When Will Solar Get Cheap Enough for Everyone to Use?

When Will Solar Get Cheap Enough for Everyone to Use? | Slash's Science & Technology Scoop | Scoop.it

Sascha Humphrey's curator insight, February 6, 2014 8:29 AM

"In Germany, where sensible federal rules have fast-tracked and streamlined the permit process, the costs are considerably lower. It can take as little as eight days to license and install a solar system on a house in Germany. In the United States, depending on your state, the average ranges from 120 to 180 days."


"Is it too ambitious to assume the price of solar continues to fall by 7% per year? On the contrary, if the cost of solar continues at that pace, it will take the U.S. until 2025—13 years!—to match today's cost of solar in Germany. Can anyone honestly claim we'll remain so far behind for so long?"

Perovskite oxides for visible-light-absorbing ferroelectric and photovoltaic materials : Nature : Nature Publishing Group

Perovskite oxides for visible-light-absorbing ferroelectric and photovoltaic materials : Nature : Nature Publishing Group | Slash's Science & Technology Scoop | Scoop.it
Ferroelectrics have recently attracted attention as a candidate class of materials for use in photovoltaic devices, and for the coupling of light absorption with other functional properties. In these materials, the strong inversion symmetry breaking that is due to spontaneous electric polarization promotes the desirable separation of photo-excited carriers and allows voltages higher than the bandgap, which may enable efficiencies beyond the maximum possible in a conventional p-n junction solar cell. Ferroelectric oxides are also stable in a wide range of mechanical, chemical and thermal conditions and can be fabricated using low-cost methods such as sol-gel thin-film deposition and sputtering. Recent work has shown how a decrease in ferroelectric layer thickness and judicious engineering of domain structures and ferroelectric-electrode interfaces can greatly increase the current harvested from ferroelectric absorber materials, increasing the power conversion efficiency from about 10-4 to about 0.5 per cent. Further improvements in photovoltaic efficiency have been inhibited by the wide bandgaps (2.7-4[thinsp]electronvolts) of ferroelectric oxides, which allow the use of only 8-20 per cent of the solar spectrum. Here we describe a family of single-phase solid oxide solutions made from low-cost and non-toxic elements using conventional solid-state methods: [lsqb]KNbO3[rsqb]1[thinsp]-[thinsp]x[lsqb]BaNi1/2Nb1/2O3[thinsp]-[thinsp][dgr][rsqb]x (KBNNO). These oxides exhibit both ferroelectricity and a wide variation of direct bandgaps in the range 1.1-3.8[thinsp]electronvolts. In particular, the x = 0.1 composition is polar at room temperature, has a direct bandgap of 1.39[thinsp]electronvolts and has a photocurrent density approximately 50 times larger than that of the classic ferroelectric (Pb,La)(Zr,Ti)O3 material. The ability of KBNNO to absorb three to six times more solar energy than the current ferroelectric materials suggests a route to viable ferroelectric semiconductor-based cells for solar energy conversion and other applications.

Botulinum toxin or Botox to you and me!

0.00007mg to kill a 70 kg man or woman, and it costs £100 trillion per Kg.

A couple of kilo could kill every human on earth.

Nuclear vs. renewables: Divided they fall | Slash's Science & Technology Scoop | Scoop.it
People who agree that climate change is a dire problem often disagree about how to solve it. In recent months, once-private disagreements have ballooned into a public spat between pro-nuclear and anti-nuclear climate activists. Depending on whom you ask, nuclear power is either “essential” or “ill-suited” to efforts aimed at staving off climate disaster.
