透明光致发光是一种新技术，可用于建筑应用，同时节省能源和产生电力。本研究评估了美国四个城市：底特律、洛杉矶、凤凰城和檀香山的透明光伏（TPV）在窗户和天窗应用中的潜力。建筑能源需求模拟，光伏发电，生命周期评估（LCA）相结合，以评估净能源效益（NEB）。TPV在窗户上的使用被评估为两种新的窗户，其中太阳能电池被沉积在玻璃窗格的内表面中，以及用于现有窗户的翻新，其中塑料封装的太阳能电池被放置在现有窗户的内表面上。NEB被认为是积极的所有考虑的情况下，和摇篮门能源制造透明的有机光伏模块被认为是微不足道的。利用NEB模型计算了能源投资回报率（EROI）和能源回收期（EPBT）。这两种技术都比其他光伏技术更好或相当。对于玻璃模块，最好的EROI是102在凤凰城的窗口和208在檀香山的天窗。EPBT从51天到1.1年不等，取决于模块的位置和类型。在美国使用透明的光致发光材料被发现具有环境和成本效益，因为它同时减少了建筑物的能源消耗和电力生产。
Transparent photovoltaics is a new technology that can be used in buildings applications to simultaneously save energy and produce electricity. This study evaluates the potential of transparent photovoltaic (TPV) in window and skylight applications for four cities in the United States: Detroit, Los Angeles, Phoenix and Honolulu. Building energy demand simulation, photovoltaic generation, and life cycle assessment (LCA) are combined to evaluate the net energy benefit (NEB). The use of TPV on windows is evaluated for both new windows, for which the solar cell is deposited in the interior surface of the glass pane, and for the refurbishment of existing windows, for which plastic encapsulated solar cells are placed on the interior surface of existing windows. The NEB was found to be positive for all scenarios considered, and the cradle to gate energy to manufacture a transparent organic photovoltaic module was found to be negligible. The NEB was used to calculate the energy return on investment (EROI) and the energy payback time (EPBT). Both were found to be either better or comparable to other photovoltaic technologies. For glass modules, the best EROI was 102 in Phoenix for window and 208 in Honolulu for skylights. The EPBT varied from 51 days to 1.1 years, depending on the location and type of module. The use of transparent photovoltaics in the US was found to have both environmental and cost benefits due to the combined reduction in building energy consumption and electricity production.
