Our #SolarButterfly has high-efficiency solar cells produced by LONGi – our Platinum Sponsor and our cells are converting 25% of solar of the sunlight into electricity. Many people says that we will never reach more energy, but in Uppsala they are doing research about tandem solar cells and they believe that in the future we may see 40-45% of efficiency.

Learn more about the efficiency of solar cells from Marika Edoff, Professor, Leader of the division of Solar Cell Technology.
