Organic light-emitting diodes (OLEDs) have rapidly grown as one of the leading
technologies for full-color display panels and eco-friendly lighting sources due to their …

Recently, significant advances have been made in understanding and manipulating the
morphology of the active layer in bulk heterojunction (BHJ) organic photovoltaic (OPV) …

Abstract Light-emitting diodes (LEDs), which convert electricity to light, are widely used in
modern society—for example, in lighting, flat-panel displays, medical devices and many …

In lead halide perovskite solar cells, there is at least one recycling event of electron–hole
pair to photon to electron–hole pair at open circuit under solar illumination. This can lead to …

The first advanced textbook to provide a useful introduction in a brief, coherent and
comprehensive way, with a focus on the fundamentals. After having read this book, students …

Most of the light in conventional organic light-emitting diodes is confined to high-refractive-
index layers (such as an organic medium, indium tin oxide and glass substrate) resulting in …

We demonstrate that ordered microlens arrays with 10 μm diam poly-dimethyl-siloxane
lenses attached to glass substrates increase the light output of organic light emitting devices …

New advances offer flexible, low-cost fabrication methods for light-emitting materials,
particularly in display technologies. As researchers continue to develop novel applications …

Progress reports are a new type of article in Advanced Materials, dealing with the hottest
current topics, and providing readers with a critically selected overview of important progress …

We examine the problem of efficiently collecting the photons produced by solid-state single
photon sources. The extent of the problem is first established with the aid of simple physical …
