I need help in measuring the stability of perovskite solar cells at mppt using ossila source meter.
When I try to use ossila free software, the stabilized current output at mppt doesn't go beyond 999 minutes whereas stability tests could go up to 4-5 days? or shall I measure with solar lifetime measurement tab shown in attached picture.
Your help in this matter will be highly appreciated!
Dear Muhammad Awais ,
I think you have to study your automatic measuring system to use it efficiently.
As for the timing of the measurement, if the maximum programmable time is 999 min. then you can configure the system to restart a new period a number of times as you need for the total observation time. You may need an external timer to issue the required number of the 999 min.
Or you can program it on 12 hours basis of 720 min. If you want to run the test for 5 days for example then you need to restart the measuring timer 9 times and so on.
There may be other solutions but this is a simple solution that may be implemented even manually since the timing of such type of measurements is not very critical.
Best wishes

Muhammad Awais,
I agree and recommend Prof Abdelhalim abdelnaby Zekry logical solution to your question. Since the Osilla instrument is programmable, it's logical to program (set) it to repeat fresh measurement of the parameters after a suitable period so as to take care of your desired measurement duration.

The following link will transport you to a new ResearchGate discussion thread question which is similar to, yet rather different from, this one. In case you might be interested, you are invited to try to provide an answer or a reply! Thanks!
