Detailed Balance Limit of Efficiency of p‐n Junction Solar Cells
TL;DR: In this article, an upper theoretical limit for the efficiency of p−n junction solar energy converters, called the detailed balance limit of efficiency, has been calculated for an ideal case in which the only recombination mechanism of holeelectron pairs is radiative as required by the principle of detailed balance.

TL;DR: In this article, the authors present an analysis of such a structure under ideal conditions and prove that its efficiency can exceed not only the Shockley and Queisser efficiency for ideal solar cells but also that for ideal two-terminal tandem cells which use two semiconductors, as well as that predicted for ideal cells with quantum efficiency above one but less than two.

Limiting efficiencies for photovoltaic energy conversion in multigap systems
Antonio Martí,G.L. Araujo +1 more
TL;DR: In this article, the authors used the concepts of angle and energy restriction to emphasize that this limit is independent of the light concentration, and showed that the limiting efficiency of photovoltaic converters with a finite number of cells is higher than previously reported.

Absolute limiting efficiencies for photovoltaic energy conversion
G.L. Araujo,Antonio Martí +1 more
TL;DR: In this paper, the authors extended the generality of those results and introduced new refinements to the Detailed Balance Theory and showed that the cell absorptivity is justified to be equal to the emissivity under bias operation and under certain idealistic conditions.
