Perovskite Module Interconnection Patent Landscape 2026
The perovskite module interconnection space is in active growth, with filings rising sharply on a multi-year basis and China-domiciled applicants holding the leading positions. The field remains relatively small in absolute terms, leaving room for new entrants across multiple technology routes.
Beijing Shuowei leads a fragmented but China-concentrated field
Beijing Shuowei Photoelectric Technology holds the top position with 9 patent families, followed by Shangrao Jinko Solar Tech Development at 6 and Quzhou Microquanta Renewable Energy Technology at 5. The top five filers together account for 30% of the combined total of the hundred largest filers, signalling moderate rather than extreme concentration.
No single applicant commands a dominant share; the gap between rank one and rank five is narrow, and at least a dozen applicants sit within one or two families of each other. This tier structure indicates a genuinely competitive landscape rather than one controlled by a handful of incumbents.

The presence of solar module manufacturers (Trina Solar, Jinko Solar), emerging perovskite specialists (Microquanta, Rayleigh Solar, Brite Hellas), and energy-storage giants entering the space (Contemporary Amperex Technology) suggests the interconnection sub-field is attracting cross-sector attention as perovskite modules approach commercial readiness.
The most recent 18–24 months of filings are under-represented due to standard patent publication lag; absolute counts for 2025 and 2026 should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Rapid multi-year growth with H10K organic-semiconductor class dominant
Filing volume has grown 323% in the recent window, and the technology composition is heavily skewed toward the H10K organic-semiconductor class, which houses the core perovskite device patents.
Annual filing trend
Activity was negligible through 2018, accelerated from 2019, and reached a recorded peak of 28 families in 2024. The 2025 and 2026 figures are materially understated by publication lag and should not be read as a slowdown; the underlying growth trend remains intact.

H10K (organic semiconductors, covering perovskite device structures) accounts for the overwhelming majority of records, with H01L (semiconductor devices) a distant second. Adjacent classes — B23K (laser scribing/welding), H01G (capacitors), and H10F (photovoltaic devices) — each hold only a handful of records, marking them as under-served relative to the core.

What the competitive structure means for R&D investment
The field’s growth stage, moderate concentration, and thin coverage of process and integration classes point to specific gaps where early IP positioning would face limited prior-art density.
Growth stage: filings rising on a multi-year basis
The lifecycle evidence classifies this field as Growth, with annual filings still rising and recent years understated by publication lag. A 323% growth rate over the recent window confirms the field has moved well beyond inception but has not yet reached the filing-plateau phase typical of mature solar sub-technologies. Early movers still have a realistic window to establish foundational positions.
Growth stageFragmented top tier — no entrenched gatekeeper
The top five filers hold 30% of the hundred largest filers’ combined total, and the leader’s margin over rank five is only five families. This fragmentation means no single entity can effectively block a new entrant through sheer portfolio breadth. However, the most-cited patent (20 forward citations) on perovskite solar cell module fabrication does represent a reference point that new claims must design around.
Moderate fragmentationMinimal co-filing activity detected — ecosystem largely siloed
The only confirmed co-applicant pair in evidence is Contemporary Amperex Technology (CATL) and its wholly-owned research institute, Contemporary Amperex Future Energy Research Institute (Shanghai). This single internal collaboration suggests the field has not yet developed the cross-institutional joint-development partnerships common in more mature photovoltaic sub-sectors. Consortia or university–industry tie-ups remain an open strategic lever.
Low collaboration densityChina leads filings; US and EPO offer meaningful secondary coverage
China accounts for the largest share of patent records, followed by the United States and the European Patent Office (EPO). WIPO PCT filings indicate some applicants are pursuing broad multi-jurisdiction protection. Japan, Canada, India, and Taiwan each have minimal coverage, suggesting underprotected markets for non-Chinese filers willing to extend their portfolios.

Beijing Shuowei and Jinko Solar anchor the top tier with H10K focus
All momentum leaders are new entrants, confirming the field’s recent emergence. The two leading applicants diverge in technology emphasis: the top filer is concentrated in organic-semiconductor device structures, while the second-ranked player brings established solar-module manufacturing scale.
Beijing Shuowei Photoelectric Technology
Holds 9 patent families, the largest portfolio in scope, entirely concentrated in H10K organic-semiconductor classes (device structure H10K30, fabrication H10K71, and sub-class H10K39). Momentum trend is flagged as a new entrant with 8 recent families, indicating its entire position has been built in the current growth wave. This depth in H10K suggests a focus on cell-level interconnection architecture within the perovskite stack.
families: 9Shangrao Jinko Solar Tech Development
Ranked second with 6 patent families. Jinko Solar’s perovskite interconnection activity is a strategic extension of its dominant position in conventional silicon modules. Its entry into this space, as a new entrant in momentum terms, signals that Tier-1 module manufacturers view interconnection IP as a competitive necessity ahead of perovskite module commercialization.

Under-served branches adjacent to the dominant H10K core
Several IPC classes appear in the corpus at low counts relative to H10K, indicating that interconnection-relevant technical problems in these areas have attracted limited dedicated filing. These are observations of relative sparsity; entry-path viability depends on individual capability.
B23K · Laser scribing and interconnection patterning
With only 6 patent records in the B23K welding, soldering, and brazing class, laser-based scribing processes — the primary tool for P1/P2/P3 scribing in monolithic perovskite modules — are under-patented relative to the device-structure filings. Laser scribing determines dead-area width and ultimately module aperture ratio, making it technically consequential. Applicants with laser-process expertise (e.g., Jidu Guangneng has already staked a partial claim) could differentiate by filing process-parameter and beam-profile claims in this sparsely covered branch.
Search this in Eureka →H10F · Photovoltaic and light-sensitive device integration
H10F, which covers photovoltaic device structures beyond the organic-semiconductor framing of H10K, holds only 4 patent records here. As perovskite-silicon tandem architectures mature, the interconnection schemes specific to two-terminal and four-terminal tandems will need a classification home that may sit in H10F rather than H10K. This is an early-stage observation: the sparsity could reflect classification practice rather than a true gap, but it merits monitoring as tandem module interconnection claims proliferate.
