The decent power conversion efficiency (~20%), ultra-low cost, and 1-year stability make carbon-based perovskite solar cells (C-PSCs) one of the most promising candidates for commercialization in the field of perovskite photovoltaics. However, the stability of C-PSCs still lags behind that of the commercialized silicon and thin-film photovoltaics. Although there have been many reviews of the long-term stability of perovskite solar cells (PSCs), none has specifically focused on the long-term stability of C-PSCs. Herein, we summarize the environmental risks and strategies for ensuring the long-term stability of C-PSCs, highlighting also the various contributions of our research group. The most important factors affecting long-term stability are analyzed according to the environmental risks (i.e. moisture, oxygen, light, and thermal stress) of device degradation. The proposed strategies chiefly center around improving the intrinsic stability and strengthening encapsulation. In our conclusions, we also present an outlook on future work concerning stability improvement and commercial development of C-PSCs. Our work provides a clear guideline for future research on C-PSCs.

体面的功率转换效率（〜20％），超低的成本以及1年的稳定性使碳基钙钛矿太阳能电池（C-PSC）成为钙钛矿光伏领域最有前景的商业化候选产品之一。但是，C-PSC的稳定性仍然落后于商业化的硅和薄膜光伏产品。尽管对钙钛矿太阳能电池（PSC）的长期稳定性已有许多评论，但没有人专门关注C-PSC的长期稳定性。在此，我们总结了确保C-PSC长期稳定性的环境风险和策略，并着重强调了我们研究小组的各种贡献。根据环境风险（例如湿气，氧气，光线，和热应力）。提出的策略主要围绕改善固有稳定性和加强封装。在我们的结论中，我们还对有关C-PSC稳定性和商业开发的未来工作提出了展望。我们的工作为未来的C-PSC研究提供了明确的指南。
