TOPCon Solar Cell Simulation and Modeling Patent Landscape 2026
TOPCon Solar Cell Simulation and Modeling Patent Landscape
One family on record. the searched intersection of TOPCon device claims with TCAD/simulation terminology returns a single patent family, not an active sub-field with a competitive map. Counts run at zero from 2017 through the dataset midpoint of 2022, rise to one filing in 2023, and fall back to zero through the partial 2026 year. There is no growth curve to extrapolate — this is one document appearing once. Given the usual 18-month publication lag, any very recent filing in this space would not yet be visible.

Common questions
How many patents exist for TOPCon solar cell device simulation and TCAD modeling?
Within the specific search scope combining TOPCon terminology with TCAD, device simulation, or numerical modeling language and restricted to the relevant semiconductor and computational-modeling IPC classes, exactly one published patent family is returned, covering the 2015–2026 window. This is a narrow, deliberately filtered result rather than a count of all TOPCon-related patents. Broader searches on TOPCon device architecture alone return a much larger set, because most of that activity is not framed in simulation-specific claim language.
Who owns the main patent for TOPCon simulation claims?
The single documented assignee in this search scope is Georgia Tech Research Corporation, via its PCT filing WO2023235390A3 on a rear-junction bifacial poly-Si/SiOx passivated contact solar cell. The filing focuses on device architecture and manufacturing method claims — laser etching and screen printing for contact patterning — rather than a standalone simulation or software claim. No other assignee appears in this exact intersection of terms.
Why is there only one patent result for TOPCon TCAD modeling?
Most TCAD and process-simulation work for TOPCon cells is published in academic and conference literature or kept as internal process know-how rather than filed as a patent claim in this specific vocabulary. Simulation results typically support a device or manufacturing claim rather than becoming the claim itself, so they show up as description text, not as records classified under computational-modeling IPC codes like G06F30. A search built around device claims alone would return a substantially larger dataset.
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 TOPCon Solar Cell Simulation and Modeling 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.
