最近的材料进步使研究人员能够设想和开发高效，部分透明的光伏（PV）原型，暴露了一个潜在的巨大的和未开发的太阳能市场：建筑集成（BI）太阳能窗户。从这个角度来看，我们评估了BIPV窗户的市场部署情况，特别是针对美国商业高层建筑。太阳能窗户的研究和开发一直基于这样一种假设，即太阳光-电能转换效率（PCE）和单位面积的设备成本是可能推动市场采用的关键因素。在这里，我们通过识别和评估商业高层建筑窗户市场的客户需求来调查太阳能窗户的市场前景和需求。在评估过程中，我们与商业窗户价值链上的专家进行了150次访谈。我们发现，BIPV窗户的最终用户和建设项目的关键决策者之间的激励措施不一致，使市场力量变得复杂。我们的评估使我们能够为BIPV窗户制定新的价值指标，以满足潜在客户的潜在需求以及能源生产的技术指标。最后，我们讨论了一个可能的方向，BIPV窗口技术，其中photopolics与可切换窗口集成。在这里，集成光伏将可见光和红外光传输转换为可用电力，从而实现独立的自供电主动窗户，可以潜在地满足市场对智能窗户的需求，从而为BIPV窗户部署提供途径。
Recent materials advances have enabled researchers to envision and develop highly efficient, partially transparent photovoltaic (PV) prototypes, exposing a potentially large and untapped market for solar energy: building integrated (BI) solar powered windows. In this perspective, we assess the case for market deployment of BIPV windows, specifically intended for commercial U.S. high-rise buildings. Research and development on solar powered windows has been predicated on the hypothesis that sunlight-to-electrical power conversion efficiency (PCE) and device cost per unit area are the key figures of merit that might drive market adoption. Here we investigate the market landscape and desirability for solar powered windows by identifying and evaluating the customer needs for the commercial high-rise building window market. In the course of this assessment, we performed 150 interviews with experts across the value chain for commercial windows. We found that the market forces are complicated by a misalignment of incentives between the end users of BIPV windows and the key decision makers for building projects that could incorporate this technology. Our assessment leads us to frame new figures of merit for BIPV windows that address the underlying needs of prospective customers as well as technical metrics for energy generation. We finally discuss one possible direction for BIPV window technology in which photovoltaics are integrated with switchable windows. Here, the integrated PV converts visible and infrared light transmission into useable electricity enabling standalone, self-powered active windows that can potentially address market needs for smart windows, thereby enabling a pathway for BIPV window deployment.
