Flexible friend: The quantum efficiency of flexible photovoltaic devices in the near-infrared spectral region has been improved by integrating Si nanowire arrays with plasmonic Ag nanoplates. The Ag nanoplates can directly harvest and convert NIR light into plasmonic hot electrons for injection into Si, while the Si nanowire arrays allow light trapping. The flexible devices show excellent durability over 50 flexing cycles.

A strategy for integrating NaYF₄:Yb/Er upconversion nanoparticles as a mesoporous electrode into CH₃NH₃PbI₃ perovskite solar cells makes it possible to operate the cells with near-infrared light. The in situ integration of upconversion materials as functional components in perovskite solar cells offers flexibility for engineering the device architecture and broadening the use of solar radiation.

Unleaded: Bulk single crystals of lead-free perovskites CH₃NH₃SnI₃ and CH(NH₂)₂SnI₃ can be obtained by top-seeded solution growth under an ambient atmosphere. CH₃NH₃SnI₃ acts as a p-type semiconductor, while CH(NH₂)₂SnI₃ behaves as an n-type semiconductor. CH(NH₂)₂SnI₃ was found to be more stable than CH₃NH₃SnI₃ after storage under an ambient atmosphere for one month.

Twisted: Rigid truxenone oligomers with an extended π backbone (see example structure) were synthesized by oxidative dimerization reactions. The resulting extended conjugated systems, which dissolve well in common organic solvents, have large extinction coefficients and low-lying LUMO levels. Their suitability as electron acceptors for organic electronics has been demonstrated in bulk-heterojunction organic solar cells.
