Quantum physics make hybrid semiconductors glow Hybrid semiconducting materials have quantum properties capable of bringing significant changes to light-emitting diode lighting and monitors, along with photovoltaic solar cells, researchers at the Georgia Institute of Technology report. Physical chemists worked with halide organic-inorganic perovskite (HOIP), which combines a crystal lattice wi... » read more

Boosting silicon solar cells According to Stanford researchers, stacking crystalline perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell. The researchers reminded that silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25 percent for 15 years. One inexpensive wa... » read more

Spray-on power In a discovery that could help cut the cost of solar electricity, a team of scientists at the University of Sheffield has fabricated perovskite solar cells using a spray-painting process. The researchers had used the spray-painting method previously to produce solar cells using organic semiconductors - but using perovskite is a major step forward, they asserted. Efficient ... » read more
