All-inorganic solid-state electrochromic device
The invention relates to an all-inorganic solid-state electrochromic device, and belongs to the field of functional thin film devices. Comprising a substrate layer, a first electrode layer, an electrochromic layer and a second electrode layer from bottom to top, the electrochromic layer is composed of a first color changing layer and a second color changing layer; the material of the first color changing layer is one of cation-doped tungsten oxide or cation-doped titanium oxide; the material of the second color changing layer is one of samarium nickelate or lithium cobalt oxide or lithium nickelate; when solar radiation with the wavelength ranging from 300 nm to 1500 nm is used as a light source, the integral transmittance of the all-inorganic solid-state electrochromic device in the high transmittance state ranges from 44.35% to 68.39%, and the integral transmittance of the all-inorganic solid-state electrochromic device in the low transmittance state ranges from 2.18% to 9.73%. According to the invention, an external electric field is utilized to control the complementary anisotropic optical property change before and after metal cations or hydrogen ions enter and exit the metal oxide thin film and the nickelate and cobaltate thin film materials, so that a traditional electrolyte layer structure is structurally canceled, and the upper limit of device performance caused by the existence of an electrolyte layer is effectively improved.
本发明涉及一种全无机固态电致变色器件，属于功能性薄膜器件领域。包括由下至上的基底层、第一电极层、电致变色层和第二电极层；电致变色层由第一变色层和第二变色层组成；第一变色层的材料为掺杂阳离子的氧化钨或掺杂阳离子的氧化钛中的一种；第二变色层的材料为镍酸钐或钴酸锂或镍酸锂中的一种；以波长300～1500nm的太阳辐射为光源时，所述全无机固态电致变色器件在高透射率态的积分透射率为44.35～68.39%，在低透射率态的积分透射率为2.18～9.73%。本发明利用了外加电场控制金属阳离子或者氢离子出入金属氧化物薄膜和镍酸盐、钴酸盐薄膜材料前后的互补异性光学性质变化，从而在结构上取消了传统的电解质层结构，有效提升了电解质层存在导致的器件性能上限。
