Searching for promising new perovskite-based photovoltaic absorbers: the importance of electronic dimensionality
TL;DR: In this article, the authors show that perovskite-based solar cells should have a high electronic dimensionality, because of barriers to isotropic current flow, enhanced electron/hole effective masses and fundamentally deeper defect states.

Kyle M. McCall,Constantinos C. Stoumpos,Svetlana S. Kostina,Mercouri G. Kanatzidis,Bruce W. Wessels +4 more
TL;DR: In this article, the optical and electronic properties of single crystals of the widebandgap semiconducting defect halide perovskites A3M2I9 (A = Cs, Rb; M = Bi, Sb) have been investigated.
Journal ArticleDOI
Can Pb-Free Halide Double Perovskites Support High-Efficiency Solar Cells?
TL;DR: It is demonstrated that the combination of Ag(I) and Bi(III) leads to the wide indirect band gaps with large carrier effective masses owing to a mismatch in angular momentum of the frontier atomic orbitals, which can be overcome by replacing Ag with In or Tl; however, the resulting compounds are predicted to be unstable thermodynamically.

Point defect engineering in thin-film solar cells
TL;DR: In this paper, the evolution in the understanding of point defect behavior from Si-based photovoltaics to thin-film CdTe and Cu(In,Ga)Se2 technologies, through to the latest generation of halide perovskite (CH3NH3PbI3) and kesterite (Cu2ZnSnS4) devices, is reviewed.

Ferroelectric Materials for Solar Energy Conversion: Photoferroics Revisited
TL;DR: The application of ferroelectric materials (i.e. solids that exhibit spontaneous electric polarisation) in solar cells has a long and controversial history as mentioned in this paper, and the recent successful application of inorganic and hybrid perovskite structured materials (e.g. BiFeO3, CsSnI3, CH3NH3PbI3) emphasises that polar semiconductors can be used in conventional photovoltaic architectures.

Organometal Halide Perovskites as Visible-Light Sensitizers for Photovoltaic Cells
TL;DR: Two organolead halide perovskite nanocrystals were found to efficiently sensitize TiO(2) for visible-light conversion in photoelectrochemical cells, which exhibit strong band-gap absorptions as semiconductors.
Journal ArticleDOI
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.
