OPTICAL PROPERTIES OF CdTe/CdS SOLAR CELLS DETERMINED BY INFRARED FOURIER TRANSFORMER (FTIR) SPECTROSCOPY
Journal Title: Journal of Science And Arts - Year 2011, Vol 16, Issue 3
Abstract
CdS/CdTe solar cells have attracted much attention as the most suitable candidate for thin-film compound solar cells, and research is being conducted to establish the viability of these devices. Although the films are polycrystalline of just a few microns, the record efficiency of 16.7% has been obtained [1-2]. The achievement of higher voltages has been raised as a topic for future research, but it is thought that higher efficiency can be achieved by understanding the optical properties of CdS/CdTe interface and this is crucial for improving the multilayer CdS/CdTe device performance. In the present study, we have used the Infrared Fourier Transformer (FTIR) spectroscopy to determine the optical indexes n and k. These real and imaginary parts of visible and infrared refractive indexes of our multilayer system are determined by the Kramers-Kronig (KK) transformation of the reflectance spectra thanks to FTIR spectroscopy. It is expected that these cells will be an important semiconductor product and contribute to meeting the energy needs of the future.
