thin multicrystalline silicon-based solar cells

The efficiency of a solar panel is given by the percentage of the sun’s light that is being turned into electricity. The US National Renewable Energy Laboratory (NREL) innovated a new thin film solar panel that just broke the world’s efficiency record, reaching 19.9-percent.

“The copper indium gallium diselenide (CIGS) thin-film solar cell recently reached 19.9 percent efficiency in testing at the lab, setting a new world record.” Treehugger noted.

Traditional silicon based solar panels may have a hard time when these multicrystalline silicon-based solar cells are going to be produced.
