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.
当从蓄电池中提取电流时，蓄电池内发生化学作用，使电流流动。
When current is withdrawn from the battery, chemical actions take place to produce the flow of current.
结果表明，大的比表面积能吸附更多染料，对提高电池的电流起了关键性作用。
Results showed that the larger surface area could absorb more dye which was the key factor to improve the current.
