Could this be the world’s most efficient solar electricity system?

Using military technology and a zero-emission engine invented by a 19th-century Scot, Swedish firm seeks to revolutionise solar energy production By: Jeffrey Barbee A new solar electricity generation system that developers claim is the most efficient in the world, is being tested in South Africa’s Kalahari desert. The Swedish company behind the project – which […]

Stanford’s Solar Cell Turbocharger Could Boost Solar Power Output by 50%

Scientists at Stanford University have improved the efficiency of a revolutionary solar cell by around 100 times. Unlike standard photovoltaic cells, which only capture light energy, Stanford’s new device captures both light and heat, potentially boosting solar cell efficiency towards 60% — way beyond the 30-40% limit of traditional silicon photovoltaic solar cells. This new […]
