本研究主要為將高分子分散型液晶(Polymer-dispersed Liquid Crystal , PDLC)薄膜結合太陽能透光模組，開發太陽能可調光隔熱玻璃窗，利用太陽能玻璃的高透光性、紫外線阻隔之特性，結合PDLC薄膜調控電壓達變色效果，將兩者的優勢應用於建築智慧窗戶，不但擁有發電、節能及調光功能，搭配蓄電池、逆變器，使其成為小型獨立型光電系統，並對材料進行光學試驗、熱學試驗，得出各層材料的光熱學性質，再經由軟體模擬出太陽能可調光隔熱玻璃窗的材料性質，開發出第一代太陽能可調光隔熱玻璃窗，以第一代產品為基礎改良後，開發出節能效益更高的第二代太陽能可調光隔熱玻璃窗，再以軟體模擬建物的發電量及耗能量，探討在不同氣候型態的地點，其發電及耗能量之差異，最後對太陽能可調光隔熱玻璃窗做經濟效益及環境效益的評估。
從研究結果可以發現，改良後的第二代太陽能可調光隔熱玻璃窗，對於建物而言，在光學性質的部分，太陽能可調光隔熱玻璃窗能降低日光穿透率、可見光穿透率，有效的調節室內照明，在熱學性質的部分，與第一代產品相比，大幅降低熱傳導係數(U值)與遮蔽係數(SC值)，有效阻隔外界的傳導熱與太陽輻射熱。從軟體模擬結果可知，相較於使用一般玻璃的帷幕大樓，若使用太陽能可調光隔熱玻璃窗做為玻璃帷幕牆，不但達到節能省空調之效益、降低電力需求、減少碳排放量，同時能在PDLC薄膜處於霧面狀態時，可做為大面積的投影屏幕，用來投影大面積商用廣告，使其在夜晚無太陽能發電功能時，亦有其他附加功能使用。本研究開發太陽能可調光隔熱玻璃窗，以試驗和模擬的方式進行隔熱和節能之評估，並且設計出小型獨立型光電系統，無需連接市電，可利用自身太陽能玻璃產生的電能直接使用，且具備有隔熱、遮光功能，還可做為投影布幕使用，在提升建築能源效率及減少碳排放量的同時，也能兼顧室內環境的舒適度與都市美學。

This research focuses on integrating polymer-dispersed liquid crystal (PDLC) thin films with solar transparent modules to develop solar adjustable light and heat-insulated glass windows. By utilizing the high transparency and UV-blocking properties of solar glass, combined with the voltage-regulated color-changing effect of PDLC thin films, the advantages of both technologies are applied to smart windows in buildings. This not only provides power generation, energy efficiency, and dimming functionality but also creates a small standalone photovoltaic system when paired with batteries and inverters. The study involves optical and thermal testing of materials to determine their optical and thermal properties, followed by software simulations to analyze the material properties of solar adjustable light and heat-insulating glass windows, such as thermal conductivity (U-value), shading coefficient (SC-value), and visible light transmittance. The first-generation solar adjustable light and heat-insulating glass windows are developed based on these findings. After further improvements based on the first-generation product, the second-generation solar adjustable light and heat-insulating glass windows with higher energy-saving benefits are developed. Software simulations are used to evaluate the electricity generation and energy consumption of the windows in different climatic conditions. Finally, an assessment of the economic and environmental benefits of the solar adjustable light and heat-insulating glass windows is conducted.
From the research results, it can be observed that the improved second-generation solar adjustable light and heat-insulating glass windows provide several advantages for buildings. In terms of optical properties, these windows can reduce daylight transmittance and visible light transmittance, effectively adjusting indoor lighting. In terms of thermal properties, compared to the first-generation product, the windows significantly reduce the thermal conductivity (U-value) and shading coefficient (SC-value), effectively blocking external conductive heat and solar radiation. From the software simulation results, it is evident that using solar adjustable light and heat-insulating glass windows as curtain walls in glass-clad buildings, instead of conventional glass, not only achieves energy-saving benefits, reduced air conditioning requirements, and decreased power demand, but also allows for large-scale projection screens when the PDLC films are in a frosted state. These screens can be used for projecting large commercial advertisements, providing additional functionality even when solar power generation is not available at night. This study develops solar adjustable light and heat-insulating glass windows, evaluates their thermal insulation and energy-saving performance through experiments and simulations, and designs a small standalone photovoltaic system that operates independently of the grid by utilizing the electricity generated by the solar glass itself. The windows offer insulation and shading functions, enhancing building energy efficiency, reducing carbon emissions, and considering indoor comfort and urban aesthetics.
