In article number 1903085, Woo‐Lim Jeong, Kyung‐Pil Kim, Dong‐Seon Lee, and co‐workers analyze the effects of Na doping on polycrystalline flexible CZTSSe solar cells. When doping is excessive, a device shows low contact potential difference and fill factor and selects a worse carrier transport path even though the built‐in potential becomes stronger. On the other hand, the optimized CZTSSe solar cell clearly showed the enhancing effect of Na doping.

柔性太阳能电池：Na掺杂对多晶柔性Cu2ZnSn（S，Se）4太阳能电池载流子传输路径的影响（Adv。Sci。21/2020）

在Woo-Lim Jeong，Kyung-Pil Kim，Dong-Seon Lee及其同事的文章编号1903085中，分析了Na掺杂对多晶柔性CZTSSe太阳能电池的影响。掺杂过多时，即使内置电势变强，器件的接触电势差和填充因子也较低，并且选择了较差的载流子传输路径。另一方面，优化的CZTSSe太阳能电池清楚地显示出Na掺杂的增强作用。
