Recent technoiogicai advances in front-surface texturing using so-called "black silicon" light trapping techniques,back-surface passivation with PERC approach,as well as p-type polycrystalline silicon (multi-Si) grown by seeded directional solidification method,have resulted in the solar energy conversion efficiency of multi-Si PV cells being significantly improved,and made it possible to reach over 20% conversion efficiency in mass production scale.The manufacturability of such multi-Si cells has been studied on the mass-production platform at JA Solar.We found that multi-Si PV cells with averaged conversion efficiency over 20% can be practically realized by combining JAs proprietary light trapping technique with PERC structure using wafers sliced by either conventional slurry cutting or diamond-wire saw.
