Solar cells micro crack detection technique using state-of-the-art electroluminescence imaging

Journal of Science: Advanced Materials and Devices, 2019
In this article, we present the development of a novel technique that is used to enhance the detection of micro cracks in solar cells. Initially, the output image of a conventional electroluminescence (EL) system is determined and reprocessed using the ...

Configurational forces in a micro‐cracked body [PDF]

PAMM, 2007
AbstractA framework to model micro‐cracked bodies based on the theory of continua with microstructure is presented: assuming a crack embedded in each material element, a field is considered characterising size and orientation of the crack, in addition to the usual placement in the Euclidian space.

Effective properties of magnetoelectroelastic interfaces weakened by micro-cracks

, 2018
The effective properties of a microscopically damaged interface between two dissimilar magnetoelectroelastic materials are investigated using a micro‐statistical model. The interface is modeled as damaged by a periodic array of micro‐cracks.

An Investigation of Thermal Effects on Micro-Properties of Sudbury Norite by CT Scanning and Image Processing Method

Mining, 2022
Rock is constantly subjected to stress and thermal conditions. Thermal-induced micro-cracks will be generated as a result of different thermal expansion gradations between different minerals. This characteristic was investigated in this paper by studying
