01 / THE SOLAR CELL
Engineered
from the crystal up.
From precursor vapour to usable power.
Independent sources evaporate the perovskite precursors. As that vapour forms a crystalline film, we control the material composition, thickness and interfaces.
That precision creates a foundation for harvesting indoor light and integrating photovoltaics with electronics.

From the solar cell
to intelligence at the edge.
Capture the light. Manage the power. Keep a connected device working. Our development connects indoor photovoltaics with ultra-low-power electronics, IoT and edge AI.
I / ULTRA-LOW-POWER ELECTRONICS
Capture light.
Deliver usable power.
Bring photovoltaics closer to the circuit.
We are developing direct integration of perovskite photovoltaics above a power-management integrated circuit, or PMIC.
The aim is a compact power module that converts harvested light into power the electronics can use, with less dependence on repeated battery replacement.
