New Application in Version 5.2a Si Solar Cell with Ray Optics This app combines the Ray Optics Module and the Semiconductor Module to illustrate the operation of a silicon solar cell at a location specified by the user. The Ray Optics Module computes the average illumination over a day of the year and a location chosen by the user. The Semiconductor Module computes the normalized output characteristics of a solar cell with design parameters specified by the user. The normalized output characteristics are then multiplied by the computed average illumination to obtain the output characteristics of the cell at the specified date and location, assuming a simple linear relationship between the output and the illumination.
