Polycrystalline silicon films are formed on glass via diode laser crystallisation, creating large crystal grains up to 1 mm wide and 10 mm long. Solar cells are formed employing a rear point contacting scheme achieving cell efficiency of 8.4% with open-circuit voltage of 557 mV. Simple optimisation of the contacting scheme is expected to enable over 10% efficient cells in the near future.
