An experimental technique is presented for fabricating large surface area semitransparent monocrystalline Si solar cells. The semitransparency is achieved by laser-cutting two-dimensional periodic lattices of ellipses through industrially manufactured Si cells. A novel two-level metal base was invented for minimizing cell breakages during laser cutting. The periodic lattices consist of a large number of ellipses, so as to achieve uniform distribution of the transmitted solar radiation. High efficiencies over 13% are deduced from the I–V curves, recorded under physical sunlight, for all fabricated cells with a 5% transparency.
