Comparison of fluorescent down-shifting layers for increasing the efficiency of CdS/CdTe solar cells
Comparison of fluorescent down-shifting layers for increasing the efficiency of CdS/CdTe solar cells
The poor spectral response of some Cadmium Sulfide/Cadmium Telluride (CdTe/CdS) solar cells in the UV/blue part of the spectrum can be improved through down-shifting of light using fluorescent dyes. A fluorescent down-shifting structure absorbs UV/blue light and emits it at a longer wavelength where the External Quantum Efficiency (EQE) of the solar cell is significantly higher. This study compares fluorescent structures with different dyes and different concentrations, some benefiting from resonance energy transfer. The results indicate that the application of a down-shifting structure is effective in increasing the EQE of the solar cell in the UV/blue light region, and can also be used to concentrate light from a larger area onto the solar cell. A theoretical model is being developed and the first results have been compared with experimental spectroscopic results, with a satisfactory agreement

Abstract
The poor spectral response of some Cadmium Sulfide/Cadmium Telluride (CdTe/CdS) solar cells in the UV/blue part of the spectrum can be improved through down-shifting of light using fluorescent dyes. A fluorescent down-shifting structure absorbs UV/blue light and emits it at a longer wavelength where the External Quantum Efficiency (EQE) of the solar cell is significantly higher. This study compares fluorescent structures with different dyes and different concentrations, some benefiting from resonance energy transfer. The results indicate that the application of a down-shifting structure is effective in increasing the EQE of the solar cell in the UV/blue light region, and can also be used to concentrate light from a larger area onto the solar cell. A theoretical model is being developed and the first results have been compared with experimental spectroscopic results, with a satisfactory agreement
