Dear Akram Jassim Jawad may be the following list of Optical Simulator can help you., you can go through and try according to your requirement.

01. Elmer : An Open source multiphysical simulation software developed by Finnish Ministry of Education's CSC, written primarily in Fortran (written in Fortran90, C and C++).

02. Goptical : A C++ optical design and simulation library. Goptical is free software. It provides model classes for optical components, surfaces and materials.

03. OpenRayTrace : Cross platform optical design software.  It uses Python, wxPython,  pyOpenGL and related APIs.

04. Monte Carlo technique : Flexible method for simulating light propagation in tissue.

05. Luxrender to Blender : Light transmission (Absorption & Scattering) can be simulated with open-source renderers.

06. Tolerancer : Setting intelligent tolerances and creating engineering drawings for the lens & Start editing the ISO 10110 lens drawings in Tolerancer.

07. Kratos Multiphysics : Designed as an Open-Source framework for the implementation of numerical methods for the solution of engineering problems. It is written in C++ and is designed to allow collaborative development by large teams of researchers focusing on modularity as well as on performance.

08. COMSOL Multiphysics : A general purpose software platform, based on advanced numerical.

09. Atlas : A 2D and 3D device simulator that performs DC, AC, and transient analysis for silicon, binary, ternary, and quaternary material-based devices. Atlas enables the characterization and optimization of semiconductor devices for a wide range of technologies. Accurately characterizes physics-based devices in 2D or 3D for electrical, optical, and thermal performance without costly split-lot experiments.

10. ASA Software : Can be used to simulate solar cells quickly using the latest academic technology. The software uses an integrated opto-electronical approach, which combines both the optical and electronic domain to translate solar cell materials to electrical solar cell performance. ASA is therefore capable of accurately predicting solar cell performance such as JV curves, Fill Factors and solar cell efficiencies.

11. GenPro4 Software : An optical model for solar cells that combines wave and ray-optics in an computationally efficient way. The model has been validated for a wide range of wafer based and thin-film solar cells.

Thank you Zia Ullah Khan for your reply,

Please, which one is more useful in the simulation of ARC polymer for solar cells?

Regards,

i think COMSOL Multiphysics , Atlas and ASA.

you may also try General Purpose Photovoltaic Device Model (GPVDM) simulation based.
