What Solaer does
Solaer, operating under the legal name SolaEon, is a privately held perovskite solar cell developer. According to the detailed source data, the company is based in Shenzhen, China, though firmographic metadata lists a Spanish registration in Motilla Del Palancar — an unresolved inconsistency in the available record. The company's sole disclosed technical achievement is a certified 27.87% power conversion efficiency for a single-junction perovskite solar cell, measured on a 0.076 cm² unit cell with an 87.61% fill factor and validated by China's National Photovoltaic Industry Metrology and Testing Center. This result places the device meaningfully below the theoretical single-junction perovskite efficiency ceiling of approximately 33%, indicating headroom for further R&D.
The company's product surface is narrow: one core product — a high-efficiency single-junction perovskite solar cell — with no disclosed module, tandem, or commercial product offerings. There is no public pricing, no disclosed customers, no sales or distribution channels, no marketing channels, no funding rounds, no parent company, and no ownership structure disclosed beyond an apparent independent start-up status. Headcount is reported at 1–10 employees. The company explicitly acknowledges that significant challenges remain before its lab-level performance can be translated into commercially viable products, positioning it firmly in a pre-commercial, R&D-stage posture.
The business model is therefore not yet defined commercially. No revenue model, pricing structure, customer segments, or go-to-market motion is articulated in the available data. One senior project manager (Ron Ben-Chaim) is named, but no broader management team, scientific advisory board, or institutional investors are disclosed. The remaining content in the input set pertains to Zelestra, an unrelated large-scale renewable energy independent power producer, and does not establish any commercial relationship with Solaer/SolaEon.

Solaer competitors and assessment
Company assessmentBroad incumbents
- Trinasolar: Top-tier global solar module manufacturer with a published perovskite tandem programme; relevant incumbent peer pursuing the same high-efficiency cell roadmap as Solaer.
- Hanwha Qcells: Tier-1 crystalline silicon module manufacturer with an active perovskite tandem roadmap (formerly via CUBICPV); broader incumbent competing in adjacent next-gen PV technology.
- First Solar: Largest thin-film (CdTe) solar manufacturer with a perovskite R&D programme; competes for the same next-generation PV market with much greater scale and a 20%+ gross margin operating model.
- LONGi Green Energy: World's largest monocrystalline silicon cell/module producer with active R&D in perovskite tandems; comparable as a well-resourced competitor pushing into the same next-gen PV space.
Direct peers
- Renshine Solar: China-based perovskite tandem cell developer that has also reported world-record-class efficiencies — a direct domestic competitor in single-junction and tandem perovskite R&D.
- Swift Solar: US-based perovskite tandem startup pursuing high-efficiency, lightweight perovskite devices — closely comparable technology focus and early-stage profile to Solaer.
- Oxford PV: Closest direct competitor — the leading commercial-stage perovskite-on-silicon tandem solar cell developer, competing head-to-head with Solaer in next-gen perovskite cell R&D and commercialization.
- Saule Technologies: Polish perovskite solar cell developer focused on inkjet-printed flexible perovskite cells; comparable early-stage perovskite-only player pursuing efficiency and pilot-scale commercialization.
- CubicPV (CUBICPV): Perovskite-on-silicon tandem developer acquired by Qcells; a direct technology peer in the race to commercialize high-efficiency perovskite tandems.
Emerging players
- Caelux (First Solar): First Solar's perovskite tandem subsidiary focused on high-efficiency tandem cells; directly comparable perovskite device work, currently in pilot-line commercialization.
