improve their technology by designing the elements of light-trapping of solar cells, maximize efficiency, and to design the micro-structure of three-dimensional photovoltaic cells. The next step is for the fabrication of prototype models.

Actually, the 3D solar cell work using micro-photovoltaic structures that will trap sunlight then bounce the photons around and then turn into electrons. This can be described as a prism that captures the light to produce a few reflections.

If the breakthrough can be successfully commercialized , it might change the market of solar cells that already exist today.

UK's Largest Solar Housing Project over Fuel Issue

A British housing authority plans to install solar panels at least on 650 homes in 2012. The joint project between South Yorkshire Housing Authority and SolarCentury to build solar residential on 10 percent of its 4,000 of existing properties.

The project is expected to build solar housing which a house would be able to provide 30 percent of electricity needs, or about 1410 kWh for a year. If calculated by the cost, this could save up to £ 130 per year. It also give advantage for the residents to sell back to the grid of premium price that they get for electricity.

In addition, the scheme also expected to reduce 350 tons of emissions produced in each year. SolarCentury party states that revenue will go back into the wider benefits such as cuts energy cost and increasing job opportunities. They argue that the feed-in tariff rates are good for retrofitting properties so that solar panels can also be applied to older houses.

UAE Solar Energy Desalination Plant for Friendly Results

UAE is the country that must meet the water needs with the desalination of sea water. They are currently testing the use of solar energy to run a desalination plant to reduce the adverse effects of carbon from fossil fuel use.

Seawater desalination processes using fossil fuels which until now carried out by countries such as UAE and Saudi Arabia has felt impacts which is not good for the environment in the desert and no small cost to run it. The use of solar energy to run a desalination plant expected to provide a more environmentally friendly and save on operating costs.

As the pilot sites and the trial operation of solar desalination plant is located in Hameem and Sweihan districts of UAE. The units are expected to produce energy up to 1050 kilo-watt/hour.

At present problem to be solved is the residue treatment from desalination plant which thrown back into the sea and make the sea water salinity is higher. This can endanger the ecosystem in the sea. As an example of the current Persian Gulf has become more salty due to the process of desalination. It also gives concern for neighboring countries like Kuwait.

Flexible Solar Panels Reduce U.S. Marines Casualties in Afghanistan

The majority of U.S. marines vital military equipment which run using solar energy have brought many benefits for members of the U.S. marines who served in Afghanistan. National Public Radio reported that the use of solar modules could reduce the number of casualties.

According to service members, new equipment that has been tested in Afghanistan during the end of 2010 has been associated with the U.S. Marines safety with its benefits such as cuts down on supply convoys so it can reduce attacks on the road. Driven generators using solar energy produce a more quiet voice so it does not invite the attention of the enemy.

They also use solar blankets that lightweight, compact, and easy to fold so it can save space. In addition, they also can save the use of diesel fuel to run generators that typically 20 gallons per day to 2.5 gallons per day, according to David Doty, 3rd Squad Leader, with1st Platoon. The Marines were satisfied with the testing equipment using solar energy in their duties, its lightweight and easy to use.

New Record of 55.077 mph Solar-Powered Car

HMAS Albatross Navy Base Airstrips in Nowra , Australia, has been the witness for the breaking record of fastest solar-powered car in the world today by Sunswift Ivy which managed to reach the speed of 88.738 km / h (55.077 mph). Records have also been recorded in the Guinness World Record as the fastest solar-powered vehicle.

Sunswift Ivy is a three-Wheeled Vehicle, the work of the students of the University of New South Wales "(UNSW) beat the previous record ever achieved by the GM Sunraycer in 1987 with the speed of 78 km/h (48.5 mph). The vehicle is made of monocoque carbon fiber body and it has brushless CSIRO 3 phase DC 1800 W motor.

The vehicle use about 1200 W power generate by solar array and a 24.75 kg lithium ion polymer battery pack. But for the record achievement test, the batteries were removed to determine the ability of vehicles that are powered entirely by the silicon solar cells.

Actually the team is optimistic in achieving record can reach speeds of up to 90 km / h but due to unfavorable weather so that they can not make further efforts. Previously, UNSW's Sunswift Ivy also has ever won the category in the Global Green Challenge race in 2009.

Smallest Organic Solar Cell Bring Closer to SolarWindow Technology

Application of technology to make SolarWindow closer to be realized with the discovery of the smallest organic solar cells developed by Dr. Xiaomei Jiang, a researcher from the University of South Florida. Revolutionary solar cells will use both natural and artificial light sources to be converted into electrical energy.

The translucent glass can be coated with a coating SolarWindow at room temperature using a commercially available technologies. Currently, the constraints to make translucent SolarWindow hindered by an unclear solar panel if plated on the translucent windows. This happens because the use of metals and various expensive processes that impede visibility and prevent light from passing through the glass surface. The smallest organic solar cells will be able to remove this constraint.

Mr. Meetesh V. Patel, President and CEO of New Energy Technologies Inc, has stated that this is the first time the progress of ongoing research gives the opportunity to develop an early-scale working prototype and hopes to soon be able to launch it. Technology will be applied at home, office and commercial buildings.

Researchers Develop Organic Solar Cell Performance more Than Double

Researchers at Wake Forest University, Carolina, trying to make organic solar cells to be able to work better by using a layer of optical fiber bristles. An optical fiber called "Light Pipes" stamped on a polymer substrate that form the base of the cell.

Researchers today continue to increase the efficiency of organic solar cells up to 10 percent with a combination of organic chemistry to improve the performance of silicon cells. For apart from the problem of the missing sunlight through reflection, it is necessary to antireflective coating or etch the surface of the cell so that the photon absorption increases.

Light pipes that stand out like a coarse straw surrounded by thin organic solar cells are applied using a dip-coating process, light absorbing dye, and the polymer is sprayed into the cell.

The glass fiber cells tested in the laboratory showed increased absorption of light by the fiber up to half as well as twice as many watt-hours during the day compared with flat panels. This is due to fiber can accept light from various angles.

MIT: Get Lots of Solar Energy in a Little Light

Researchers at the Massachusetts Institute of Technology (MIT) will use a way to concentrate sunlight so they can get a more powerful solar energy up to 100 times than current traditional photovoltaic cells. They use solar funnel with carbon nanotubes - hollow tubes made of carbon atoms to capture and focus light energy.

The findings, published in the journal Nature Materials explaining that the chemical engineer at MIT explained that a photovoltaic cell roofs will has little spots that were tiny photovoltaic cells, with incredibly small antennas (10 micrometers long and 4 micrometers thick) that would drive photons into them. The antennas are made of 30 million carbon nanotubes.

But this technology is still constrained by the price of carbon nanotubes are still high, so hopefully will continue to experience price declines along with the current development of chemical company production capacity. MIT team continues to work to obtain more efficient technologies such as minimizing energy loss due to the flow of excitons through the fibers.

Furthermore, the solar funnel technology can also be applied in the manufacture of telescopes or night vision goggles to concentrate the light.
