When translating photovoltaic technology from laboratory to commercial products, low cost, high power conversion efficiency, and high stability (long lifetime) are the three key metrics to consider in addition to other factors, such as low toxicity, low energy payback time, etc. As one of the most promising photovoltaic materials with high efficiency, today organic–inorganic metal halide perovskites draw tremendous attention from fundamental research, but their practical relevance still remains unclear owing to the notorious short device operation time. In this comment, we discuss the stability issue of perovskite photovoltaics and call for standardized protocols for device characterizations that could possibly match the silicon industrial standards.

解决钙钛矿型太阳能电池在商业应用中的稳定性问题

将光伏技术从实验室转化为商业产品时，低成本，高功率转换效率和高稳定性（长寿命）是除低毒，低能源回收时间等其他因素之外还需要考虑的三个关键指标。作为一种最有前途的高效光伏材料，当今有机-无机金属卤化物钙钛矿受到基础研究的极大关注，但由于众所周知的装置运行时间短，它们的实际相关性仍然不清楚。在这篇评论中，我们讨论了钙钛矿光伏技术的稳定性问题，并呼吁针对器件表征的标准化协议可能与硅工业标准相匹配。
