Abstract
In this work, n-type a-Si:H/c-Si heterojunction solar cells were fabricated using mono-like silicon wafers. First, cell efficiency distribution was investigated along a complete mono-like silicon ingot. Advanced electrical characterization was performed in order to understand limiting mechanisms of the final device performances. Fabricated heterojunction cells with the standard industrial compatible process have demonstrated efficiencies comparable to those with our Czochralski grown monocrystalline substrates: over 19% along a large part of the ingot. Moreover, the best wafers were evaluated using our advanced cells process. Very high efficiencies over 21.5% have been obtained, demonstrating the potential of such substrates for very high efficiency solar cells.
