| Outline of Annual Research Achievements |
In this fiscal year we will develop a method to spray-coat methylammonium bismuth iodide (MABI) nanocrystals onto heated substrates and integrate them to the single junction prototype solar cell devices. Solar cells will be prepared by combination of spray and coating the colloidal solution of MABI nanocrystals onto a substrate heated on a hotplate at various temperatures. The solar cell stability and performance will be characterized.
We have developed a method to spray-coat MABI nanocrystals onto heated substrates. Devices were prepared by spray coating the colloidal solution of MABI nanocrystals onto a substrate heated on a hotplate at various temperatures. We employed a solar cell structure based on our previous works on perovskite solar cells and the device structure was as follows: Glass/Indium-doped Tin Oxide/Compact TiO2/mesoporous TiO2/MABI nanocrystals/spiro-MeOTAD/Au. The solar cell devices were then characterized using a solar simulator and external quantum efficiency spectrometer. Typical perovskite devices are based on MAPbI3 and similar concoctions, and when these materials degrade they generally form PbI2, which is a wide bandgap insulator. However, the phase change of MABI leads to the formation of BiI3 which has a bandgap of ~1.7 eV and is therefore more favourable for PV applications.
