Voc of an organic solar cell is related to the difference of LUMO (acceptor) and HOMO(donor). Is there any way like this to model the Jsc of an organic solar cell? I am attaching an image for your reference how to model Voc.
Short circuit current is a bit complicated to model as there are lot of factors that go into defining this. There is lot of work done by Paul Blom on this aspect. Here are couple of papers which can get you started. You are advised to read more from Paul Blom.

All the best :)
The short circuit current is directly related to the number of photons absorbed. So if you are trying to predict Jsc, you need to do some optical modelling, and calculate the total photons absorbed by the active layer. The method to do so is well established (transfer matrix method), or very easily implemented with finite elements as well. So as an initial prediction you can calculate the number of photons absorbed by the active layer and calculate the Jsc, then you can improve this further by considering the recombination processes happening in the active layer.
Hi! You cannot predict the short circuit current directly as right Waranatha L Abeygunasekara claims. It is firstly affected from the selection of the donor (polymer) material and its absorbance (absorbed photons), as well as its crystallinity (films morphology and thermal annealing treatment). Moreover it can be affected by the acceptor material (electron affinity, HOMO level to avoid exciton recombination) etc.
There are some Photovoltaics Analysis Platforms which can be useful for you, as below:
