Program Description
PC1D is a computer program written for IBM-compatible personal computers which solves the fully coupled nonlinear equations for the quasi-one-dimensional transport of electrons and holes in crystalline semiconductor devices, with emphasis on photovoltaic devices. This version of the program is supported and distributed by the Photovoltaics Special Research Centre at the University of New South Wales in Sydney, Australia 2052. Only licensed copies of the program are authorized for use. A licensed copy may be loaded and used on multiple computers or on a network provided the licensee maintains records of the number and location of these authorized copies and can ensure that all notifications and updates are distributed to everyone using these copies. Licensed copies are available from the PV Centre for a fee of AUST$150, which may be paid by credit card or by cheque. Contact the PV Centre via e-mail at pc1d@unsw.edu.au to receive an order form via fax.
PC1D runs under Windows 95/98/ME/XP/NT, and requires at least an 80386 CPU and an 80387 math coprocessor (note that most 80486 and Pentium processors have the math coprocessor built-in). It will also run on Windows 3.1 if Win32s is installed (Win32s 1.71 or later is required).
Only one file is necessary to run the program, PC1D.EXE. The additional file PC1D.HLP provides on-screen help, and several additional files are provided which contain material parameters for selected semiconductors, standardized solar spectra, and example problems. All of the files can be simply copied into the directory of choice; no setup program is required. To store files of different type in different directories, see the instructions for the Options menu.
PC1D will continue to be improved and your suggestions are appreciated. Submit them via e-mail at the address shown above. Of particular interest are any computation errors that may arise, and improved values for material parameters as they become available. Licensed users will receive update notices. Those who register an e-mail contact address will be provided with maintenance updates of the program and its associated files via e-mail at no cost.
