1. Cork Boards are durable, and you’ll hardly see pinholes even after many uses.

2. A position or sun sensor comprises asensor housing, a plurality of pinholes formed in the sensor housing, a detectormounted within the housing and a method of processing the information detected.

3. The tyre pinhole detector and the detection method have high detection accuracy, can accurately find the positions of the existing pinholes and have no danger for the operators.

4. In addition, the formation of amorphous materials or pinholes in the blocking layer can be prevented, thereby improving efficiency, and enabling a large-area dye-sensitized solar cell to be formed.
