When it comes to optimizing climate-friendly energy generation techniques, chemical research is also very much in demand. Merck, for example, has developed a process for increasing the usable area on solar cells so that the electricity yield can be raised. The focus here is on an innovative etching paste, which can be used to electrically isolate the sides of a solar cell from each another.
