이온축적층(221)은 이온을 축적하는 층으로서 공지된 이온저장소재 또는 산화/환원 착색소재가 적용될 수 있고 일 예로서 산화티타늄으로 형성될 수 있다.The ion storage layer 221 may be formed of a known ion storage material or an oxidation / reduction coloring material as a layer for accumulating ions, and may be formed of, for example, titanium oxide.
이온전도층(223)은 통상 양이온 전도성 고체 또는 액체 전해질이 적용된다.The ion conductive layer 223 is generally applied to a cationic conductive solid or liquid electrolyte.
전기변색층(225)은 공지된 다양한 소재 예를 들면, 국내 공개 특허 2003-0067226호에 개시된 무기 전기변색 물질 예를 들면 WO3, NiOxHy, Nb2 O5, TiO2, MoO3 등과, 유기전기변색물질 예를 들면 폴리아닐린(polyaniline) 등 다양하게 알려져 있고 적절한 소재를 적용하면 된다.The electrochromic layer 225 may be formed of various known materials, for example, inorganic electrochromic materials disclosed in Korean Patent Application Publication No. 2003-0067226, for example, WO 3 , NiO x H y , Nb 2 O 5 , TiO 2 , MoO 3, and the like. In addition, organic electrochromic materials such as polyaniline may be variously known and appropriate materials may be applied.
제1전극층(211)과 제2전극층(227)은 도선을 통해 전기적으로 접속되어 있어 태양전지패널에서 생성된 전력을 전기변색패널로 인가한다.The first electrode layer 211 and the second electrode layer 227 are electrically connected to each other through a conductive wire to apply power generated from the solar cell panel to the electrochromic panel.
p형클래드층(219)과 제2전극층(227)은 저항(R)을 통해 전기적으로 접속되어 있다. 저항(R)은 방전용으로 전기변색패널의 응답속도를 향상시킨다. The p-type cladding layer 219 and the second electrode layer 227 are electrically connected through the resistor R. The resistor R improves the response speed of the electrochromic panel for discharge.
이러한 구조의 스마트 윈도우 장치(210)는 입사된 광에 의해 n형클래드층(215)과 p형 클래드층(219) 사이의 공핍층(217)에서 전자-정공 쌍이 발생되고, 발생된 전자-전공이 이동하여 전기적 에너지가 생성된다. 생성된 전기적 에너지는 제1전극층(213)과, 제2전극층(227)에 각각 인가되어 그 사이에 전계가 형성되고, 그에 따라 전기변색패널에 해당하는 이온축적층(221) 내지 전기변색층(225) 사이에서 산화 환원반응이 일어나 전기변색층(225)이 변색된다. 따라서, 광의 입사량이 떨어지면 제1전극층(213)과 제2전극층(227) 사이에 형성되는 전계 또는 구동전류가 낮아져 전기변색층(225)의 광투과도가 높아지고, 광의 입사량이 증가하면 반대로 전기변색패널의 구동전류가 높아져 전기변색층(225)의 광투과도가 떨어진다. 따라서, 광입사도에 역비례하여 광투과도가 결정되기 때문에 여름 및 낮에는 투광량이 줄어들고, 겨울 및 아침에는 투광량이 증가된다.The smart window device 210 having such a structure generates an electron-hole pair in the depletion layer 217 between the n-type cladding layer 215 and the p-type cladding layer 219 by incident light, and generates the generated electron-electron. This shift causes the generation of electrical energy. The generated electrical energy is applied to the first electrode layer 213 and the second electrode layer 227, respectively, to form an electric field therebetween, and thus, the ion storage layer 221 to the electrochromic layer corresponding to the electrochromic panel ( The redox reaction occurs between the 225 and the electrochromic layer 225 is discolored. Therefore, when the incident amount of light falls, the electric field or driving current formed between the first electrode layer 213 and the second electrode layer 227 is lowered to increase the light transmittance of the electrochromic layer 225, and conversely, when the incident amount of light increases, the electrochromic panel is reversed. As the driving current increases, the light transmittance of the electrochromic layer 225 is lowered. Therefore, since light transmittance is determined in inverse proportion to light incidence, the light emission amount decreases in summer and day, and the light emission amount increases in winter and morning.
