    Abstract: A method and apparatus for measuring thickness of a film in a solar cell provides for directing light emitted at multiple emission wavelengths, to a surface of the solar cell. Each emission results in the generation of a responsive photo current. The photo currents are read by a current meter having one contact coupled to a surface of the solar cell and another contact coupled to another surface. The currents associated with each of the different light emissions are identified and the thickness of a film in the solar cell is calculated based on the two currents or associated quantum efficiencies, and associated absorption coefficients. In one embodiment, the film thickness is the thickness of a CdS or other buffer film in a thin film solar cell.

    Abstract: Provided is a method for identifying material junctions and doping characteristics in semiconductor and other materials by illuminating the material and measuring voltage. A correlation between penetration depth of light and wavelength of light is established for a material. Photons are applied to materials such as semiconductor materials to induce charge. The photons are applied by exposing the material to light having a range of wavelengths. The induced charge results in a measureable voltage. The voltage is measured and the voltage measurements used to determine a junction depth and charge concentration of a material using the correlation between penetration depth of light and wavelength of light.
