This is a limitation within the PC1D source code set by the size of the cache memory at the time the program was written * Corresponding author. It is impossible for users to perform simulations that require both long duration and small time steps. Conversely, if small time steps are desired, only short duration simulations can be achieved.

As a result, if long duration simulations are required, big time steps should be chosen. However, one limitation of PC1D is that the number of time steps in transient excitation mode is limited to 200. It is widely used as a simulation tool for photovoltaic research and industry, not only helping users to understand the fundamental mechanism and operation of solar cells, but also efficiently giving reliable and predictable results for research purposes. Introduction PC1D is a computer program used for modelling crystalline semiconductor devices, with emphasis on photovoltaic devices. Peer-review under responsibility of the scientific committee of the SiliconPV 2014 conference Keywords: PC1D transient time step limit 1. ( Peer-review under responsibility of the scientific committee of the SiliconPV 2014 conference. This is an open access article under the CC BY-NC-ND license 2014 The Authors. The proposed method allows simulations over long times with high time precision, which is currently not possible in PC1D in transient excitation mode The Authors. By comparing the results obtained from PC1D using the proposed method with results obtained from a finite element analysis, the correctness of the method is confirmed. 1 Available online at ScienceDirect Energy Procedia 55 (2014 ) th International Conference on Silicon Photovoltaics, SiliconPV 2014 A method to overcome the time step limitation of PC1D in transient excitation mode Kai Wang* and Ivan Perez-Wurfl School of Photovoltaic and Renewable Energy Engineering, University of New South Wales, Sydney 2052, Australia Abstract This paper presents a method to overcome the time step limitation of PC1D in the transient excitation mode without changing the source code of PC1D.
