I am a graduate student in university of pittsburgh. I am doing some research about the inorganic solar cells. The source meter I am using right now is a CHI 618b potentiostat (http://www.chinstruments.com/chi600.html). Recently, my solar cells suffered from a low-efficiency problem. I am suspecting that this is probably caused by the I-V measuring ability of this potentiostat, and I noticed that related publications almost exclusively used keithley's products to do similar test, but I need to some solid evidence to convince my boss to buy this 2400 series instrument. Can you please specify the advantages of the 2400 series instrument on solar cell testing, compared to the potentiostat i am using now? thanks a lot.
You say you are measuring Solar cells and need some more reason for your boss to purchase a 2400? There is a company named Green Mountain Engineering who produces a free piece of software for testing Solar Cells. Their software uses our 2400 and 2600 Series SMUs and will save you a lot of time from having to code up something yourself. I have tried the software out myself and it's well done. An excellent value at the price of $0! I recommend you check them out at the link below.
