TECHNOLOGY

TOPCon

Latest generation of industrial scale PV tech designed to maximize efficiency and longevity

SiXNY Coating

Silicon nitride coating protects the cell from moisture and increases light harvesting efficiency

AlXOY

Atomic-layer alumina back-passivation slashes surface recombination for ultra-high efficiency

P+ Emitter

A thin boron doped polysilicon region used to increase the harvesting efficiency of higher energy photons

N-Type Wafer

Ultra-pure single crystal silicon with excess negative charge from phosphorus. N-type silicon delivers high lifetime, light induced degradation free power.

Tunnel Oxide

Nanometer scale SiOX barrier that blocks recombination while letting electrons quantum tunnel

N+ Poly-Si

Conductive layer deposited on the tunnel oxide to selectively collect charge carriers

Metal Contacts

Screen-printed Silver/Aluminum busbars gather current with minimal shading

Company

T1 Energy is an Austin-based manufacturer building the energy future.
