Though power conversion is an important metric for photovoltaic windows, it must be balanced with visible transmittance, aesthetics (color and haze), and thermal performance. Optical properties are often reported, but thermal performance is typically neglected entirely in photovoltaic window design. Here, we introduce the strategy of using laminate layers to improve the thermo-optical performance of perovskite-based photovoltaic insulating glass units. We design the laminates and insulating glass units by coupling a transfer matrix method optical model to a 1D heat transfer model. We validate our models with experimental fabrication of one-dimensional photonic crystal layers that are deposited on glass and laminated to the perovskite photovoltaic device. The holistic designs neutralize the inherent transmissive red color, and the “red low-e” design dramatically reduce emissivity of the glass surface to significantly improve thermal insulation and boost the photocurrent of the device.

卤化物钙钛矿光伏窗口层压层的整体热光学设计


尽管功率转换是光伏窗口的重要指标，但它必须与可见光透射率、美观性（颜色和雾度）和热性能相平衡。光学特性经常被报道，但在光伏窗口设计中，热性能通常被完全忽视。在这里，我们介绍了使用层压层来提高钙钛矿基光伏中空玻璃单元的热光学性能的策略。我们通过将传递矩阵法光学模型耦合到 1D 传热模型来设计层压板和中空玻璃单元。我们通过实验制造一维光子晶体层来验证我们的模型，这些光子晶体层沉积在玻璃上并层压到钙钛矿光伏器件上。整体设计中和了固有的透射红色，而“红色 LOW-E”设计大大降低了玻璃表面的发射率，从而显着改善了隔热性并提高了器件的光电流。
