You can measure the PIV using IV curve tracer there you will get Voc, Isc, Vmp & Imp. And it can convert that on to STC. You can also convert the Same measured value by using temperature correction factor in the Module Datasheet .  It is simple to do. no need of any research paper.

I thought about something like an introduction to that topic..

As an introduction I may recommend this thesis.
