Perovskite Device Architecture Optimization Patent Snapshot
The indexed corpus for perovskite device architecture optimization currently contains a single patent family, filed by South China University of Technology in 2023 and classified under organic semiconductor technology. At this corpus size, no meaningful concentration, trend, or competitive structure conclusions can be drawn; a broader search scope or additional filing time may be needed to surface the full activity in this area.
South China University of Technology is the sole filer in this narrow corpus
South. China University of Technology holds the only patent family in this corpus, making it the ranked leader by default. No multi-applicant visible assignee structure can be assessed from a single record.
With one applicant and one family, the top five filers’ share of the ranked applicants visible in this query is 100%, but this figure reflects corpus size rather than genuine market concentration.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | South China University of Technology | 1 |
The leader’s position implies early-stage or highly specialized activity; the absence of competing filers suggests either that perovskite device architecture optimization is framed too narrowly for current patent classification, or that broader filings exist under adjacent search strings not yet captured here.
Recent years are subject to patent publication lag of 18–24 months, so activity filed in 2024–2025 may not yet be indexed; the apparent gap after 2023 should not be read as inactivity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2023 filing defines the current trend and technology mix
The annual filing trend and technology composition both reflect a corpus of one family. These charts establish a baseline reference rather than a trend narrative.
Annual filing trend
One family was filed in 2023; all other years from 2017 to 2026 show zero activity in this corpus. Years 2024–2026 are likely under-counted due to publication lag and should not be interpreted as confirmed absence of filing activity.

一种结晶和光学优化的钙钛矿太阳电池制备方法及其应用
本发明属于太阳电池技术领域，具体涉及一种结晶和光学优化的钙钛矿太阳电池的制备及其应用，包括以下步骤：S1.在含阴极层的基底上施加电子传输层，并进行首次退火，形成中间元件1；S2.对所述中间元件1施加一定体积配比的溶剂的钙钛矿吸光层，并进行二次退火；形成中间元件2；S3.对所述中间元件2施加空穴传输层，并真空蒸镀阳极中间层和阳极，得到产物。本发明采用特定的钙钛矿溶剂配比(DMSO:DMF＝5:1‑3:1)，有效控制晶粒尺寸，提高透光率，还能通过有机溶剂辅助退火技术，促使晶界减少、晶粒重结晶，提高光电转换效率，并结合光子晶体层，有效控制太阳电池发热，降低能量传输损耗。 (excerpt from the patent abstract)
Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
South China University of Technology
South China University of Technology holds 1 patent family in this corpus, classified under H10K30 and H10K71 (organic semiconductor fabrication and process). The applicant is flagged as a new entrant in momentum tracking, reflecting a first filing in the 2023 record window with no prior-period baseline. No trajectory beyond this single data point can be established.
families: 1No challenger identified
The corpus contains no second-ranked applicant. A challenger card cannot be populated from the available evidence. Researchers seeking competitive alternatives should broaden the query to related IPC classes or synonymous technology descriptors.
families: —Frequently asked questions
The current corpus contains 1 patent family. This is a very narrow result and likely reflects a tightly framed search query; researchers should expand synonyms or related IPC classes to capture the broader literature.
South China University of Technology is the sole and therefore top-ranked applicant, holding 1 patent family classified under organic semiconductor technology (H10K).
The single family in this corpus has a trend-year label of 2023. Representative patent CN116801689A is associated with this record.
The filing is classified under H10K, which covers organic semiconductors including OLED-related technology. Specifically, the applicant’s focus spans H10K30 and H10K71, relating to organic semiconductor device structures and manufacturing processes.
Only China is represented in this corpus, with 1 patent record filed there. No international counterparts under PCT, EPO, or US offices appear in the current indexed set.
No. The zero values for 2024–2026 in the annual trend reflect patent publication lag of 18–24 months, not confirmed absence of filing activity. Any applications submitted in those years may not yet be publicly indexed. The 2023 single filing should be treated as a baseline, not a peak.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
