Bio-based solar cell developed by the researchers in Germany by embedding the two proteins photosystem 1 and 2, which in plants are responsible of photosynthesis, into complex molecules developed in-house, thus creating an efficient electron current. In leaves, the photosystems 1 and 2 utilise light energy very efficiently; this is required for converting carbon dioxide into oxygen and biomass. The Bochum researchers' bio-based solar cell, on the other hand, generates
According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, solar, biomass, and wind "units" provided 694 MW of new electrical generating capacity last month or 99.3% of all new generation placed in-service (the balance of 5 MW was provided by oil.) Twelve new solar units accounted for 504 MW or 72.1% of all new electrical generating capacity in October 2013 followed
China's increase in renewable energy is on course to surpass the European Union, the United States and Japan combined, says the International Energy Agency. In its annual World Energy Outlook released Tuesday, the IEA said China will be the strongest driver in the worldwide trend in which renewable energy is expected to account for almost half of the increase in global power generation by 2035, China Daily reports.

For many years scientists and engineers have been trying to provide low-cost solar energy by developing a cheap solar cell that is both highly efficient and at the same time simple to build, enabling it to be mass produced. Now, the team led by Empa researcher Ayodhya N. Tiwari has made a major leap forward: the researchers are presenting a new manufacturing technique for CIGS solar cells, in which tiny
Sun-starved residents of a remote Norwegian village unveiled an ingenious mirror system Wednesday to bring natural light to their mountain valley home and liberate them from darkness that envelops them six months a year. The mountains surrounding Rjukan village have deprived its 3,500 inhabitants of direct sunlight for six months every year, until local artist Martin Andersen revived a century old idea to reflect it with mirrors. "From now we'll
The use of solar panels to produce hot water is standard practice, but researchers at the Madrid Universities Carlos III and Politecnica suggest that they may also be used to provide large offices with heating in the winter and AC in the summer. Their proposal involves the incorporation of solar collectors into a gas-based cogeneration system with an absorption machine, which would reduce both energy expenditure and carbon dioxide emissions.
