    摘要: Methods (600) and systems (100) for inspecting an indirect bandgap semiconductor structure (140) are described. A light source (110) generates light (612) suitable for inducing photoluminescence in the indirect bandgap semiconductor structure (140). A short-pass filter unit (114) reduces long-wavelength light of the generated light above a specified emission peak. A collimator (112) collimates (616) the light. A large area of the indirect bandgap semiconductor structure (140) is substantially uniformly and simultaneously illuminated (618) with the collimated, short-pass filtered light. An image capture device (130) captures (620) images of photoluminescence simultaneously induced by the substantially uniform, simultaneous illumination incident across the large area of the indirect bandgap semiconductor structure. The photoluminescence images are imaged processed (622) to quantify spatially resolved specified electronic properties of the indirect bandgap semiconductor structure (140) using the spatial variation of the photoluminescence induced in the large area.

    摘要: Embodiments of methods and systems for identifying or determining spatially resolved properties in indirect bandgap semiconductor devices such as solar cells are described. In one embodiment, spatially resolved properties of an indirect bandgap semiconductor device are determined by externally exciting the indirect bandgap semiconductor device to cause the indirect bandgap semiconductor device to emit luminescence (110), capturing images of luminescence emitted from the indirect bandgap semiconductor device in response to the external excitation (120), and determining spatially resolved properties of the indirect bandgap semiconductor device based on a comparison of relative intensities of regions in one or more of the luminescence images (130).
