In this contribution, we report the first results on the application of hydrogenated microcrystalline Si1-xGex (μc-Si1-xGex:H) as bottom cell absorber in triple junction solar cells. It has been demonstrated that μc-Si1-xGex:H films prepared by PECVD in a composition range x~0.1-0.2 show an enhanced infrared response in a p-i-n single junction structure as compared with the conventional μc-Si:H (x=0)...
It is necessary to remove chlorine efficiently from municipal waste plastics (MWP) that contain polyvinyl chloride (PVC) and other plastics containing chlorine. In this article we consider thermal degradation liquefaction technology. In Japan, the chlorine content of reclamation oil products must be kept below 100 ppm owing to the quality standard for pyrolysis oil. Liquefaction dechlorination technology...
