NOVELTY - The method comprises partially introducing a semiconductor component into a coating bath, and irradiating the coating bath with radiation using a radiation-emitting device, where the coating bath comprises a liquid or a gel matrix and the radiation-emitting device comprises a deflection component (5) for scattering or refracting the radiation, and performing light-induced or light supported deposition such that the deflection component distributes a metal in the liquid or gel matrix. The radiation is irradiated towards a surface of the semiconductor component.    USE - The method is useful for light-induced or light-supported deposition of metal on a surface of a semiconductor device (claimed) such as a solar cell.    ADVANTAGE - The method is capable of depositing the metal on the surface of the semiconductor device with high throughput in an economical manner thus enhancing quantum efficiency and conductivity of the solar cell.    DETAILED DESCRIPTION - The method comprises partially introducing a semiconductor component into a coating bath, and irradiating the coating bath with radiation using a radiation-emitting device, where the coating bath comprises a liquid or a gel matrix, and the radiation-emitting device comprises a deflection component (5) for scattering or refracting the radiation, and performing light-induced or light supported deposition such that the deflection component distributes a metal in the liquid or gel matrix.
