发明名称 Transient photoluminescence measurements
摘要 A photoluminescence mapping system and method for use in fabricating solar cells that eliminates the need for complex and expensive light sources, filters and high sensitivity cameras. Generally, the method includes: (i) irradiating a surface of the substrate with radiation having a predetermined energy for a first predetermined period of time to photogenerate carriers therein; (ii) stopping the irradiation; (iii) exposing the surface of the substrate to a camera for a second predetermined period of time; and (iv) capturing with the camera a photoluminescence (PL) signal emitted from the surface of the substrate.
