Organic Solar Cells and Light-emitting Diodes United
In the past 25 years of research on organic semiconductors, it was thought that organic solar cells and organic light-emitting diodes (OLEDs) could not be combined in a single device. A team of physicists headed by Prof. Koen Vandewal from Technische Universität Dresden has now succeeded in manufacturing an organic solar cell that simultaneously functions as an efficient OLED. Their findings were recently published in the internationally renowned journal Nature Materials.

Healthy Light - LED Technology for Health and Care Applications
The right light, at any time during the day or night, is absolutely essential for health and well-being especially in health and care applications. Peter Haumer, Head of Technical Sales at Lumitech/Kiteo reveals why, besides full spectrum and high color rendering, mimicking real daylight conditions with extended daylight curves, a direct and an indirect component (CCT 1.800–16.000 K), are essential. The article discusses the benefits that can be derived from special colors for medical staff, patients and residents.

Well-Being, Light and Exhibition Lighting
Commentary from LpR 71: Well-being is the state of feeling healthy and happy, a good or satisfactory condition of existence, including the emotional and psychological sphere. In 1810, Goethe published a theory based on a human-based approach, combining visual appearance with harmony, culture, sensations and psychology. His color wheel was entitled "allegorical, symbolic, mystic use of color" and was composed of six hues, i.e. red (the beautiful), orange (the noble), yellow (the good), green (the useful), blue (the common) and violet (the unnecessary). The position on the wheel was harmonically relevant and in particular the colors in opposite position generated a strong psychological contrast and were called "opposite colors". Primary colors were yellow, blue and red, and the opposites were green, violet and orange, respectively. Goethe's wheel and the particular matching of opposites soon became popular and was used by the Impressionism movement, especially by Vincent van Gogh and Claude Monet. In this artistic movement, the special impact given by the combination of opposite colors were deliberately aimed to create special psychological effects and sensations.

Tech-Talks BREGENZ - Dr. Maja Grubisic, Researcher, Free University Berlin & Leibniz-Institute
Awareness of the ecological impact of technologies is becoming more important since climate change due to industrialization cannot be denied. LED lighting is one of the technologies that is deemed as a contributor in helping to reduce the impact caused by wasted energy. Unfortunately, light pollution, due to inefficient energy usage, is not the only problem. Besides the more recognized pollution from pesticides and chemical pollutants, light pollution also disturbs ecology and wildlife. Dr. Grubisic, Researcher at the Free University Berlin & Leibniz-Institute, has been working on this problem for more than five years now. She has written an article, also in this issue, concerning this. At the LED professional Symposium she was also good enough to grant this interview, providing some background information, explaining why light pollution is such an issue in biology and why this topic should be of concern to all of us.
