Over the past decade, metal-halide perovskite solar cells have advanced from a laboratory curiosity to a credible thin-film technology, yet the path from a high-efficiency rigid cell to a manufacturable flexible module remains the field’s central engineering problem. This talk presents a cohesive body of work, comprising twelve publications, that traces the maturation of perovskite photovoltaics from fundamental interface engineering on rigid cells toward flexible, scalable, and multijunction device platforms.
The story begins at the device interface, where high-temperature metal-oxide scaffolds give way to low-temperature, solution-processable charge-selective contacts that decouple efficient charge extraction from the thermal budget and lift planar-cell performance above 17%. These low-temperature interfaces are precisely what makes plastic substrates viable, and the work then moves onto flexible foil, combining alternative electrodes, printed deposition, and interface passivation to bring flexible-cell efficiency toward 18-19% with markedly improved stability. The final thread scales these single cells, demonstrating large-format flexible modules and tandem architectures.
Read together, the twelve papers describe a deliberate progression from fundamental interface physics on rigid cells to scalable, flexible, and multijunction device platforms, and outline the design strategies that connect them.
