Despite the great success of organic photovoltaics in terms of device efficiency and stability at the laboratory scale, pressing demand for high-throughput and cost-effective solutions remains unresolved and rarely reported. Here we propose that a sequential-deposition, blade-coating approach using donor and acceptor materials can facilitate high-speed fabrication of photoactive layers while maintaining device performance. The sequential-deposition-processed blend and thickness of its designed PM6:T8 system can be optimized by the fine-tuning of the solution concentrations and coating speeds. We show that this strategy can be applied to a non-halogenated solvent and under high-humidity conditions. This high-speed approach is applicable to other non-fullerene photovoltaic systems and the slot-die coating technique. Techno-economic analysis suggests that this strategy can decrease the minimum sustainable price of module manufacturing. Overall, this work represents a step towards the scalable, cost-effective manufacturing of organic photovoltaics with both high performance and high throughput.
