Luminescent solar concentrators for building-integrated photovoltaics

Luminescent solar concentrators (LSCs) offer a unique opportunity to ‘invisibly’ integrate semi-transparent photovoltaic architectural elements, such as electrodeless glazing units, into the building envelope. This Review highlights the advancements making LSCs a realistic technology for near zero-energy buildings, along with the remaining challenges and strategies for further device optimization.

Halide perovskites as disposable epitaxial templates for the phase-selective synthesis of lead sulfochloride nanocrystals

Phase-selective approaches, such using reaction-directing groups, are often seen in traditional organic chemistry and catalysis. Here authors use perovskite nanocrystals as disposable templates to drive the phase-selective synthesis of two colloidal nanomaterials, the lead sulfohalides Pb₃S₂Cl₂ and Pb₄S₃Cl₂.

Extreme γ-ray radiation hardness and high scintillation yield in perovskite nanocrystals

It is shown that CsPbBr₃ nanocrystals exhibit good radiation hardness for high γ-radiation doses, as high as 1 MGy. Electron trapping in surface defects limits scintillator applications, but is shown to be suppressed by surface fluorination treatment.

Large-area luminescent solar concentrators based on ‘Stokes-shift-engineered’ nanocrystals in a mass-polymerized PMMA matrix

Stokes-shift-engineered CdSe/CdS quantum dots are used to fabricate luminescent solar concentrators that are tens of centimetres long and do not exhibit reabsorption losses. With efficiencies of over 10% and an effective concentration factor of 4.4, they demonstrate the potential of using Stokes-shift-engineered quantum dots in large-area luminescent solar concentrators.

Reversed oxygen sensing using colloidal quantum wells towards highly emissive photoresponsive varnishes

Colloidal quantum wells have great potential as solution-processed light sources. Here, Lorenzon et al. demonstrate that such colloidal quantum wells can also be exploited as luminescent-sensing varnishes capable of detecting chemical agents through their reversible emission response.

Perovskites cut energy losses

The realization of perovskite nanostructures featuring high emission efficiency and a wide Stokes shift is proving difficult, limiting their impact on luminescent solar concentration technology. Now, engineered exciton routing within multilayered perovskite nanoplatelets may open a path towards high-performing, low-loss devices.

Band structure engineering via piezoelectric fields in strained anisotropic CdSe/CdS nanocrystals

Quantum dots confine electrons to a nanometre length scale, and this gives rise to numerous quantum effects. Here, the authors directly control the excitonic structure of nanocrystal quantum dots by manipulating intra-particle piezoelectric fields.
