Thin-Film Solar Cell Current Voltage and Time-Resolved Photoluminescence Simulation Model

NREL has developed a simulation modeling tool to analyze recombination losses in polycrystalline thin-film photovoltaics, including cadmium telluride (CdTe) and copper indium gallium diselenide solar cells.

We acknowledge the U.S. Department of Energy Solar Energy Technologies Office's support for this research. 

Download Simulation Model

The current voltage (JV) and time-resolved photoluminescence (TRPL) simulation model application is available for both Mac and Windows operating systems.

Model Application Installation

A user must have administrative rights during installation, and the installation will include embedded COMSOL Runtime™. After installation, the application can be run from a user account.

Model Implementation

For a description of the physical model and its implementation, see Diverse Simulations of Time-Resolved Photoluminescence in Thin-Film Solar Cells: A SnO2/CdSeyTe1-y Case Study, Journal of Applied Physics (2021).

Model User Interface
