Optical characteristics of highly efficient silicon photovoltaic cells

Statistical evaluation of the characteristics of damaged solar panels of spacecraft

“…The choice of an equivalent scheme and a set of assumptions for SC description is carried out depending on the problem being solved. A rather complete overview of the problems to be solved and the cell models suitable for their solution is presented in the papers [1][2][3][4][5][6][7][8][9]. To build a model (1) during the study of SC operation under external effects that can lead to the occurrence of damage of various types, the equivalent scheme shown in Fig.…”

“…where I SCload current or SC output current; I phphotocurrent generated by light of minority carriers; I revreverse saturation current; q e = 1.60217653 [5,[7][8][9][10].…”

“…During spacecrafts operation two types of processes of degradation of individual elements of the SB can be observed: a smooth change in the properties of the SC as damages accumulate as a result of the unfavorable factors (UF) action or a stepwise change in the SC properties. The methodological apparatus that allows simulating the process of SB operation with a smooth change in the SC properties is sufficiently developed [1][2][3][4][5][6][7][8][9], however, there are no models that describe the process of SB operation in the case of stepwise change in the SC properties. The list of SC characteristics, causes and examples of their stepwise changes are presented in the paper [10].…”
