政策促進因素、技術發展以及在建築物中引入太陽能發電所面臨的挑戰。

建築業是全球脫碳進程中的關鍵領域，促進建築太陽能應用的政策正逐步從獎勵和補貼轉向強制安裝。雖然屋頂太陽能發電仍然是最廣泛採用的解決方案，但將太陽能模組整合到建築立面、窗戶和其他建材中的內置光伏（BIPV）也正在迅速普及。

除了傳統的晶體矽太陽能電池外，鈣鈦礦太陽能電池因其輕薄、半透明、柔軟性等特性以及不斷提高的轉換效率，被認為是建築光伏一體化（BIPV）系統中極具前景的技術。其主要挑戰​​包括如何在發電效率與建築美觀之間取得平衡、如何降低初始安裝成本以及如何滿足現有建築的結構承重和防水要求。

另一方面，建築中太陽能發電的引入也加速了經營模式向綜合服務的轉變，這種綜合服務結合了發電、儲能、電力消耗和併網，為該行業創造了新的機會。

主要亮點

• 建築領域的太陽能政策正在從補貼轉向強制安裝，使其成為全球脫碳的關鍵領域。
• 雖然屋頂太陽能發電仍然是主流，但建築一體化光伏（BIPV）系統（將組件與立面、窗戶和其他建築材料結合）也在迅速發展。
• 鈣鈦礦太陽能電池被認為是一種很有前途的生物誘導光伏（BIPV）技術，因為它們重量輕、半透明、柔軟性，而且轉換效率還在不斷提高。
• 主要挑戰包括平衡發電效率與建築美觀、高昂的初始安裝成本以及現有建築物的結構承重和防水需求。
• 此外，將太陽能發電引入建築物正在推動經營模式向綜合服務方向發展，將發電、儲能、電力消耗和與電網的整合結合起來，為該行業創造了新的機會。

第4章：TRI的觀點

The building sector is a key area for global decarbonization, with policies promoting solar adoption in buildings gradually shifting from incentives and subsidies toward mandatory installation. Rooftop solar remains the most widely adopted solution, while building-integrated photovoltaics (BIPV), which incorporate solar modules into facades, windows, and other building materials, are growing rapidly.

In addition to conventional crystalline silicon, perovskite solar cells are regarded as a promising technology for BIPV due to their lightweight, thin, semi-transparent, and flexible characteristics, as well as continued advances in conversion efficiency. Key challenges include balancing power-generation efficiency with architectural aesthetics, high upfront installation costs, and structural load-bearing and waterproofing requirements for existing buildings.

Meanwhile, solar adoption in buildings is also driving business models toward integrated services combining power generation, energy storage, electricity consumption, and grid interaction-creating new opportunities for the industry.

Key Highlights

• Building-sector solar policy is shifting from subsidies toward mandatory installation, making it a key area for global decarbonization.
• Rooftop solar remains the dominant application, while building-integrated photovoltaics (BIPV, combining modules with facades, windows, and other building materials) is growing rapidly.
• Perovskite solar cells are seen as a promising BIPV technology for their lightweight, semi-transparent, flexible properties and continually improving conversion efficiency.
• Key challenges include balancing power-generation efficiency with architectural aesthetics, high upfront installation costs, and structural load-bearing and waterproofing requirements for existing buildings.
• Building solar adoption is also driving business models toward integrated services combining power generation, energy storage, electricity consumption, and grid interaction-creating new opportunities for the industry.
