Current-voltage characteristic raising techniques for solar cells. comparisons and applications

Interpreting the current- voltage I-V characteristic of the solar cells gives important information about functional parameters. The paper presents a comparison between the most important techniques of raising the I-V characteristic for solar cells. The improvement realized for raising the characteristic using a capacitor as a load resistance is also presented. A new method to determine the series resistance is developed using the I-V characteristic, and the comparison with the previously methods is also made.
