Building-integrated photovoltaics (Figure 1) are finding increasing use in the construction of new buildings as either a primary or auxiliary source of electrical power. In the present study, a BIPV module is integrated with an EC stack in order to realize a BIPV-powered smart window. In the proposed device, the variable output voltage from the BIPV module is used to drive the EC stack and is modulated in such a way as to achieve the specified indoor illumination conditions. Two EC stacks are considered, namely one stack with an ITO/WO3 Ta2O5 ITO structure and a second stack with an ITO/WO3 lithium-polymer electrolyte ITO structure. An experimental investigation is performed to confirm the ability of the ITO/WO3/lithium-polymer electrolyte ITO structure smart window to maintain appropriate indoor illumination conditions over the course of a typical sunny day in Taiwan. |
