Comparison of outdoor and indoor PL and EL images in Si solar cells and panels for defect detection and classification Terrados López, Cristian González Francés, Diego González Fernandez, Diego Alonso Gómez, Víctor González Rebollo, Miguel Ángel Jiménez López, Juan Ignacio Martínez Sacristán, Óscar Luminescence techniques are very powerful techniques for the detection and classification of defects in solar cells and panels. Daylight EL technique is quite useful for offering safe inspection of solar plants on-site, with clear advantages respect to night EL (providing the same information, although with lower resolution). Daylight PL does not need for a power source, although it still needs for electrical contacts. The information provided is mainly related to C cracks or B/C cracks. PL with an external source gives also useful information of the defects present in a solar cell, also cracks can be visualized. However, it is complicated to be performed on-site. 2023-05-19T09:02:27Z 2023-05-19T09:02:27Z 2023-05-19T09:02:27Z 2022 info:eu-repo/semantics/conferenceObject 19th International Conference on Defects-Recognition, Imaging and Physics in Semiconductors (DRIP19), 29/08 – 01/09 2022, Japan (on-line) https://uvadoc.uva.es/handle/10324/59647 eng https://confit.atlas.jp/guide/event/drip19/top info:eu-repo/semantics/openAccess
