In this paper, by developing a mathematical model, the temperature of PSCs under different operating conditions has been calculated. It is found that by reducing the density of tail states at the interfaces through some passivation mechanisms, the operating temperature can be decreased significantly at higher applied voltages. The results show that if the density of tail states at the interfaces is reduced by three orders of magnitude through some passivation mechanisms, then the active layer may not undergo any phase change up to an ambient temperature 300 K and it may not degrade up to 320 K. The calculated heat generation at the interfaces at different applied voltages with and without passivation shows reduced heat generation after reducing the density of tail states at the interfaces. It is expected that this study provides a deeper understanding of the influence of interface passivation on the operating temperature of PSCs.
在本文中，通过建立一个数学模型，计算了不同工作条件下PSC的温度。研究发现，通过一些钝化机制降低界面处的尾态密度，在较高的外加电压下工作温度可显著降低。结果表明，如果通过一些钝化机制将界面处的尾态密度降低三个数量级，那么在环境温度300 K以下，有源层可能不会发生任何相变，在320 K以下也不会降解。在有无钝化的不同外加电压下，计算得到的界面处的发热情况表明，降低界面处的尾态密度后发热减少。预计这项研究能更深入地理解界面钝化对PSC工作温度的影响。
