在覆盖电池板的玻璃或塑料片上沉积一种电敏透明材料，传感器监测灰尘等级，当灰尘达到额定等级时，系统发生作用，利用电池板所发电流产生一个电荷。

An electrically-sensitive transparent material is deposited on glass or a plastic sheet that covers the panel. Sensors monitor the dust levels.

绝对最大额定值部分(图2)规定了耐压等级，如否，就可能对器件造成永久性的损坏。

The absolute maximum ratings section (Figure 2) specifies the stress levels that, if exceeded, may cause permanent damage to the device.
