Solar Panel Structures Efficiency Is Of Great Significance
Xiamen Sunforson Power Co.,Ltd | Updated: Oct 17, 2017

The growing shortage of fossil fuels on earth and their environmental problems have prompted researchers to turn their eyes to clean renewable energy. Solar energy as a clean and safe, Solar panel structures resource-rich new energy has long been a widespread concern, its use and conversion technology has been changing rapidly. Especially in recent years, the development of the most rapid solar cell in the field of perovskite solar cells, after less than 10 years of development time its device efficiency has rapidly exceeded 22%, Solar panel structures is considered to be the future of the most potential for industrial applications of solar cell technology. Therefore, it is of great significance to study how to improve the photoelectric conversion efficiency of perovskite solar cells.

The factors that affect solar cell efficiency can be divided into two kinds: electrical loss and optical loss. The loss of electricity mainly comes from the composite loss in the process of optical carrier transport, which depends on the properties of the material and the structure design of the device. Solar panel structures Optical loss is mainly due to the loss of optical trapping efficiency caused by surface reflection, occlusion loss and spectral response characteristics of the battery material itself. At present, new perovskite materials and new device structures have been developed continuously, especially from the angle of reducing electrical loss to provide many new ideas for improving the photoelectric conversion efficiency of perovskite solar cells. At the same time, Solar panel structures it is an important problem to improve the performance of perovskite solar cell and reduce optical loss.

The optical scattering phenomenon induced by nanostructure and the surface plasmon resonance effect stimulated by the nanometer-scale structured metal back electrode can enhance the efficiency of photoelectric conversion by synergistic effect. Compared to conventional planar devices, Solar panel structures the optical circuit of the perovskite solar cell with one-dimensional grating and the structure of the moth-eye is significantly improved, and the existence of the nanostructure has no obvious effect on the open-circuit voltage and filling factor, so the photoelectric conversion efficiency of the device is improved by 8.3% and 14.3% respectively. Solar panel structures The team compared the periodic grating structure and the quasi-periodic moth-eye structure to the mechanism of photoelectric conversion of the device, combined with the optical simulation, further validated and expounded the influence of nanometer structure on the light regulation of the perovskite solar cell devices and the unique advantages of the structure of the moth-eye.
