The Impurity-to-Efficiency (I2E) simulation tool predicts the impact of as-grown iron impurities and processing conditions on crystalline silicon (c-Si) solar cell performance. The tool enables the optimization of the time temperature profile of phosphorus diffusion gettering. The simulator consists of three primary components:
The simulator uses a Java applet for the user interface and a server for calculations. The server is maintained by the MIT Photovoltaic Research Laboratory in Cambridge, MA. All input and output files over one day old are automatically deleted daily. The server permanently logs IP addresses of users along with the time of simulation, the number of simulations, if the run was successful, and the execution time. The applet is digitally signed to allow the user to save and load files from their local machine. Accepting the signed applet is required to use the PC1D tool and plotting functions. However, it is not required to use the kinetic simulator and lifetime calculator. The applet was constructed with Java 6. Safari is the preferred web browser with Macintosh operating systems. Detailed instructions can be found in the User Manual. Select the Use I2E button below to access the tool.
