Description
본 발명은 형광물질이 함유된 염료 감응형 태양전지 및 그 제조방법에 관한 것이다.The present invention relates to a dye-sensitized solar cell containing a fluorescent material and a method of manufacturing the same.
염료 감응형 태양전지는 높은 변환 효율과 저비용으로 제조 할 수 있는 새로운 타입의 태양전지이다. 일반적으로, 염료 감응형 태양전지는 염료의 태양광 흡수 능력을 이용하여 화학적으로 발전을 일으키는 태양전지의 일종으로서, 투명한 유리기판에 금속산화물과 염료가 포함된 광전극, 전해질, 그리고 상대전극 등으로 구성되어 있다.Dye-sensitized solar cells are a new type of solar cell that can be manufactured at high conversion efficiency and low cost. In general, a dye-sensitized solar cell is a type of solar cell that generates chemical power by using the dye's solar absorption ability. Consists of.
다공질 막의 형태로 존재하는 광 전극은 TiO2, ZnO, SnO2와 같은 넓은 밴드갭을 가진 n형 전이금속산화물 반도체로 구성되고, 이 표면에 단 분자 층의 염료가 흡착되어 있다. 태양광이 태양 전지에 입사되면 염료 속의 페르미 에너지 부근의 전자가 태양에너지를 흡수하여 전자가 채워지지 않은 상위 준위로 여기된다. 이때, 전자가 빠져나간 하위 준위의 빈자리는 전해질 속의 이온이 전자를 제공함으로써 다시 채워진다. 염료에 전자를 제공한 이온은 광전극으로 이동하여 전자를 제공받게 된다. 이때, 광전극은 전해질 속에 있는 이온의 산화환원 반응의 촉매로 작용하여 표면에서의 산화 환원 반응을 통하여 전해질 속의 이온에 전자를 제공하는 역할을 한다.The photoelectrode in the form of a porous membrane is composed of an n-type transition metal oxide semiconductor having a wide bandgap such as TiO 2 , ZnO, SnO 2, and a single molecule layer of dye is adsorbed on this surface. When sunlight enters the solar cell, electrons near the Fermi energy in the dye absorb the solar energy and are excited to higher levels where the electrons are not filled. At this time, the vacancy in the lower level where the electrons escape is filled again by the ions in the electrolyte providing the electrons. Ions that provide electrons to the dye move to the photoelectrode to receive electrons. At this time, the photoelectrode acts as a catalyst for the redox reaction of the ions in the electrolyte and serves to provide electrons to the ions in the electrolyte through a redox reaction on the surface.
