Tandem PV product offering
Product offeringCore offering
Tandem PV designs and manufactures perovskite-silicon tandem solar panels that stack a thin-film perovskite light-absorbing layer on top of conventional silicon cells, achieving approximately 30% higher power output than standard silicon panels. The company operates a commercial demonstration factory in Fremont, California with 40 MW annual nameplate capacity, sells panels directly to Independent Power Producers (IPPs) for utility-scale deployments, and offers technology licensing/partnerships to established solar manufacturers.
Product overview
Tandem PV offers a single unified product line centered on its perovskite-silicon tandem solar panel technology. The company's flagship offering is its high-efficiency tandem solar panels that combine thin-film perovskite with conventional silicon solar cells. These panels achieve approximately 30% higher efficiency than standard silicon panels (29.7% efficiency in current production, with 30.4% demonstrated on mini-modules). Tandem PV also offers a technology licensing program for established solar manufacturers to integrate the perovskite layer into their existing silicon panel designs, providing process expertise and materials know-how. The company operates a commercial demonstration factory in Fremont, California with 40 MW annual nameplate capacity, and initially targets utility-scale deployments through independent power producers (IPPs) as primary customers.

Tandem PV competitors and assessment
Company assessmentRegional players
- EneCoat Technologies: Japan-based perovskite solar cell developer with similar tandem technology ambitions. Comparable as a regional perovskite PV competitor not directly serving the U.S. utility-scale market.
Direct peers
- Oxford PV: UK/Germany-based pioneer in perovskite-silicon tandem solar cells and modules, generally considered the global leader in commercializing this architecture. Directly comparable to Tandem PV in technology approach, target customer (utility/rooftop), and go-to-market stage.
- Caelux: U.S.-based perovskite-silicon tandem cell developer acquired by First Solar. Targets the same perovskite-on-silicon tandem architecture with similar U.S. manufacturing ambitions, making it a directly comparable technology peer now backed by an incumbent thin-film leader.
- Swift Solar: U.S. early-stage perovskite-silicon tandem startup developing high-efficiency tandem modules. Closely comparable in technology focus, U.S. origin, and pre-commercial scale, though at an earlier stage than Tandem PV.
- Saule Technologies: Poland-based perovskite PV developer focused on indoor/BIPV and tandem applications. Comparable technology stack (perovskite-based PV), though currently focused on different end markets than Tandem PV's utility-scale deployment focus.
Broad incumbents
- First Solar: U.S.-headquartered incumbent thin-film (CdTe) module manufacturer with multi-GW scale and major U.S. manufacturing footprint. Relevant as a broader incumbent in advanced PV and as the parent of Caelux; competes for utility-scale projects and DOE funding.
- Hanwha Qcells: Global silicon PV manufacturer with significant U.S. manufacturing presence. Relevant as a likely Tandem PV licensing/customer partner and as an incumbent competing for utility-scale solar procurement.
- SunPower: U.S.-headquartered residential and commercial solar company with module manufacturing heritage. Relevant as a broad incumbent in U.S. solar where Clemens Hofbauer previously held senior manufacturing leadership.
- LONGi Green Energy: World's largest silicon wafer and module manufacturer, headquartered in China. Sets the cost-efficiency benchmark Tandem PV must beat; also pursuing tandem architectures, making it both a competitor and the reference baseline for industry cost curves.
- JinkoSolar: Top-tier global silicon PV module manufacturer with large-scale manufacturing. Relevant as a dominant low-cost incumbent whose pricing and capacity expansions directly shape Tandem PV's competitive context in utility-scale procurement.
