A study on the development of deterioration / performance evaluation method for outdoor electric insulation of polymer materials is pushed forward now in the International Council on Large Electric Systems (CIGRE). The small scale docimasy (Dynamic Drop Test) which could evaluate a disappearance characteristic of the hydrophobicity easily was suggested [1] . This test method is to evaluate the loss of hydrophobicity to drop electrically-charged water droplets on the sample surface continuously. We applied this dynamic drop test (DDT) to polymer materials which differ in the amount of Alumina Tri-Hydrate (ATH) filled and investigated factors about the change of hydrophobicity, in which the surface roughness and difference of the quantity of migration of the low molecular weight (LMW) were examined.

We proposed a low-cost plasma process technique to fabricate narrower front electrode grooves on a single crystalline silicon solar cell, in which the surface discharge operated at high-pressure etched the silicon nitride film of 150 nm thickness on a silicon layer. The results showed that the surface discharge could effectively etch the silicon nitride film in a short time and that a high etching rate more than 3000 nm/min was obtained. The narrow and uniform grooves with the width of less than 70 μm were obtained when the pressure in a chamber, the back electrode length and the etching time were 152 kPa, 2 mm and 10 s, respectively. The narrower electrode groove could be obtained when the back electrode length was short and the pressure was high.
