"Could be the required conversion from DC to AC electricity?" No, it's the converting the photons from the sun into electrons.

Ted, Do you know what's the cause for its low efficiency? No, it is actual process of turning light energy into electrical energy that has low efficiency. Could it be the required conversion from DC to AC electricity? That too, to be able to connect to the grid (inside the house and outside) but that is a smaller part of the problem. Joe

" Could it be the required conversion from DC to AC electricity?" That is part of it. But the most important part is that not all of the sunlight can be converted. Look at it this way. If it could convert all the light, it would be the blackest black it could be. No shininess. No color at all. Because the colors we see is the light that is reflected from it. The fact that PV cells have color, much less somewhat reflective, tells you they aren't very efficient. " Mobile had the first Mardi Gras even before NO. In some ways," It also has their jubilee. en.wikipedia.org
