New Material to Increase Solar Cell Efficiency
A team of researchers has come up with a solar cell that produces fuel rather than electricity. A material called gallium phosphide enables the solar cell to produce clean fuel hydrogen gas from liquid water.
To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution; but it is very expensive.
So, researchers were streamlining their search to a semi-conductor material that is able to both convert sunlight into an electrical charge and split water.
The team found gallium phosphide (GaP), a compound of gallium and phosphide, useful in this respect.
GaP has good electrical properties but the drawback is that it cannot easily absorb light when it is a large flat surface as used in GaP solar cells, said the study thatappeared in Nature Communications.
The researchers overcame this by making a grid of very small GaP nanowires, measuring five hundred nanometres (a millionth of a millimetre) long and ninety nanometres thick.
"That makes these kinds of cells potentially a great deal cheaper," said lead author Erik Bakkers from Eindhoven University of Technology, the Netherlands. Cont'd...

Renewable energy boom will mean vastly cheaper electricity
By Lucas Mearian, ComputerWorld: Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity -- and solar power that's less expensive than what fossil fuel-based power plants can produce.
Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion.
That was consensus view from a several keynote speeches delivered at the Intersolar Conference in San Francisco this week.
Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, said that in sun-rich countries, the cost of solar power is already below 5 cents per kilowatt and it will continue to plummet as battery storage systems become more prolific and less expensive. Cont'd...
