Perovskite solar cells (PSCs) are promising candidates for the next generation of solar cells because they are easy to fabricate and have high power conversion efficiencies. However, there has been no detailed analysis of the cost of PSC modules. We selected two representative examples of PSCs and performed a cost analysis of their productions: one was a moderate-efficiency module produced from cheap materials, and the other was a high-efficiency module produced from expensive materials. The costs of both modules were found to be lower than those of other photovoltaic technologies. We used the calculated module costs to estimate the levelized cost of electricity (LCOE) of PSCs. The LCOE was calculated to be 3.5-4.9 US cents/kWh with an efficiency and lifetime of greater than 12% and 15 years respectively, below the cost of traditional energy sources.
钙钛矿太阳能电池（PSC）因其易于制造且具有高功率转换效率，成为下一代太阳能电池的有力候选者。然而，目前尚未对PSC组件的成本进行详细分析。我们选择了两个具有代表性的PSC示例，并对其生产成本进行了分析：一个是由廉价材料制成的中等效率组件，另一个是由昂贵材料制成的高效组件。结果发现，这两种组件的成本均低于其他光伏技术。我们利用计算得出的组件成本来估算PSC的平准化度电成本（LCOE）。当效率大于12%且寿命大于15年时，计算得出的LCOE为3.5 - 4.9美分/千瓦时，低于传统能源的成本。
