Shanhui Fan, Aaswath P. Raman and Linxiao Zhu of Stanford, together created cooling capabilities in the form of a transparent overlay. Solar cells lose efficiency at converting sunlight to electricity as they get hotter, so the transparent overlay radiates heat away from the solar cells, and even in full sunlight, assisting the cells to retain their conversion efficiency.

Cooler solar cells = more photons converted into energy!

Made of patterned silica material, the transparent overlay allows the solar cells to be powered by sunlight, while capturing and radiating away the heat as infrared rays. Also called “radiative cooling” by the inventors, the group published works last year in Nature about their ultrathin material that radiated infrared heat rays directly back toward space without warming the atmosphere – the same principles were applied to the solar cells to increase solar energy conversion efficiencies. During testing on Stanford’s roof, the new transparent overlay allowed visible light to pass through the cells, also cooling the absorber by up to 23 degrees Farenheit, which is a significant increase in cell efficiency by more than 1%.

 

The inventors believe they can scale their project for commercial and industrial use, and recommend that their transparent overlays be used in dry and clear environments.

We’ve pulled out the statistics you’d like to see.

Australian energy consumption overview:

  • Total Australian energy consumption dropped by 1% (to around 5,830 PJ)
  • Australia’s energy productivity (GDP / energy consumption) rose by 4%
  • Energy use declines in electricity generation and manufacturing
  • Consumption in mining and transport energy use rose
  • Coal production and exports continues to grow
  • Oil consumption dropped by 1%

Australia’s consumption of wind, gas and solar energy rose, with overall renewable energy generation increasing by 12% and accounting for around 6% of Australia’s energy use.

Oil continued to be the largest primary energy source in Australia, calculated at 38%, followed by coal at 32% and natural gas at 24%.

Australian Energy Consumption by Energy Type

Australian energy production

  • Production of black coal increased by 8% (to 11,807 PJ), encouraged by new capacity for export markets
  • Production or uranium dropped by 38% (disruptions at Ranger and closure of Honeymoon mines)
  • Production of oil fell by 5% (declining production at ageing fields outweighed new supply)
  • Lower uranium and oil production outweighed growth in black coal
  • Energy production dropped by 4% (to 18,715 PJ)
  • Production of natural gas grew by 2%

Australian electricity generation

Electricity generation further declined by 1% to 894 PJ, due to continued decline in industrial and residential electricity demand, and is offset in part by continued growth in off-grid generation.

Although coal-fired generation declined by 5%, coal remained the largest source of electricity generation in Australia, at 61%. Natural gas comprised 22% of total electricity generation, with renewable energy comprising 15% of total generation in Australia. Majority of the growth continued to be seen in wind and solar energy. For the first time, the share of hydro energy fell below 50%.

Australian energy trade

There was a slight 2% growth in energy exports (to 15,658 PJ), due to the fall in uranium and crude oil exports. LNG exports also dropped slightly. Imports fell by less than 1% (to 2,275 PJ), with the decline in crude oil imports largely offset by a rise in the import of refined products.
