The role of low light intensity: A step towards understanding the connection between light, optic/lens and photovoltaic behavior for Sb2S3 thin-film solar cells
We report here an optic/lens system that we used so far, for cooling the surface of solar cells, the reduction of light intensity and the change of light distribution that reaches the surface of the solar cell. The objective was to improve photovoltaic characteristics under very low light illumination, as well as to understand the connection between light, optic/lens and photovoltaic behavior for Sb2S3 thin-film solar cells. Et was found that for all so far designed thin-film solar cells made and based on the synthesized Sb2S3, optics/lens system causes an Increase in open circuit voltage (V-oc) and short circuit current (I-sc) and thus the efficiencies of made solar devices. Values of energy gaps for the thin-films made devices were in the range from 1.4 to 2 eV. Improvements of the photovoltaic response of the designed devices are found to be better at the lower light intensity (S% sun), than at higher intensities of light. For the same intensity of light used optic/lens improves the... efficiency of the devices, by changing the light distribution. Other processes that are related to the optics/lens system, leading to an increase in I-sc and V-oc and consequently to an increase in efficiencies of the designed devices, are investigated.
