To observe carbon nanotube electrode morphology in perovskite solar cells
実験 / Experimental
TEM was adopted to observe the morphology of bare carbon nanotubes and PTAA-CNTs mixture. PTAA is a kind of polymer applied as the hole transport layer material in solar cell research.
結果と考察 / Results and Discussion
Carbon nanotubes synthesized by the chemical vapor deposition method were utilized as novel electrodes in perovskite solar cells to replace traditional high-cost gold electrodes. We mixed the hole transport layer (HTL) materials and CNTs by a spin coating method. The mixed HTL-CNTs layer functioned as both holes transporting facilitator and the top electrode at the same time, achieving a comparable power conversion efficiency as previously used gold electrodes. In the experiment, we discovered that PTAA, a kind of polymer applied as hole transport layer material, displayed an extraordinary physical combination with carbon nanotubes electrode, forming a dense and compact layer, which greatly enhanced the device stability towards humidity. By further TEM characterization, we successfully observed PTAA polymer wrapping around carbon nanotubes on the nanometer scale, which firmly proved our previous hypothesis.
