考虑到环境保护，“绿色”材料被越来越多地用于光伏发电。在此，我们开发了一种基于氮掺杂碳点的量子点太阳能电池。采用柠檬酸和氨气直接热解法制备了氮掺杂碳点。氮掺杂碳点的激子吸收取决于碳点中n掺杂的含量。n掺杂可以很容易地通过反应物的质量比进行修饰。构建的“绿色”氮掺杂碳点太阳能电池在AM 1.5 G一次全太阳光照下的最佳功率转换效率为0.79%，是碳点太阳能电池的最高效率。本文的在线版本（doi:10.1186/s11671-016-1231-1）包含补充材料，可供授权用户使用。
Considering the environment protection, “green” materials are increasingly explored for photovoltaics. Here, we developed a kind of quantum dots solar cell based on nitrogen-doped carbon dots. The nitrogen-doped carbon dots were prepared by direct pyrolysis of citric acid and ammonia. The nitrogen-doped carbon dots’ excitonic absorption depends on the N-doping content in the carbon dots. The N-doping can be readily modified by the mass ratio of reactants. The constructed “green” nitrogen-doped carbon dots solar cell achieves the best power conversion efficiency of 0.79 % under AM 1.5 G one full sun illumination, which is the highest efficiency for carbon dot-based solar cells.
