Three types of solar photovoltaic cells are analyzed herein including devices based on: (1) the use of multiple junctions stacked together and connected in series, (2) the suggested principle of using quantum coherence in intrinsic semiconductor quantum dots embedded in a junction to allegedly break detailed balance, and (3) the theoretical concept known as the hot carrier solar cell which is based on the attempted collection of hot electrons (holes) prior to thermalization. We discuss the inherent advantages and promise of using carefully designed multijunction solar cells and show how these may be improved. In contrast, we show that there are fundamental limitations to both quantum coherent and hot carrier solar cells, the former due to the irrelevance of coherent quantum states in so far as being able to increase either voltage or current and the latter due to the inability to effectively extract, through narrow energy selective contacts, a sufficient number of the widely distributed photogenerated charge carriers. Finally, we offer an analysis of the scalability and discussion about the possible future ahead for solar photovoltaics
