“…They recommended the linear viscoelastic material model as a material model for analysing the behavior of encapsulant in solar cells after comparing three different material models. Ding et al [7] investigated the effect of pre-soldering and soldering voltages on the interfaces of interconnecting tabs connected to the interconnect.…”

The differences in the configuration and thermal expansion coefficient of solar cell modules result in thermal stress when solar cells undergo high and low-temperature cycles in orbit, which induces the failure of battery module connections. In this paper, finite element modeling and simulation methods are used to study the thermal compatibility design of four different layers of rigid carbon fiber mesh panels: [0/90]3s, [0/90-45/-45-0/90], [0/90-45-45/-45], and [45/-45]3s. The results show that the substrate configuration with a larger proportion of 0/90 layers has good thermal adaptability for the interconnect-oriented battery array.

“…The III-V compound solar cells represented by GaAs solar cells have attracted great attention in research community because of their high-efficiency potential, possibility of thinfilms, good temperature coefficient, radiation-resistance, and potential of multi-junction application [1][2][3][4][5]. The development of multi-junction solar cells has broken the limiting efficiency of single-junction solar cells.…”

Reducing the surface optical loss and broadening the spectral response range is an effective method to improve the power conversion efficiency of the multi-junction solar cells. We simulated the different HLHL (high/low/high/low index) antireflection coatings (ARCs) for the triple-junction solar cells based on an optical transfer matrix. From the ARC optimization results, the total effective reflectivity (R e ) of ZnS/MgF 2 /ZnS/MgF 2 is the lowest among HLHL ARCs, which is 1.34%, best R e at the region of interest appeared to be 5.03% for the top solar cell, 1.20% for the middle solar cell, and 0.93% for the bottom solar cell. Moreover, the effects of thickness, refractive index, and incident angle on the performance of the ZnS/MgF 2 /ZnS/MgF 2 ARC were analyzed. It was found that the thickness of each film decreases when it deviates from the optimal theoretical value, and the appropriate reduction of MgF 2 refractive index can reduce total R e . The ZnS/MgF 2 /ZnS/MgF 2 ARC exhibits remarkable antireflection properties over a broad wavelength and a wide angular range. The experimental results showed that the reflectance spectrum of ZnS/MgF 2 /ZnS/MgF 2 is basically consistent with the theoretical curve.
