With the considerable progress in efficiency, stability and manufacturability, perovskite solar cells are now well along the path to reaching commercialisation. While single junction silicon photovoltaic technology has reached an impressive 26.7 percent power conversion efficiency, it will be forever limited to efficiencies below 30 percent. We will discuss how in a few short years, Oxford PV’s perovskite technology in tandem with silicon has achieved a certified 28 percent efficiency, and the clear roadmap to efficiencies extending well beyond 30 percent. Additionally, this talk will explain the importance of a fundamental understanding of the perovskite material properties and its relationship with the development of a stable technology; sharing long-term reliability test data based on the IEC61215 standards. We will also reflect on the challenges and progress that has been made to scale this perovskite-silicon tandem solar cell technology from the lab to commercial sized solar cells at pilot production and initial manufacturing levels.
