Organic photovoltaics have emerged as a promising renewable energy technology that can reduce the cost of solar cell production using solution-based processing methods as compared to silicon-based solar cells which require energy intensive manufacturing. Owing to their lightweight, flexibility and transparency, OSCs can also be used in a variety of novel applications including smart windows and powering portable devices or internet of things (IoTs). Although the device performance of OSCs have now reached a promising 19% efficiency in a single junction cell at a laboratory scale, the processing method for most high performance materials has been limited to spin coating, which is incompatible with large area production of OSCs. On the other hand, meniscus-guided coating techniques are not only compatible with large-scale roll to roll manufacturing, but can minimize solution waste to as low as 5%. However, OSCs fabricated by these large-scale compatible processes often lead to poor device performances with inferior film morphologies as compared to spin coated devices likely due to the different drying dynamics and transport processes involved. Currently, controlling the morphology of OSCs for large-scale processing remains a bottleneck, typically requiring time-consuming trial-and-error based approaches to adjust numerous processing parameters for device optimization. Moreover, even a small change in the processing parameters or environmental conditions affect the BHJ morphology, further complicating the device optimization of OSCs. Therefore, achieving favorable morphologies that are processing resilient or less affected by variations in processing parameters and environmental conditions is crucial for successful commercialization of organic photovoltaics.
