Do you have any background knowledge about instrumentation physics ? İf you have ı can explain to you. Regards

Thank you for replay very much Prof. Abdulkadir Kavasoglu.

I live in Gaza -Palestine .We have no setup to record IV table.

I can buy buy (low coast) Data Aquestion card But I don't Know what is the exact one.

also we have external circuit to get points of IV curve. we have small software also

Prof. Abdulkadir Kavasoglu. Sorry i don't know exactly what do yo means(instrumentation physics )

thanks very much

I think Keithley is more expensive solution. You need a one computer controlled voltage source ( digital to analog convertor with amplifier output) and logartitmic current to voltage convertor (to measure current in a super wide range) and last items is at leeast two channel voltage data loger (two channel analog to digital convertor with having high resolution )

What is the bits required for adc and have to give me details

thanks

Selâmün aleyküm Hussan nice to see you again.

I should say that you are going to need at least 12 bit resolution ADC and 12 bits DAC with suitable connector.

Dear Hussam,

i may come later to your question. As your question is a basic one and we already developed a complete i-v measuring set up based on the DAQ cards, please refer to the paper in the link: Conference Paper Experimental Performance Characterization of Photovoltaic Mo...

For the software you can ask the first author of the paper.
