The more light a solar panel`s active elements absorb, the more power it produces. So, researchers have now replaced a two-step process for producing black silicon - highly efficient materials that reflect almost no light - with one.
Solar power has come to the rescue of terrorised womenfolk in Kamduni village on the outskirts of Kolkata who had stopped going out of their houses after dusk after a 20-year-old girl was brutally gangraped and killed.
Ahead of Chinese President Hu
Jintao`s state visit here, his American counterpart Barack
Obama, under a "Buy American" provision, has blocked the
Pentagon from buying solar panels with a `Made in China` tag.
Scientists have discovered a new technology of ‘self-dusting solar panels’ that could increase the efficiency of producing electricity from sunlight and reduce maintenance costs for large-scale solar installations.
