ABSTRACT
This chapter discusses the utilization of a three-layer system for flat and grooved surface space use solar cells, especially when the idea is to improve the Antireflection coatings (AR) performance in the ultraviolet region without degrading its performance in the visible and infrared regions. The development of an analytical method to calculate AR for solar cells is an important step in solar cell design. The design of AR consists in calculating and minimizing the reflectivity as a function of the wavelength in the range of interest. The Mathematical approach has been used to calculate the deposition parameters for antireflection coatings in optoelectronic devices, such as solar cells and photodetectors. A classical problem for photovoltaic devices is the design of antireflection coatings for silicon solar cells passivated with a Silicon dioxide layer. But it is clear that, with convenient passivation methods, texturization is a powerful tool for improving the carrier collection and simultaneously simplifying the optical coating deposition process.
