Kyocera offers details on solar cells used by 2010 Prius

Want to know more about the solar moonroof option that's available on the latest third-generation Toyota Prius for 2010? Read on. According to Tech-On from Nikkei newspaper in Japan, the actual polycrystalline Si cells used by the automaker are supplied by Kyocera and are arranged in six columns and six rows.

Solar cells that work at night?

The Idaho National Laboratory, Microcontinuum, Inc. and Patrick Pinhero from the University of Missouri are developing an exciting new technology which uses "nano-antennas" to capture solar energy. What is especially cool about this new solar technology is that it would operate both during the day and at night by using the leftover radiation after the sun goes down. Each nano-antenna is a spiral as wide as 1/25 the diamete

University at Buffalo: how to deposit zinc oxide thin films for solar cells

Zinc oxide coatings serve a variety of purposes, from LCD displays to contact lenses. For the purposes of green technology, they also could have significant impact on solar cells and even batteries. One potential problem is that in the past, the coatings were deposited at such high temperatures that they damaged the substrate they were being applied to. The University at Buffalo in New York believes that they may have found a solution to that proble

Silicon nanoparticle film can increase solar cell performance

Generally, solar cells on the market today do not produce much electricity from ultraviolet light, instead it is either filtered out or absorbed by the cell, heating the cell. That heat is wasted energy and could even lead to damage to the cell. However, researchers at the University of Illinois have discovered a way to utilize that energy by placing a film of silicon nanoparticles onto the

Ohio State develops dye-sensitive solar cells at 25% the cost of silicon cells

We love solar power due to the fact that it could potentially power your electric car completely carbon free. Well, besides what would be emitted by the creation of the solar cells in the first place, but that topic is for another time. Although solar cells are not efficient enough yet to make it practical to place them on a vehicle of standard size and weight, it makes more sense to make the solar cell part of

New solar cell technology is less efficient but more cost effective

Solar power has long been sought after as a solution to our global energy needs. The reason is rather obvious, as the sun never fails to rise in the morning and set at night. Solar power makes especially good sense where sunlight is abundant. Arid areas which have low populations would make excellent sites for large solar arrays. One problem which always has and continues to face solar is the high price of admission. As long as it is significantly cheaper to use far dirtier methods of power g

Using colored dyes instead of silicon for solar cells

Again, as we pointed out in a previous posting, solar power is likely the most environmentally source of power available, but there are problems associated with it. Currently, solar cells are not cheap enough, nor are they powerful enough to replace much of our existing power generation methods. The fact that they are environmentally friendly alone is

Bush Administration and the DOE helping invest in solar technology

President Bush outlined what he is calling the Advanced Energy Initiative in his State of the Union speech. Part of this initiative includes investment in solar technology. Specifically, the Department of Energy has chosen 13 Industry-Led solar projects. Click here for a list of the companies. The current total investment is $168 million and could increase to $357 million in three years, depending on the individual success of each proje
