Scientists at the University of Konstanz have developed a measuring device for non-permanent contacting of busbarless solar cells that allows for precise and direct characterization of electrical properties. As each contact finger can be contacted repeatedly over reversibly releasable connections the device allows for accurate measurement of I-V characteristics without requiring subsequent adjustment with correction factors.
The efficiency of solar cells made of CZ silicon decreases by more than 1% in absolute figures under sunlight within a few hours (light induced degradation – LID). At the University of Konstanz a method was developed that makes it possible to stabilize the efficiency of the solar cell at nearly its output level. During production the solar cells are regenerated by either illumination at temperatures of between 100 and 230 degrees or applying voltage. The method can be easily integrated in the conventional manufacturing process and allows for an increase in efficiency by up to 5% rel.
Agronostics Aachen will be an innovative agricultural chemistry start-up operating in the growth market of plant defense priming. Primed plants show enhanced resistance to disease and pests, and increased tolerance to abiotic stress. Taking into account that these threats still destroy ~40% of possible crop yield, defense priming provides a unique opportunity to secure best possible yield.
