This study explores the effects of pixel size and spacing when fabricating electroluminescent (EL) multipixel displays. COMSOL simulations identify the impact of pixel dimensions and spacing on electric field distribution and lighting efficiency. Flexible, high‐resolution EL pixel arrays are reverse offset printed, achieving a 96% reduction in pixel ...

Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Speed Scaling with a Solar Cell
AbstractWe consider the setting of a device that obtains its energy from a battery and some regenerative source such as a solar cell. We consider the speed scaling problem of scheduling a collection of tasks with release times, deadlines, and sizes, so as to minimize the energy recharge rate of the regenerative source.
