PC-1D version 2: enhanced numerical solar cell modelling

PC-1D is a finite-element program for modeling semiconductor devices in one dimension on personal computers. It has the ability to address complex issues associated with heavy doping, high-level injection, and transients. Significant improvements have been made to the program, resulting in a new version. The authors describe the enhancements and their application to modern crystalline cells, including new provisions for heterostructures, antireflection coatings and light trapping, an upgraded user interface, and unattended operation for optimization studies.
