Solar cell design with over 50% energy-conversion efficiency
12 hours ago
Solar cells convert the sun's energy into electricity by converting photons into electrons. A new solar cell design could raise the energy conversion efficiency to over 50% by absorbing the spectral components of longer wavelengths ...
Study shows when population pressure increases, food is imported
Apr 13, 2017
The Earth's capacity to feed its growing population is limited – and unevenly distributed. An increase in cultivated land and the use of more efficient production technology are partly buffering the problem, but in many ...
