Summary

In this project, ANU is working with Monash University to develop new materials and designs for perovskite solar cell electrodes. A limitation of perovskite cells is that so far the highest efficiency cells have used high cost electrodes with limited stability, such as gold. This project will develop novel multi-layer integrated contacts that can achieve high efficiency, low cost, and improved stability. A variety of integrated electrode structures will be developed and tested for efficiency and stability, and the cost of the developed structures will be assessed. The result is expected to be perovskite solar cells with substantially improved stability that have the potential for commercialisation.

(a) Schematic of the multilayer electrode concept. The transparent front electrode assembly consists of a blocking layer (BL), a current collection layer (CCL) and a current transport layer (CTL). The rear electrode consists of a BL and a combined CCL/CTL layer. (b) Photo of a semi-transparent perovskite cell fabricated at ANU, which includes a front electrode assembly consisting of MoOx (BL), ITO (CCL) and a metal grid (CTL). The gridlines can be faintly seen running vertically across the cell.
