GUILDFORD, England, July 2, 2018 — A technique for producing high-performance inverted perovskite solar cells, called solution-process secondary growth (SSG), was shown to increase the voltage of inverted perovskite solar cells by as much as 1.21 V. Inverted planar perovskite solar cells can simplify device structure and reduce costs, compared with conventional solar cells. However, lower open-circuit voltages in perovskite cells can result in lower power-conversion efficiencies (PCEs) than in conventional cells. The SSG technique reduces nonradiative charge-carrier recombination — a process whereby energy...Read full articleRelated content from Photonics MediaARTICLESFabrication Method Paves Way for Large-Scale Perovskite ProductionA simple, synthetic process for fabricating stable perovskite solar cells has overcome a preventative challenge to large-scale production, and, as a result, to product commercialization.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied.
