Last week, sampling trials of 1200 × 600 mm flexible perovskite modules were successfully carried out for a customer.

Using our in-house pilot line platform a total of 100 flexible perovskite samples were produced and delivered for customer evaluation.This achievement demonstrates the feasibility of large-area flexible perovskite module production at a practical sample volume.

While flexible perovskite technology still faces process-related challenges compared to rigid glass-based modules, these challenges were addressed through our pilot line capabilities and precise process tuning, resulting in successful sampling.

Among the fabricated modules, peak power conversion efficiencies of up to 20% on active area under stabilized conditions were achieved with an average efficiency of 17-18% across the samples.

These efficiency values were measured using in-house measurement tools for internal evaluation purposes.

The samples were manufactured using a sheet-to-sheet production system, demonstrating the potential for stable and controlled manufacturing of large-area flexible perovskite modules.

Although flexible perovskite technology continues to face challenges related to durability and operational lifetime, we will continue working closely with customers and partners as an equipment manufacturer to address these challenges and to contribute to the commercialization of flexible perovskite solar technologies.
