Perovskite Device Simulation Patent Landscape 2026
The perovskite device simulation patent space is in a Growth stage, with the field expanding strongly on a multi-year basis, though annual volume has eased from its 2023 peak. The landscape is academically concentrated, with City University of Hong Kong, Hanwha Solutions, and several university research foundations holding the leading positions.
Academic institutions dominate a still-nascent but rapidly growing field
City University of Hong Kong leads all applicants, followed by Hanwha Solutions Corp as the only major industrial entrant in the top tier. The University of North Carolina at Chapel Hill and the Arizona Board of Regents share third position, with universities and research foundations accounting for the majority of the top-ranked filers.
The top five filers account for 38% of the combined patent records of the hundred largest filers, indicating a moderate concentration. There is a clear tier gap between the leader’s position and the mid-table filers, most of which hold only two or three patent records.

The dominance of academic and quasi-academic entities suggests that core simulation IP is still being established through publicly funded research, leaving space for industrial players to enter or co-develop proprietary simulation methods.
The most recent 18–24 months are likely under-counted due to standard patent publication lag; 2024–2026 figures should be read as provisional minimums rather than final totals. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2023 filing surge anchors multi-year growth; organic semiconductor IPC dominates the mix
Annual filing activity and technology branch composition together show both how quickly the field mobilized and where simulation work is being anchored technically. The two charts reveal a field that peaked sharply in 2023 and sits overwhelmingly within organic semiconductor and photovoltaic device classifications.
Annual filing trend
Filing volume was negligible through 2018, accelerated from 2019 onward, and reached its highest annual count in 2023. The 2024–2026 bars are understated by publication lag and should not be read as a plateau or decline; the three-year recent window remains well above the prior three-year window.

What the landscape structure means for R&D investment decisions
Three structural signals—life-cycle stage, concentration pattern, collaboration activity, and geographic spread—together define where the highest-leverage entry points and competitive risks currently lie.
Growth stage with annual volume eased from 2023 peak
The field is classified as Growth, with recent three-year filing volume well above the prior three-year window. Annual counts have eased from the 2023 high, consistent with a field consolidating after an initial surge rather than declining. New entrants are still arriving, and no single technical approach has yet achieved blocking coverage.
Growth stageModerate concentration with a clear academic-industrial split
The top five filers hold 38% of the combined records among the hundred largest filers, a moderate level that leaves meaningful room for new entrants. The only major industrial filer in the top two is Hanwha Solutions Corp; most other leaders are universities or research foundations, which means industrial simulation IP remains relatively underdeveloped and competitively accessible.
Moderate concentrationThree notable co-filing partnerships anchor the collaborative core
The most active co-filing pair is the University of North Carolina at Chapel Hill with the Arizona Board of Regents, sharing six joint patent records. City University of Hong Kong and Imperial College Innovations Ltd share five records, as do the Research and Business Foundation of Sungkyunkwan University and the Global Frontier Centre for Multiscale Energy Systems. All three partnerships are cross-institutional and academic, suggesting that collaborative simulation research is the dominant mode of IP generation in this field.
Academic partnershipsUS and EPO lead filings; India is the third-largest national office
The United States is the leading filing jurisdiction, followed by the EPO and India, with China and WIPO PCT filings at notably lower counts. India’s presence as the third-largest office is distinctive and likely reflects active university research programs at institutions such as the National Institute of Technology Patna. South Korea, Australia, and the UK each appear with minimal counts, indicating limited regional protection strategies outside the US–Europe axis so far.

Under-served adjacent branches in software modeling and precursor chemistry
Several IPC branches appear at low counts relative to the dominant organic semiconductor core. These represent areas where simulation-adjacent work exists but dedicated IP coverage is thin, making them worth monitoring for entrants with complementary capabilities.
G06F · Electric digital data processing for device modeling
With only 4 patent records, G06F is sparsely covered despite being the natural classification home for simulation software, numerical solvers, and digital-twin architectures applied to perovskite devices. The top-cited patent referencing a digital twin system for perovskite design verification signals plausible technical value. An entrant with software or CAE expertise could establish differentiated IP in this branch before the computational modeling thread consolidates under H10K.
Search this in Eureka →C01G · Compounds of other metals (perovskite precursor simulation)
C01G holds only 3 patent records, indicating that simulation of precursor chemistry and metal-compound synthesis routes for perovskite formation is largely unclaimed as IP. Given that crystal control and stability is the most-cited theme in the landscape, there is a plausible technical connection between precursor simulation and device performance prediction. Entry requires chemistry modeling capability combined with experimental validation, but the low existing count suggests limited blocking risk.
