PERC Solar Cell Module Patents: Leaders & White Space 2026
PERC solar cell module manufacturing patents: who holds the interconnection claims
24 families total, a small, still-forming corpus rather than a saturated field — most of the claim space remains open. Filings rose from nothing in 2017 to a peak of six in 2018, dropped to zero by the 2022 midpoint, and are now rebuilding — a pattern more consistent with a niche filing around a specific manufacturing technique than a mainstream, continuously-filed category.

Common questions about PERC module manufacturing patents
How many patent families cover PERC solar cell module manufacturing?
This landscape identifies 24 published patent families that combine PERC or passivated-emitter-rear-contact terminology with module-assembly steps such as cell stringing, interconnection and lamination. That is a small corpus compared with PERC cell chemistry generally, because it isolates the specific seam between cell architecture and module assembly. The number will grow as filings from the last 18 months complete publication, since publication lags filing by roughly that long.
Who are the leading filers in PERC module interconnection technology?
No single assignee dominates this corpus; filing activity is spread across a small number of entities including TP Solar Ltd, which is the only assignee with a recorded filing in the latest tracked year. Several other tracked assignees, including Avalon Solar Tech Pty Ltd, show no filings in the most recent year after being active earlier. The field currently favours whoever files next over any single incumbent with sustained volume.
Why did PERC module manufacturing filings peak in 2018 and then drop?
Filing activity in this dataset rose to a peak of six records in 2018, then fell away entirely by the 2022 midpoint before showing a small resumption toward 2026. That pattern is consistent with a specific technical problem — likely early cell-to-module interconnection loss — being addressed by a cluster of filers around 2017-2019, after which interest cooled until newer manufacturing issues, such as bifacial or shingled designs, prompted fresh filings.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on PERC Solar Cell Module Manufacturing covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
