New Grant Supports Promising Research in Solar Energy

Ujjwal Das, an associate scientist at the University of Delaware's Institute of Energy Conversion, examines a silicon wafer after a thin layer of sulfur - less than 5 nanometers thick - was deposited on the surface. In the background, doctoral students Robert Theisen and Isaac Lam watch a silicon wafer emerge from the atmospheric pressure vapor treatment reactor, where it was treated with hydrogen sulfide and hydrogen selenide gases. The reactor was developed at IEC.

In their quest to improve our ability to capture and distribute the Earth's greatest potential source of power--the sun--scientists are exploring every square nanometer of solar cells, looking for new ways to improve their voltage and efficiency, while reducing costs. The University of Delaware has a distinct

'Hot Spots' Increase Efficiency of Solar Desalination

Rice University researchers (from left) Pratiksha Dongare, Alessandro Alabastri and Oara Neumann showed that Rice's 'nanophotonics-enabled solar membrane distillation' (NESMD) system was more efficient when the size of the device was scaled up and light was concentrated in 'hot spots.'

HOUSTON -- Rice University's solar-powered approach for purifying salt water with sunlight and nanoparticles is even more efficient than its creators first believed. Researchers in Rice's Laboratory for Nanophotonics (LANP) this week showed they could boost the efficiency of their solar-powered desalination system by m

Carbon-Neutral Fuel Made From Sunlight and Air

The research plant is located on the roof of the ETH building on Sonneggstrasse.

Carbon-neutral fuels are crucial for making aviation and maritime transport sustainable. ETH researchers have developed a solar plant to produce synthetic liquid fuels that release as much CO2 during their combustion as previously extracted from the air for their production. CO2 and water are extracted directly fr

The Economic Value of Adjusting the Power Consumption
Since the output of renewable energy such as photovoltaic generation tends to fluctuate, the power system can be viewed as a large-scale complex system with uncertainty. To stabilize the balance of supply and demand of electricity, we need an energy management system to control this. In recent years, energy ma
