Next Generation of Cheap Solar Cells
****Since all the comments seem to be either 100% positive or 100% negative about this solar technology i would like to clear up some some misconceptions. First of all I’d imagine that takes years to set up the the precision equipment for 2 of the largest solar panel manufacturing plants in the world and be able to print solar photo cells as fast as newspaper. After the plant was completed in 2007 the first focus was on commercial uses and their first costumers where municipal utility companies. This sounds to me like a good business tactic to help you establish a successful business from the start. Next they started offering it to electrical contractors as part of a beta testing process so they can work out the kinks that arise from scaling down their panels from large commercial ones to the ones that you can use on your house. That is where were at today. After the beta testing they will start offering them to the general public. Their website even has a place to enter your email address to be notified when this technology will be available to you the home owner. Its a process and that apparently some people out there believe happens over night. This company immediately got more financial backing then needed. Google is one of the biggest investors so I believe its all legitimate. There are two benefits from the use of alternative energy. It will save you money but also it means that energy produced is done so with out creating pollution. This is good for everybody. Even though the technology isn’t yet available for you to install on your home to help save money the fact that utility companies use it to create energy still means means less pollution for us all. . ***** New technology uses cheaper materials instead of expensive silicon crystals. These new solar cells are projected to cost 1/10th of what the more expensive silicon cells cost.

Solar Revolution – Sphelar : Spherical Solar Cell : DigInfo
http://movie.diginfo.tv DigInfo News
Embracing the move towards renewable energy sources, Kyosemi have revolutionized the design of the traditional solar cell, increasing it’s power generation efficiency and paving the way for innovative applications and a more economical use of raw materials. Sphelar is a spherical micro solar cell, which unlike traditional flat solar cells, can effectively harness reflected and diffused solar light as well as direct light from all directions. Each cell, is 1 to 1.5 mm and can be connected in parallel or in series, allowing for a limitless range of shapes and uses including flexible solar cells, round solar cells, or power-generating windows for buildings or offices while maintaining a certain level of transparency. Also, compared to the production process for traditional solar cells there is a dramatic reduction in the amount of wasted silicon. “In the process of producing spherical spolar cells, molten silicon is used. It’s dripped from an elevated position, and crystallizes as a sphere in mid-air, so using this process no silicon is wasted in the production of solar cells.” Kyosemi have also developed the SphelarVoice which is a battery-free wireless audio optical information system that receives information via infrared rays. The SphelarVoice uses an array of LEDs to emit a light signal which is recieved by the solar cells, converted into an electrical signal on the battery-free wireless handset and sent to the speaker.
