BOE recently gave an update on its business layout, technical indicators and follow-up plans in the perovskite photovoltaics sector.
BOE’s foray into the perovskite sector is underpinned by its long-standing display know‑how. Perovskite and display devices share similar thin‑film architectures, so BOE’s strengths in glass processing, film deposition, encapsulation and production equipment transfer naturally into perovskite manufacturing and support large‑scale, automated production.
At the Hefei site, the perovskite pilot line went from equipment installation to first sample rollout in just 38 days. In parallel, BOE has completed its core perovskite process toolkit and built a fully automated flexible perovskite line designed to balance process versatility with continuous output, laying the groundwork for future optimization and capacity ramp‑up.
On the technology side, BOE is advancing rigid, flexible and tandem perovskite modules in parallel. The full process flow is now established across three platforms: a glove‑box line for 2.5 × 2.5 cm cells, an experimental line for 30 × 30 cm devices, and a 120 × 240 cm pilot line for full‑size modules.
Recent performance numbers underscore the progress. Third‑party tests show rigid small‑area devices at a maximum steady‑state efficiency of 27.37%, while the pilot line has produced a 2.88 ㎡ module rated at 579 W, or 20.11% full‑area efficiency; on the flexible side, efficiencies reach 21.39% on the experimental line and 16.6% with 433 W output on the pilot line.
BOE is currently conducting perovskite demos in buildings and daily‑use products. The company has built a perovskite “zero‑carbon cabin” and is developing standardized BIPV elements such as PV floor and roof tiles, alongside collaborations on photovoltaic price tags and autonomous vehicles with consumer‑electronics partners.
Looking ahead, BOE says its R&D focus remains on boosting efficiency and extending perovskite device lifetimes. The next step is to push pilot‑line results into volume production, build out a full ecosystem from materials and equipment to end products, and drive costs down as perovskite moves toward large‑scale commercialization.
