双面光伏（BPV）是一项快速发展的技术，可以通过利用电池板两侧的光照射来提高发电量。 BPV 垂直东西向安装提供了两个生产高峰，一个在早上，一个在晚上，而不是在中午有一个突出的高峰。 BPV 的垂直安装使其与典型负载曲线更加匹配，并提高了家庭和邻里系统 BPV 生产的自消耗。提高小型光伏系统的自耗至关重要，因为它可以提高经济效益并降低电网互动的要求。在高纬度地区，垂直 BPV 特别有益，因为平均太阳高度角较低，使得垂直表面能够在数小时内有效收集辐射。本综述基于建模和实验角度以及将光伏与不同级别的电网集成来研究当前最先进的 BPV。讨论了 BPV 在电力生产中的适用性、其与建筑环境和景观的融合以及在高纬度条件下阻碍其实施的障碍。 BPV 具有潜力，近年来其应用显着增长。然而，许多关键问题未能解决诸如垂直安装 BPV 在平准化电力成本方面的定量经济效益等领域。
Bifacial photovoltaics (BPV) is a rapidly growing technology that can improve electricity production by utilizing light irradiation from both sides of the panel. A vertical east-west mounting of BPV provides two production peaks, one in the morning and one in the evening, instead of one prominent peak at noon. The vertical mounting of BPV leads to a closer match with typical load profiles and improves the self-consumption of BPV production for household and neighborhood systems. Improving the self-consumption of small-scale PV systems is vital because it increases economic profitability and reduces the requirements for grid interaction. At high latitudes, vertical BPV can be especially beneficial, as the low average solar altitude angle enables the vertical surfaces to efficiently collect irradiation for many hours. This review investigates current state-of-the-art BPV based on modelling and experimental perspectives as well as integrating PV with power grids at different levels. The suitability of BPV in electricity production, its integration to the built environment and landscape and the barriers impeding its implementation are discussed for high latitude conditions. BPV has potential and its application has grown significantly over recent years. However, many key questions have failed to address areas such as the quantitative economic benefits of vertically mounted BPV in terms of the levelized cost of electricity.
