Perovskite tandem PV

Perovskite-silicon tandem reaches ≥10% of new-build utility-scale PV by 2032 and continues compounding

  • $4B by 2035

The callTandem is coming and cost, not stability, gates it; the only layer a young company can hold is cornered stabilisation IP module makers must license, open now.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the drivers.
  1. D1Solar builds at about 750 GW a year and silicon is near its efficiency cap, so the next drop in cost per watt has to come from a new cell.
  2. D2Stability is already good enough to pass IEC 61215, Hanwha with TÜV and Trina twice, so the remaining limit is cost at $0.20-0.25 a watt.
  3. R1The stabilisation layer is largely covered by patents held by Trina, 3M and DuPont, so the one capturable layer may already be owned.
  4. R2A tier-1 in-sources the chemistry and stability becomes an evaluation fee with no royalty; I put that at about 25%.
  5. R3Chinese tandem-specific capacity converts, with Jinko's Jun 2026 record on a shipping TOPCon platform the narrowing signal.
  6. C1A GW-class tandem line at Qcells, Jincheon or Thalheim entering production, the first non-pilot tandem module supply for utility solar.H1 2027
  7. C2One tandem module completing the full IEC 61215 protocol at a second independent lab, which makes the chemistry bankable.end-2027

  • 22 Jun 2026Tandem solar is gated on cost not stability, and the only place a startup holds value is a licensed stabilisation-IP layer the big module makers have to pay for.
