碩士 === 南台科技大學 === 機械工程系 === 94 === We present our results about the encapsulation technique of solar cells for solar cars. In order to fully make use of the efficiency of space used solar cells, we chose a special material – Dupont Tefzel. Thus, the encapsulation parameters have to be investigated anew. Therefore we compared the transmittens between PC and Tefzel films. Tefzel was used as surface cover to encapsulate several cells as test samples. Then, we measured their efficiency variation under high temperature and high humidity to study the influences of temperature and humidity on encapsulation. Experiments results showed that in contrast to PC films, Tefzel has higher transmittens in UV area and thus is suitable for encapsulating multi-juntion solar cells. However, its shrink coefficience is also higher than that of PC films so that its manufacture process, usage and maintance are also different from those of PC films. Our primary results showed that the best curing conditions were achieved under 155°C and 6 minutes.
