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.
尽管功率转换是光伏窗的一个重要指标，但它必须与可见光透射率、美学效果（颜色和雾度）以及热性能相平衡。光学性能经常被报道，但在光伏窗设计中，热性能通常完全被忽视。在此，我们介绍了使用层压层来改善基于钙钛矿的光伏隔热玻璃组件热光性能的策略。我们通过将传输矩阵法光学模型与一维热传递模型相结合来设计层压材料和隔热玻璃组件。我们通过在玻璃上沉积并层压到钙钛矿光伏器件上的一维光子晶体层的实验制备来验证我们的模型。整体设计消除了固有的透射红色，“红色低辐射率”设计显著降低了玻璃表面的发射率，从而显著提高了隔热性能并提升了器件的光电流。
