双端串联钙钛矿(PK)电池由于其电能转换效率的快速提高，被认为是未来光伏市场的一个有前途的选择。然而，它们的大规模采用需要对这些PV的能量性能有更好的了解。本文对以铜铟镓硒、铜锌锡硒和单晶硅为底电池的铅基PK顶电池组成的双端串联太阳电池的生命周期能耗进行了评估。能量回收期(EPBT)和能量投资回报率(EROI)是检验光伏系统发电性能的两个重要指标。目前最先进的设备的EPBT从7个月到12个月不等，而电池的EROI与EPBT的顺序相反，在5.2到9.2之间。随着串联光伏技术的成熟，串联器件的这两个能源指标有望改善，高效长寿命器件的EBPT低至接近27天(0.9个月)，EROI高达105。
Two-terminal tandem perovskite (PK) cells are considered a promising option for future photovoltaic (PV) market due to the rapid improvements in their power conversion efficiencies. However, their large-scale adoption requires a better understanding on the energy performance of these PVs. In this paper, the life-cycle energy consumptions of two-terminal tandem solar cells consisting of lead-based PK top cells prepared on bottom cells of copper indium gallium selenide, copper zinc tin selenide, and monocrystalline silicon are evaluated. The energy payback time (EPBT) and the energy return on invested (EROI) are the two use-fulmetrics for examining the energy generation performance of PV systems. EPBTs of the current state-of-the-art devices range from 7 months to 12 months, while the EROI of the cells is in the reverse order as the EPBT and ranged between 5.2 and 9.2. These two energy indicators of tandem devices are expected to improve as the tandem PV technologies mature, with an EBPT as low as similar to 27 day (0.9 month) and the EROI as high as 105 for high-efficiency long-lifetime devices.
