A Study of the Structure Optimization of Silicon-Based Solar Cells

Abstract:

Two methods of realizing the Quantum Cutting of Sunlight wave by modulating the sunlight-frequency are introduced in this essay. Based on Lu₂O₃, The low-conversion powder composed of Tb³⁺and Yb³⁺is prepared by co-precipitation method; Using NaYF₄ as a foundation, the up-conversion powder containing Er、Yb and Tm is prepared by hot water extraction. Experiments show that, a high-energy photon in the powder of Lu₂O₃,Tb³⁺and Yb³⁺ can be cut into two 974nm near-infrared photons. The co-doped material up-conversion can have a significant effect on the up-conversion when using the 1122nm laser light to irradiate the 0.25cm² experiment silicon photovoltaic cells, and the photocurrent density of battery can be increased to 0.06mA/cm². In this paper, the PTN silicon structure with nanostructural characteristics is designed for a method to increase the photovoltaic effect. The analysis of results indicates that the effects of the external electric field on the photovoltaic voltage and photocurrent are important.
