Abstract :
At ISE, a research project has been carried out which aims at the development of single crystalline solar cells of high efficiency. For this task a clean room laboratory for solar cell processing has been established, various measuring stations for the characterization of processes and cells have been set up, and a processing sequence for the manufacturing of such cells has been established. All systems and all processes are working well. The highest efficiencies (AM1.5) obtained to date are 21.1% for FZ-, 19.3% for CZ-, and 16.2% for MC (multicrystalline)-silicon
