Can solar energy ever be as affordable as fossil fuels? Israeli scientists are researching ways to make solar energy more effective – and affordable – providing a realistic alternative to fossil fuels.
The sun is a powerful source of renewable energy. In fact, it is currently the only energy source capable of supplying the energy needs of the human race, so it’s no wonder that the use of solar energy is increasing. But there are a number of technological limitations when it comes to photovoltaic cells…
Researchers at the The Technion – Israel Institute of Technology in Haifa have developed a new technology that could improve the efficiency of photovoltaic cells by nearly 70 percent.
The Technion team’s method is based on an intermediate process that occurs between sunlight and the photovoltaic cell. The photoluminescence, light emission from any form of matter after the absorption of photons, material they created absorbs the radiation from the sun, and converts the heat and light from the sun into an “ideal” radiation, which illuminates the photovoltaic cell, enabling higher conversion efficiency.
“Today costs of photovoltaics are comparable to fossil fuels,” Rotschild [Assistant Professor at the Faculty of Mechanical Engineering and head researcher of the study] tells NoCamels. “The prices of photovoltaics are dropping every year due to collective effort of the scientific and engineering community. This ensures that solar energy will become significant.”
