Optical confinement is essential in order to increase the amount of photogeneration in a crystalline silicon (c-Si) solar cell. Fraunhofer examines the compatible options for wafers created using diamond wire sawing.
N-type high-performance multicrystalline silicon (HP mc-Si) has proved to have an excellent material quality.
This paper presents details of the growth of HP mc-Si, as well as the properties of this material and its use in
the fabrication of high-efficiency solar cells.
