Noise-based analysis of the reliability of silicon solar cells

Abstract

With silicon solar cells as the research object, this paper takes their nondestructive character and analyzes their quality with noise-based technology. Through the stress aging of samples and the testing of various types of noise, including 1/f noise, microplasma noise, and G-R noise, in the cells in the laboratory, the noise characteristics are analyzed. The research results show that noise is correlated with defects in silicon solar cells. The different types of noise can be used to characterize different parts and types of defects in the cells according to the mechanism of generation of noise and the failure physics of photovoltaic devices, and thereby, the evaluation of the quality and analysis of the reliability of solar cells can be achieved.

Nitrogen-Related Defects in Crystalline Silicon

“…Si has been a dominant material in the semiconductor industry for over six decades. It has a wide range of applications in electronic, microelecronic, and optoelectronic fields and especially for nanoelectronic, nuclear medicine, and sensor and photovoltaic devices [1][2][3][4][5]. Typically, Si-based devices are fabricated on single-crystal Czochralski Si wafers.…”

Carbon-Isovalent Dopant Pairs in Silicon: A Density Functional Theory Study

“…Silicon (Si) is the key semiconductor for integrated circuits, transistors, sensors, detectors, solar cells, as well as for applications related to nuclear medicine, space industry, telecommunications, and quantum computing [1][2][3][4][5]. An important issue in the performance of the devices is the presence of defects which affect their electrical, optical, and mechanical properties [6][7][8][9].…”

“…using frequency filtration or/and Fourier transform as in [53,55,58]). However, especially in the case of reliability assessment of mechanical objects it is a very important issue because different noise parameters can be very good diagnostic information carriers [5,25,38,54]. Therefore one can expect that a proper noise assessment is a crucial aspect in the aviation management.…”
