How to Make a Solar Cell at Home
19 July 2010 | Solar Power | No Comments
I have seen many sites, writing about the advantages of using solar panels and some of them show you actually how to build solar panels at home. These sites will guide you step by step in building a solar panel, but always for such a project they will tell you to buy solar cells (PV cells). So, I’ve asked myself why don’t we make these solar cells at home using few chemicals and some pieces of glass?
Retinal Implants Powered by Onboard Flexible Solar Cells

Recently, I have read on the internet about a very interesting device and I couldn’t refrain to post about it on MyGreenTreasure. It’s about a photovoltaic chip, able to improve human eyesight (especially for those with damaged photoreceptor cells). These cells are able to capture the light, forming on the retina, the image we look for. Due to the growing in age, or often even from birth, these cells are weaker than it should be and that’s why the problems appear.
Solar Roadways Could Power The Entire World

We all know how hot and how much heat the roads dissipate during summer times. We all have seen the hot road mirage on the highways, where the road seems soaked in a pool of water. Well, what if this heat and energy can, in some way be extracted and stored as electrical energy ? This was the idea that captivated Scott Brusaw’s imagination since childhood. Now, as a grown man, after he acknowledged the dangers of global warming, he came up with the concept that enables him to use this, once lost, energy. After years of development, together with his wife, they introduced Solar Roadways, a company designed for a fully digitized roads, that could ,theoretically, someday power the entire world.
More efficient technology – non-silicon based solar cells
11 July 2009 | Solar Power | No Comments
Large solar cells on house roofs is a quite common sight nowadays in most developed countries. The reason why the technology still isn’t available on a world-wide scale is, of course, the price of the installation. Most of the solar cells on the market today are configured as a large-area p-n junction made out of silicon. But this is about to change. Scientists at the University of California, Los Angeles made a significant technological progress, that promise to lower the price of solar technologies and make it more accessible. Although efficiency levels of 20 percent have already been reached, the processing methods are still costly and “ultimately the cost of fabricating the product makes it difficult to be competitive with current grid prices” noted William Hou, an engineering graduate student at UCLA, member of the research team.
Solar Impulse present a Zero Fuel Solar Airplane
26 June 2009 | Solar Power | No Comments
Yesterday, the 26 of June, represented a milestone in solar and renewable energy developments. It was the day Solar Impulse presented the first solar powered plane to fly both day and night without producing any pollution at all. At the Dübendorf airfield in Switzerland, Bertrand Piccard and André Borschberg, the main characters revolving the project, unveiled the HB-SIA, a prototype airplane, a marvellous piece of engineering, to the public.
