Solar Photovoltaic Cell Parameters Extraction Using Differential Evolution Algorithm

open access: yesProceedings, 2020
This work presents a method for extracting parameters from photovoltaic (PV) solar cells, based on the three critical points of the current-voltage (I-V) characteristic, i.e., the short-circuit current, the open circuit voltage and the maximum power ...

Mechanical Parameter Extraction Using Resonant Structures [PDF]

open access: yesMRS Proceedings, 1993
ABSTRACTIn order to model and design micromechanical sensors and actuators, it is of crucial importance that thin film mechanical parameters, such as the Young's modulus and the residual stress, are known. In this paper, the parameter extraction method using resonant structures has been used to obtain these data and has been compared with the bulge ...

Optimization of crystal extraction experiment [PDF]

open access: yes, 1996
Using a computer model for the crystal extraction, we investigate the bent-crystal parameters optimal for the extraction experiment. The optimal crystal curvature is found to be near 1 GeV/cm (for pv/R), i.e.
