Increasing insights into the operational features of experimental solar cells, particularly the effects of spatial variations arising from material quality fluctuations or device design features, are being made possible by advanced characterisation technologies, such as luminescent imaging.
Unwanted variation due to variable raw material quality is often a problem in production processes.
Of these, 221 were high quality (HQ) and 658 were low quality variations (LQ) as defined by the same algorithm (see materials and methods).
The technique achieves a reduction of variability due to variation in raw material qualities, compared to ordinary robust process optimization.
What are the material qualities of the network?
A neural network model for predicting the quality or soundness of the injected plastic parts based on key process variables and material grade variations has been developed.
With changes in COV which can reflect variation of repair material and quality, repairing cost varies insignificantly and the results from decreasing COV go to those from deterministic method.
With the development of newer materials and variation in the quality of the surface as well as coating, a handy method for the estimation of absorptivity is always useful.
Manufacturers recorded raw materials for quality management.
