Humans have been trying to harness the sun’s energy for most of history, but it was the invention of the first photovoltaic cell by French physicist Edmond Becquerel in 1839 that finally made solar energy possible on a grander scale.
Since then, solar has come a long way.
Not only has the cost of producing solar panels dropped like a rock, manufacturers are now routinely pumping out new innovations such as flexible solar cells, ultra-thin cells, and transparent photovoltaic windows. These could be game-changers for the industry, adding to the already incredible 39% annual growth occurring in U.S. solar capacity between 2013-2017.
This infographic comes from SaveOnEnergy, and it covers the science behind how solar panels work.
While it is fairly technical, the handy animations will help you understand the principles behind photovoltaic cells in no time at all.
