Description
Technical Field
The invention belongs to the technical field of optoelectronic materials and devices, and relates to a method for preparing a SnO 2 electron transport layer film by taking stannous oxalate as a raw material.
Background
The perovskite solar cell has the characteristics of low cost and high efficiency. Currently, the authentication efficiency of perovskite solar cells has reached 25.5%, which can be compared with commercial crystalline silicon solar cells, and the perovskite solar cells have great commercial application potential. Perovskite solar cells are typically composed of an electron transport layer, a perovskite layer, a hole transport layer, and an electrode, wherein the electrode comprises a transparent conductive electrode and a metal electrode.
For perovskite solar cells of positive type structure, the most commonly used electron transport layers typically include TiO 2,SnO2 and ZnO. Compared with TiO 2 and ZnO, the SnO 2 material has higher electron mobility, higher optical transmittance, more suitable energy band position and excellent chemical stability, so that the SnO 2 electron transport layer is more and more important. The raw material for preparing the SnO 2 electron transport layer is typically SnCl 2、SnCl4、SnCl2·2H2O、SnCl4·5H2 O and commercial SnO 2 nanoparticle solutions. The SnO 2 electron transport layer (publication No. CN 104157788A) can be prepared by using the sol formed by the hydrolysis of SnCl 2·2H2 O, but the hydrolysis process has poor controllability and is easy to be influenced by external environment. SnCl 2·2H2 O is dissolved in absolute ethyl alcohol, snO 2 nano particles can be obtained after heating reflux and long-time aging, and the highest photoelectric conversion efficiency of the perovskite battery based on the SnO 2 electron transport layer prepared by the method can reach 19.20％(Qingshun Dong,Yantao Shi,Chunyang Zhang,Yukun Wu,Liduo Wang,Energetically favored formation of SnO2 nanocrystals as electron transfer layer in perovskite solar cells with high efficiency exceeding 19％,Nano Energy,2017)., but the method is complex to operate and takes longer time. The commercial SnO 2 nano particles are used as an electron transport layer, and the perovskite solar cell (Qi Jiang,Zema Chu,Pengyang Wang,Xiaolei Yang,Heng Liu,Ye Wang,Zhigang Yin,Jinliang Wu,Xingwang Zhang,Jingbi You,Advanced Materials,2017). with high efficiency and high stability can be prepared, but the commercial SnO 2 nano particle solution has higher cost and unknown chemical composition, and is not beneficial to further optimizing the performance of the perovskite solar cell. In conclusion, the research on the SnO 2 electron transport layer which is low in cost, simple to operate and controllable in chemical composition has important significance for further reducing the manufacturing cost of the perovskite battery and improving the photoelectric conversion efficiency of the perovskite battery.
