In this video we look at the progress in the efficiency of various solar cell technologies over the last year. The video covers the detail on the most efficient solar cells and solar panels in 2019. The values of efficiency have been taken from NREL charts. The technologies covered include Dye sensitized, Thin -Film, Poly crystalline Silicon, Mono crystalline Silicon and Multijunction Solar cells. In addition to these, Perovskite and organic solar cell efficiencies have also been listed. Prices of the panels can be found at this link https://youtu.be/HeYvXwU-E38
