Abstract :
Details of the design of the POWER silicon solar cell as well as process sequences are given for both a high efficiency and low cost approach. The status of the technological developments is outlined. Computer-based model calculations demonstrate the far superior performance of this design with respect to conventional structures, particularly as a starting material with small diffusion lengths. Results of a ray tracing analysis of the POWER structure with respect to optimum groove angles are also presented
