**6.7 General-purpose photovoltaic device model (Gpvdm)**

GPVDM is a free and versatile simulating software for optoelectronic devices and was created by Roderick C. I. Mackenzie at Imperial College London. This tool was written for simulation of PV solar cells but later on it is proficient to simulate the working of multiple classes of devices such as OFETs, OLEDs, optical filters, first, second and third generation PV solar cells. Until now, this tool can simulate a lot of devices as mentioned below.


This simulating software has both electrical and optical modules for producing and analyzing the precise solar cell simulations for various applications with respect to requirements [25]. This platform assists an easy and operational tool to explore the effect of optoelectronic properties. **Figure 6** visualizes the graphical user interface in GPVDM.
