Abstract
Solar cells efficiency forecasts have been carried out from the very beginning of photovoltaic (PV)
converters in order to guide research activities. Revising the topics of efficiency limits is pertinent
because there are more than one attempts in developing new concepts for solar cells towards obtaining a
higher efficiency. The paper reports a comparative survey of theoretical limits of new proposed nanoscale
converters - known as third generation- multi quantum well tandem, intermediate bands cells and
up/down converters. In our studies we use numerical simulations.
