Crystalline silicon cell fabrication: Crystalline silicon PV cells are fabricated from the so-called "semiconductor silicon" that is prepared from metallurgical silicon by decomposition of SiHCl 3 or SiH 4 in purity higher than 99.9999%. These solar cells are manufactured by recycling discarded electronic components: the so-called "silicon scraps," which are remelted to obtain a compact crystalline composition. Compared with conventional crystalline silicon cells, the surface recombination of front surface has a greater impact on the performance of IBC solar cell because the front surface is far away from the p-n junction, which is located on the rear side. Written by three internationally renowned experts, this valuable reference profits from results and experience gained from research at the Fraunhofer Institute for Solar Energy Systems. Slab of multicrystalline silicon after growth. The fabrication of our c-Si solar cell starts with a 300m thick, (100) oriented Czochralski Si (or Cz-Si) wafer.
