Since Snaith’s first report of solid-state perovskite solar cells [1], device efficiencies have increased to 21% [2]. To date, such devices have been manufactured using processes which are also difficult to scale due to physical limitations and toxicity issues [3].
It is known that the structural, physical and electronic parameters of perovskite devices are closely related to the method of fabrication which means that device performance may not be reproducible when moving from one manufacturing technique to another. This is crucial for up-scaling this technology towards commercial manufacturing.
Here, we will present our recent studies of novel perovskite processing approaches which either avoid the use of toxic solvents [4] or which use self-assembly to control the nature of the deposited perovskite. We will discuss the implications of these data for scaled manufacturing.
Interestingly, our data also suggest enhanced material and device lifetimes for these new processing approaches [4] and we will present these findings and consider the reasons behind them.
