TL;DR: Geisz et al. as discussed by the authors presented a series-connected, six-junction inverted metamorphic structure with a 1-Sun global efficiency of 39.2% when tuned to the global spectrum.

TL;DR: In this article, high-energy electron beams can significantly alter perovskite properties through two distinct mechanisms: defect formation caused by irradiation damage and phase transformation induced by electron-beam heating.

TL;DR: Metal–Insulator–Metal (MIM) diodes are actively investigated as high-frequency rectifi cation mechanism in suitably designed MIM structures and materials-design rules to help choose suitable materials for the MIM stack that favor the desired rectify behavior are lacking.

TL;DR: In this article, the same microscopic areas of CdTe thin films were used to correlate grain-boundary (GB) recombination by GB “type, including misorientation-based GB types, including coincident site lattice (CSL), other-CSL (Σ = 5-49), and general GBs, which make up ∼47%-48, ∼6%-8, and ∼44%-47, respectively, of the GB length at the film back surfaces.

TL;DR: In this article, the authors review the atomistic theoretical understanding of the physics of grain boundaries in CIGS and CdTe absorbers and show that intrinsic GBs with dislocation cores exhibit deep gap states in both polycrystalline Cu(In,Ga)Se2 (CIGS) and cdTe photovoltaic semiconductors.
