Linear Technology Corporation announces the H- and MP-grade versions of the LT8705. This high efficiency (up to 98%) synchronous buck-boost dc-dc controller operates from input voltages above, below or equal to the regulated output voltage. The LT8705 operates over a 2.8V to 80V input voltage range and produces a fixed 1.3V to 80V output, using a single inductor with 4-switch

China continues to play a major role in strengthening renewable energy infrastructure in Africa. The Asian giant has been lending financial and technical assistance to African countries looking to install solar, wind, and hydro power projects. Tanzania has become the latest beneficiary of financial assistance from China, for a 300 MW wind energy project. China’s Export-Import Bank will provide $136

MIT scientists and engineers have a new twist on phase-changing renewable technology. It combines the most efficient generation of solar steam to date by our favorite energy machine, the sun, and a new graphite-based collection system. This method puts out the lowest optical concentration reported thus far: steam generation at an intensity about 10 times that of a sunny day.

Experts from Sheffield Universitys Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors – but using perovskite is a major step forward. Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. They are now a promising new material for solar cells as
