Is Gold Used In Solar Panels

Gold solar cells it is possible to construct solar panels out of less common materials.

Is gold used in solar panels.

17 volts is the rated voltage of most 12 volt panels used panels that are visibly brown in color see photo below are probably surplus from the carrizo solar power plant in california. Conventionally designed solar panels are made up of cells that absorb solar energy. The average size of a solar panel is about 1 8 square meters. What they found shocked their colleagues and the solar industry at large.

If you ve ever seen a solar panel then you have probably noticed that they are typically blue or black in color. Todays cells average about 17 mono cells get better efficiency will cost more. In august 2018 researchers from hokkaido university in japan studied the efficiency of gold solar cells. But thanks to researchers at stanford university solar panels in the near future may incorporate gold to improve performance and efficiency.

How gold increases the efficiency of solar panels silver is a necessary component of today s solar panels. The panels attached to the international space station are gold in color but what s the reason for this difference in color and does it lead to any performance differences in the harnessing of solar energy. Given that there are 1 000 000 square meters in a square kilometer it would take about 11 1 million grams or 11 1 tons of silver to. These first efforts were constructed with gold coated selenium.

Solar energy is one of the sources of renewable energy that is being looked to in order to help us reduce our co 2 emissions and power our world in a way that is cleaner and more sustainable than using fossil fuels. These were a hot item a few years ago and the price was very low. However these aren t the real gold standard of solar panels pun intended. Poly cells are less efficient less cost.

Progress stalled at that mark for decades. For a 12 volt panel multiply your current by 17 volts to get watts.
