TL;DR: In this paper, a GaAs-based top tandem solar cell structure was bonded to an InP-based bottom tandem cell with a difference in lattice constant of 3.7%.

TL;DR: In this article, a comprehensive investigation of the luminescent properties of carbon nitride polymers, based on tri-$s$-triazine units, has been conducted, and the spectral, thermal, and temporal features of the photoluminescence can be satisfactorily described by the excitation and radiative recombination of molecular excitons, localized at single tri-$ s$-tripazine units.

TL;DR: In this paper, an extremely thin light absorber consisting of an In2S3 layer (∼20nm thickness) and its interface region with a transparent CuSCN hole conductor was realized by wet chemical preparation on arrays of ZnO nanorods.

TL;DR: In this paper, the performance of small area solar cells depended critically on the local absorber layer thickness (d local ) of solar cells with I extremely thin absorber was changed between 10 nm and 70 nm.

TL;DR: A dye-sensitized solar cell was built with an electrode consisting of ZnO nanorods with a mean diameter of 80 nm instead of the commonly used nano colloidal TiO2 substrate as discussed by the authors.
