Perovskite absorber composition engineering patents: mapping who owns the claim space
43.0% concentration. The top 5 of 302 records in scope hold 130 filings between them — a tight cluster at the front of the field. Filings ran from 16 in 2017 to a peak of 52 in 2019, then settled into a steadier band; 2021's 15 filings grew to 22 by 2024, a +47% rise over that span. Counts for 2025 and 2026 are still filling in as publication catches up with filing, so they should not be read as a slowdown.

Common questions about this landscape
Who holds the most patents in perovskite absorber composition engineering?
The dataset ranks 100 companies by patent family, and the leader alone holds 38 of the 302 records in scope. The top five combined hold 130 records, or 43.0% of the total, showing a steep drop-off after the leading few organisations. Beyond the top ten, which together hold 59.6% of records, the field spreads across a long tail of universities and manufacturers with only a handful of filings each.
Is filing activity in this field growing or slowing down?
Filings rose from 15 in 2021 to 22 in 2024, a +47% increase over that three-year span, indicating sustained rather than fading interest. The field's single busiest year remains 2019 at 52 filings. Counts for 2025 and 2026 look lower only because publication typically lags filing by about 18 months, not because activity has actually dropped.
Which patent classes cover perovskite absorber composition claims?
The two largest IPC subclasses are H10K (organic semiconductors, covering 68.2% of the 302 records) and H01L (semiconductor devices, 48.0%). Smaller but notable classes include H01G (capacitors), C07F (organo-metallic compounds) and C30B (crystal growth), each under 13% of records. Because a single record can carry several IPC classes, these shares add up to more than 100%, and each should be read against the 302-record total rather than against each other.
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 Perovskite Absorber Composition Engineering 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.
