The back contact on top of the CdTe layer.ĬdTe is an ideal absorber material for high-efficiency low cost thin film polycrystalline solar cells. The typical superstrate structure of a CdTe/CdS solar cell is composed of four layers as follows:Ī transparent and conducting oxide (TCO) which acts as a front contactĪ CdS film which is also called window layer Schematics of a typical superstrate CdS/CdTe solar cell structure

The schematics of CdS/CdTe Solar cell is shown in Fig 1.įig 1. Efficiencies as high as 16.5% have been achieved, but still there is some potential for increasing them. The absorber layer thickness for thin film CdTe solar cells is normally between 2 and 10 m. Thin film CdTe solar cells are typically hetero-junctions with CdS being the n-type partner, or window layer. On the other hand, CdS has a bandgap energy of 2.42 eV, and transmits most of the visible spectrum. The two key properties of this material are its band gap (1.5 eV), close to the ideal for photovoltaic conversion efficiency (1.45 eV), and its high optical absorption coefficient. Polycrystalline thin film CdTe continues to be a leading material for the development of cost effective and reliable photovoltaics.

To obtain the highest efficiency, the thickness of CdTe and CdS has been modified separately to check the improvement of cell efficiency in PC1D simulator and efficiency beyond 20% has been achieved.

However, the help file is no longer supported directly by more recent versions of Windows. PC1D works in all windows versions up to Windows 7. Not shown are the extra nodes at the rear of the device.ĭuring simulation it is also possible to pause the program and examine the spatial distribution of carriers or field across the device at a particular bias point. The cell is 300 micrometer thick but only the first few microns are shown to show the extra notes in the emitter and the depletion region. The number of nodes is increased in parts of the cell where the doping is changing and near surfaces.ĭoping density as a function of distance from the front for the model described above. Once the user has setup the basic model PC1D, generates a number of nodes to solve. The user can alter the cell parameters and either use internal models or provide externally measured data.

#PC1D SOLAR CELL SIMULATION CODE#
The raw source code of PC1D is now available on SourceForge for programmers and developers. PC1D is now available free of charge from the University of NSW. It is used to simulate new device performance and also for new users to develop an understanding of device physics. Its success is based on its speed, user interface and continual updates to the latest cell models. PC1D is the most commonly used of the commercially available solar cell modelling programs.
