Recently, metal halide perovskite photovoltaics (PV) are marching toward commercialization. The possibility for perovskite absorbers to be incorporated into multi-junction solar cells is also being discussed, which suggests alternative market entry. Although intensive investigations are being made on their technical feasibility, serious analysis on the cost of perovskite-based tandem modules is lacking. The levelized cost of electricity (LCOE) of solar modules is often used to evaluate technoeconomic competitiveness. Here, we performed a detailed cost analysis on two perovskite-based tandem modules (the perovskite/c-silicon and the perovskite/perovskite tandem module) compared with standard multi-crystalline silicon and single-junction perovskite solar cells. We found that perovskite PVs (both single junction and multi-junction) are competitive in the context of LCOE if the module lifetime is comparable with that of c-silicon solar cells. This encourages further efforts to push perovskite tandem modules onto the market in the future.

近来，金属卤化物钙钛矿光伏（PV）正在迈向商业化。也正在讨论将钙钛矿吸收剂结合到多结太阳能电池中的可能性，这表明了替代市场的进入。尽管正在对其技术可行性进行深入研究，但缺乏对钙钛矿基串联模块成本的认真分析。太阳能电池组件的平均电费（LCOE）通常用于评估技术经济竞争力。在这里，我们对两种基于钙钛矿的串联模块（钙钛矿/硅和钙钛矿/钙钛矿串联模块）与标准多晶硅和单结钙钛矿太阳能电池进行了详细的成本分析。我们发现，如果模块寿命可与c硅太阳能电池相媲美，则钙钛矿PV（单结和多结）在LCOE方面具有竞争力。这鼓励了进一步的努力，以便将来将钙钛矿串联模块推向市场。
