Abstract

A BIPV-powered smart window comprising a building-integrated photovoltaic (BIPV) panel and an all-solid-state electrochromic (EC) stack is proposed. In the proposed device, the output voltage of the BIPV panel varies in accordance with the intensity of the incident light and is modulated in such a way as to generate the EC stack voltage required to maintain the indoor illuminance within a specified range. Two different EC stacks are fabricated and characterized, namely one stack comprising ITO/WO(3)/Ta(2)O(5)/ITO and one stack comprising ITO/WO(3)/lithium-polymer electrolyte/ITO. It is shown that of the two stacks, the ITO/WO(3)/lithium-polymer electrolyte/ITO stack has a larger absorptance (i.e., approximately 99% at a driving voltage of 3.5 V). The experimental results show that the smart window incorporating an ITO/WO(3)/lithium-polymer electrolyte/ITO stack with an electrolyte thickness of 1.0 μm provides an indoor illuminance range of 750-1,500 Lux under typical summertime conditions in Taiwan.

摘要

提出了一种由光伏建筑一体化（BIPV）组件和全固态电致变色（EC）堆叠组成的 BIPV 智能窗。在提出的装置中，BIPV 组件的输出电压随入射光强度而变化，并进行调制，以产生维持室内照度在指定范围内所需的 EC 堆叠电压。制备并表征了两种不同的 EC 堆叠，即一个包含 ITO/WO(3)/Ta(2)O(5)/ITO 的堆叠和一个包含 ITO/WO(3)/锂聚合物电解质/ITO 的堆叠。结果表明，在这两个堆叠中，ITO/WO(3)/锂聚合物电解质/ITO 堆叠具有更大的吸收率（即在 3.5 V 的驱动电压下约为 99%）。实验结果表明，在台湾典型的夏季条件下，采用厚度为 1.0 μm 的电解质的 ITO/WO(3)/锂聚合物电解质/ITO 堆叠的智能窗可提供 750-1500 Lux 的室内照度范围。
