Last week, sampling trials of 1200 × 600 mm flexible perovskite modules were successfully carried out for an International customer.
Using our in-house pilot line platform, a total of 100 flexible perovskite samples were produced and shipped. This achievement demonstrates the feasibility of large-area flexible perovskite module production at a practical volume for customer evaluation.
While flexible perovskite technology still faces process-related challenges compared to rigid glass-based modules, these issues were addressed through our pilot line capabilities and precise process tuning, resulting in successful sampling.

Among the fabricated modules, peak efficiencies of up to 20% were achieved, with an average efficiency of 17–18% across the samples.
The modules were manufactured using a sheet-to-sheet production system, highlighting its potential for stable and controlled manufacturing compared to roll-to-roll processes.
The delivered samples will be used by the customer for performance evaluation and application development toward next-generation lightweight photovoltaic solutions.
As an solution provider, we will continue working closely with customers and partners to address remaining challenges such as durability and lifetime, and to contribute to the commercialization of flexible perovskite solar technologies.
