With the world’s showroom floors crammed with prototype smartphones promising advanced functions, bigger displays, stunning resolution, wouldn’t you think the biggest crowd-pleasers would dominate? The ultimate attraction in a smartphone, the one that never has to be charged again? This ultimate solution at least has scientists working toward that end, to bring in an easier time where users will not need to worry about the batteries wearing out.

Arunpillai shared a picture 600 - The Modular EV (2) 6 months ago
A six-seater EV - dubbed the '600' - built with low-cost materials, designed by London-based Ian Mann. The modular construction means, it is easy to assemble, it has a low-weight Li-ion battery pack and thin PV cells on the roof.

Arunpillai posted a blog Solar is à la mode 7 months ago
I have been a big fan of solar power ever since I heard about it as as a kid in class 6 or 7. We were taught that we could generate electricity with the light of the sun, which being a never-ending resource was referred to as a “renewable” source of energy. I found it quite fascinating that sunlight could be so ‘powerful’ even as I had no idea how electricity was generated conventionally. And neither did I have any idea over the years it took me to reach the information age to understand the challenges – posed by technology…

May be this information gives an answer: http://news.nationalgeographic.com/news/2005/01/0114_050114_solarplastic.html (2005).http://www.gmagazine.com.au/news/1193/scientists-develop-spray-solar-panels (2009). http://www.gizmag.com/thin-film-turns-windows-into-solar-panels/16058/ (2010).http://www.pcworld.com/article/203998/sprayon_solar_cell_technology_powers_the_future.html (2010).http://nextbigfuture.com/2011/02/spray-on-solar-panels-using-cigs.html (2011). http://www.gizmag.com/quantum-dot-solar-cell-efficiency-record/19922/ (2011). "The process is still in the works – thus far, the prototypes that have been developed can only convert 1% of the sunlight that hits the cell into electricity. The goal conversion is 10%, so there is still quite a way to go. “If it works, I think you could see it being used in three to five years,” explains Korgel http://inhabitat.com/spray-on-solar-cells-energize-almost-any-surface/ And then ask yourself, how much nano production even as semi-product costs and how much time will be need to pass from the lab to industry, which will use rare earth material and transform them to nano stages.

Mitsubishi Chemical Corp has developed a spray-on technology, wherein specific carbon compounds after being sprayed, dry and behave like semiconductors producing electricity from the solar energy. The efficiency is only 10 percent which is lesser in compared to the 20 percent of the conventional type. Yet the Chemical Group believes that through further research it could increase the value to at least 15 percent in the future.

The possibilities for such a spray on technology is immense...just imagine it for a moment, and you can come up with so many cute and wonderful ideas. Why, I might even spray it on my laptop covers and mobile phones, and the batteries can get charged from solar. Endless, exciting possibilities

SoloPower Founders Launch CdTe Thin Film Company
The technology, the company claims, could give cadmium telluride a new lease on life.
Encore Solar says it can lower the cost of cadmium telluride solar modules by 20 percent or more as well as help the technology break through a looming efficiency wall.
Encore wants to produce CdTe modules with electroplating. Currently, CdTe companies like First Solar handle the process through vapor deposition: CdTe vapor is introduced into a vacuum chamber and forms films that become a solar cell.

Solar Could Get Boost From 'Cling Film'
A new study from England suggests that thin, flexible material placed over a large area - much like cling film - can be used to produce more efficient solar cells. This simple and inexpensive manufacturing method, developed by scientists from the universities of Sheffield and Cambridge and reported in the journal Advanced Energy Materials, could revolutionize the way solar cells are made, using polymer (plastic) instead of pricier silicon, and boosting development of solar power.
This film technique was discovered when a mixture of molecules was spread over a surface, much like painting a wall, or a printer laying ink on paper. Scientists noted that the molecules separated, with some rising to the top of the layer and some sinking to the bottom, and in doing so maximized the efficiency of the resulting solar cell. The layers were studied at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory using a neutron beam and X-rays to determine the most efficient combination of molecules.

Compact Linear Fresnel Reflectors for Solar Energy - French physicist Augustin Fresnel showed in the 19th century that a large lens, like the parabolic troughs of the existing solar-thermal plants, can be broken down into smaller sections that deliver the same focus. Mills' design applies this by using a compact linear Fresnel reflector, which allows for greater ground coverage, lower weight and greater durability than precision-shaped parabolic mirrors. They’re not fragile like some other solar technologies. - http://www.dailygalaxy.com/my_weblog/2008/09/can-sunshine-co.html
