Solar cells in superstrate arrangement need a protective cover glass as one of its main components. The effectiveness of these cells is determined by the cover glass's low weight, radiation resistance, optical clarity, and structural integrity. Damage to the cell covers brought on by exposure to UV irradiation and energetic radiation is thought to be the root cause of the ongoing issue of a reduction in the amount of electricity that can be generated by solar panels installed on spacecraft. Lead-free glasses made of xBiO-(40 - x)CaO-60PO (x = 5, 10, 15, 20, 25, and 30 mol%) were created using the usual approach of melting at a high temperature. The amorphous nature of the glass samples was confirmed using X-ray diffraction. At energies of 81, 238, 356, 662, 911, 1173, 1332, and 2614 keV, the impact of various chemical compositions on gamma shielding in a phospho-bismuth glass structure was measured. The evaluation of gamma shielding revealed that the results of the mass attenuation coefficient of glasses increase as the BiO content increases but decrease as the photon energy increases. As a result of the study conducted on the radiation-deflecting properties of ternary glass, a lead-free low-melting phosphate glass that exhibited outstanding overall performance was developed, and the optimal composition of a glass sample was identified. The 60PO-30BiO-10CaO glass combination is a viable option for use in radiation shielding that does not include lead.
覆层结构的太阳能电池需要一块保护盖板玻璃作为其主要组件之一。这些电池的效能取决于盖板玻璃的低重量、抗辐射性、光学清晰度和结构完整性。暴露于紫外线辐射和高能辐射下导致电池盖板受损，被认为是安装在航天器上的太阳能电池板发电量持续减少这一问题的根本原因。采用常规的高温熔融方法制备了xBiO-(40 - x)CaO-60PO（x = 5、10、15、20、25和30摩尔%）的无铅玻璃。使用X射线衍射确认了玻璃样品的非晶态性质。在81、238、356、662、911、1173、1332和2614 keV的能量下，测量了各种化学成分对磷铋玻璃结构中γ射线屏蔽的影响。γ射线屏蔽评估表明，玻璃的质量衰减系数结果随着BiO含量的增加而增加，但随着光子能量的增加而降低。通过对三元玻璃的辐射偏转特性进行研究，开发出了一种整体性能优异的无铅低熔点磷酸盐玻璃，并确定了玻璃样品的最佳成分。60PO-30BiO-10CaO玻璃组合是用于无铅辐射屏蔽的一个可行选择。
