Some of the Latest Solar Energy Technologies
Solar energy is the most natural form of energy that is available to us free of ongoing cost. Over the ages man has used the solar energy to harness the energy from the sun to produce the energy to keep them warm.
Solar energy can be harnessed in a number of ways to help mankind. But the solar harnessing has not reached its heights till now when man is feeling the pinch of the lost fossil fuels it has been using so excessively.
There are a few latest solar technologies that are currently being talked about. One such technology is for Inkjet printer technology .
The engineers from the Oregon State University a "CIGS" (copper, indium, gallium and selenium elements) solar device with inkjet printing that has revolutionized the way to work in the office as well as the home. This new technology cuts off the pollution and waste as much as 90%. Further research is required however various low cost high performance thin solar cells will be possible in the coming years.
The advantage of this type of product is the dramatic reduction in the waste that was otherwise produced in the earlier models said by Chih-hung Chang a leader in the field. The inkjet technology does not use the chemical compounds deposit on the pattern rather it uses a very low cost techniques to produce the pattern. This work has been published in professional journals with patents applied for the discoveries.
Another important discovery is that of Organic photovoltaic cells .
Assistant professor Qiquan Qiao at SDSU's Department of Electrical Engineering and Computer Science said that these organic solar cells are less expensive than the traditional solar harnessing electricity technologies. They are also working on organic light emitting diodes. The beauty of these cells is their capacity to be produced at low cost and more energy. These cells are manufactured by fabricating material with a less expensive solution resulting in a more renewable energy and greener world. This ease of production lowers the cost to a significant amount.
A new comer in this field is gold plated solar cells developed by a group of researchers at the University of Warwick. At first it might appear that this would not be cheap but the thickness of gold only of the order of 8 billionth of a metric. The ultra low thickness of the plates it viable even at today's high price of gold as the gold needed to fabricate one square meter is only £ 4.5. This relatively low cost can be recouped while delivering superior flexibility in innovative products.
