This material can also be used as anti-reflection layer. The required index of refraction for this layer to act as anti-reflector is 1.9 and SiON has refractive index ranging from 1.8 to 2.0. By applying this encapsulation technique, cell gets a value of 2% reflectivity. The enhanced corrosion resistance may make it more stability and longer lifetime of amorphous silicon solar cell.

Experiment purpose
• Understanding electrochemical test method and principle
• Learning how to evaluate the corrosion characteristics
• Examination the influence of alloy addition on the corrosion
resistance of aluminum for a Al-air Battery.
, discrete second phase, 중간금속화합물, 석출물 형성
Ga, In은 Al보다 particle size가 큼
고용한 초과 시
합금의 second phase는 cathodic 반응 속도 증가
matrix로의 Al 손실 과정을 증가시킴
합금의 morphology와 조성의 국부적 불균질은 부식의 특별한 형태를 발생
ex) intergranular corrosion
exfoliation corrosion
is good one to be PIMs
Operate at very low temperature
High efficiency of a PEM ; 40 to 60 percent
Compact and light units (Small volume)
Solid electrolyte ; easier and cheaper
manufacture and more safety
Less corrosion ; longer cell & stack life
Excellent power density
Small noise
Convenience of installation
High durability
Environmentally friendly
