1) PESC [Passivated Emitter Solar Cell]
light absorption surface
– Inverted pyramids structure, double
reflection prevention layer
front – oxide passivation, electrode
passivation by narrow elctrode area
rear – Al deposition, form p+ layer
electrode
open circuit voltage - below 670 mV
structures of TFT that follow the method delivering the voltage information through the TFT elements of each pixel when appling the voltage are divided into Bottom gate structure including etch stopper stagger type , Back channel etched stagger type and Top gate structure including Coplanar type, Stagger type.
2. Amorphous Silicon은 보통 staggered TFT가 사용되는데 그 이유는 a-Si:H
The optical microscope, often referred to as the "light microscope", is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although there are many complex designs w

주가지수선물거래는 현물상품(즉 주가지수)이 무형자산이어서 매도가 불가능하기 때문에 반대매매에 의한 차액현금 결제에 의해 정산된다. 이러한 선물거래는 크게 헷지 거래(hedge trading)와 투기 거래(speculation trading)로 구분된다. 헷지거래는 현물상품의 선물시장을 통해 현물시장의 가격변
