Is Gold Used In Solar Panels

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.

Is gold used in solar panels.

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. Albert einstein s accurate description of the photovoltaic effect in 1905 was a major benchmark in solar power development but it took until the 1950s for an actual improvement to be seen in solar panels. How gold increases the efficiency of solar panels silver is a necessary component of today s 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.

If you ve ever seen a solar panel then you have probably noticed that they are typically blue or black in color. These first efforts were constructed with gold coated selenium. Efficiency of solar cells effects the number of cells solar panel will use. However these aren t the real gold standard of solar panels pun intended.

But thanks to researchers at stanford university solar panels in the near future may incorporate gold to improve performance and efficiency. In august 2018 researchers from hokkaido university in japan studied the efficiency of gold solar cells. The average size of a solar panel is about 1 8 square meters. These were a hot item a few years ago and the price was very low.

Progress stalled at that mark for decades. Todays cells average about 17 mono cells get better efficiency will cost more. However recent research coming out of the netherlands has spotted a red flag to relying on solar panels as a panacea for global. Conventionally designed solar panels are made up of cells that absorb solar energy.

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