The CdTe thin film solar cells with the structure of ITO/ZnO/CdS/CdTe/Au were irradiated by 1.6MeV high-energy electrons with the fluences from 5×1013/cm2 to 1×1016/cm2. The characteristics of devices before and after irradiation were studied using dark current-voltage (I-V), capacitance-voltage (C-V) and admittance spectroscopy (AS) measurements in the temperature range from 303K to 353K. The results are shown that the diode ideal factor and dark saturation current for irradiated devices first decrease and then increase significantly with fluences from 5×1013/cm2 to 1×1016/cm2, meantime the effective carrier concentration at room temperature of CdTe absorbing layer increases first and then decreases. The carrier transport mechanisms in CdTe solar cells are analyzed before and after irradiation. The non-irradiated devices and irradiated devices with fluences less than 5×1014/cm2 are dominated by the recombination current of electron-hole pairs in the depletion layer. However, it is dominated by the recombination current of tunneling at the interface after the irradiation of higher fluences. The changes of types and amount of defects caused by electron irradiation are the major reasons for the above mentioned variations.

Czts Thin Films

CZTS thin film, a potential candidate for application as absorber layer in thin film solar cells, has drawn much attention in these years due to its excellent photoelectric performance and nontoxic components. It provides a brief description of the development of CZTS thin film for solar cells, and surveys several methods of depositing CZTS films, then introduces the crystal structure of CZTS which is a problem for composition ratio affecting the properties of CZTS thin films. Here we also outline the development and the structure of solar cells based on CZTS thin films.

ABSTRACTThe focus of this work is on back contact improvement for sputtered CZTS thin film solar cells. Three methods have been investigated including a thin Ag coating, a thin ZnO coating on the Mo back contact and rapid thermal annealing of the back contact. All of these methods have been found to reduce defects such as voids as well as secondary phases at the back contact region and inhibit the formation of MoS2. Consequently all the mothods effectively enhances Voc, Jsc, FF and therefore efficiency significantly.
