介绍了一种新型的硼硅酸盐覆盖玻璃材料CMG，它的热膨胀系数在-180℃到+520℃的温度范围内与GaAs相匹配。该玻璃还具有优良的光学透过率、辐射稳定性、低太阳吸收率和高发射率等标准遮盖玻璃特性。通过在砷化镓电池上使用CMG遮盖玻璃，可以生产出更先进、更轻的太阳能电池组件。由于玻璃是膨胀匹配的，它显著降低了电池组件中因热循环而产生的任何应力。它还允许实施先进的粘合技术，如静电粘合，或者使用特氟龙或刚性粘合层。对于砷化镓电池来说，消除盖层玻璃粘合剂将是非常重要的，因为这将是实现超薄的依赖盖层玻璃强度的砷化镓电池的第一步。
A new borosilicate-type coverglass material, CMG, with a thermal expansion coefficient matched to GaAs over a temperature range in excess of -180 degrees C to +520 degrees C is described. The glass also has the standard coverglass properties of excellent optical transmission, radiation stability, low solar absorptance, and high emissivity. By using CMG coverglasses on GaAs cells, a more advanced and lighter solar cell assembly can be produced. Because the glass is expansion-matched, it significantly reduces any stresses within the cell assembly caused by thermal cycling. It also allows advanced bonding techniques such as electrostatic bonding to be implemented or, alternatively, the use of Teflon or a rigid adhesive layer. For GaAs cells the elimination of the coverglass adhesive would be very significant since it would be the first step towards the realization of ultrathin GaAs cells relying on the coverglass for strength.<<ETX>>
