Glazing-integrated photonics

One physics claim, two end markets.

The callThe physics works on both sides and the business mostly doesn't: developers buy cheaper glass plus rooftop panels, and growers haven't shown the film pays.

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 restraints.
  1. D1Buildings are told to make their own power, and in a city most of a tower's sun falls on glass; rooftop panels cover a sliver.
  2. D2A clear film laminated into standard glass on the glass majors' lines could steer chosen wavelengths to hidden cells, and the same trick converts light for crops.
  3. R1Ubiquitous Energy passed 10% efficiency at 90% transparency, got 2 installations in a decade and shut in 2026: the demand verdict.
  4. R2View, the one smart-glass company to list (a $1.6B SPAC), went bankrupt in 2024.
  5. R3The greenhouse side is an additive in a commodity film market where UbiQD is already in position, so it earns materials margins.
