Phosphor (Energy Converter)
Inorganic phosphor materials
“Classical” inorganic phosphors usually consist of a host lattice with activator ions doped into it in small concentrations, typically a few mole percent or less.
Host lattice & Activator ion
1st type : weak interaction (Ln3+)
2nd type: strong interaction ( Mn2+, Eu2+, Ce3+, Pb2+,Sb3+, Ce3+, MoO42-, NbO43-)
Activator (+ Sensit
WHAT IS A SOLAR CELL?
Devices that convert solar energy to electric energy.
WHAT IS PHOTO ELECTRIC EFFECT?
The photoelectric effect is a phenomenon in which electrons are emitted from matter as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet light
Absorption and generation of exciton

3) The superiority of Ti plate as the substrate of dye-sensitized solar cells
This figure is light irradiation in DSSC's based on (a) metal substrate(Ti, stainless steel) and (b) FTO substrate. In this paper, nano crystalline TiO2 coated on FTO, Ti and stainless steel substrated was applied as a photoelectrode of DSSCs.
In conclusion, the sheet resistance of metal substrate seems to be const
통한 평가에 이르는 과정을 Team work에 의해 수행하며, 창의성을 강조한 해결방한 도출, 역학 해석과 개념 검증, 기본 설계, 도면 작성 및 Design contest를 위한 간단한 장치의 제작을 목표로 한다.
