The core of Day4 Energy’s technological advantage
is the proprietary and patented Day4 Electrode
that is used to inter-connect photovoltaic (PV) cells
and collect the power they generate. This technology
represents a fundamental change in the way that both
PV cells and PV modules are built.
The Day4 Electrode is comprised of a polymer film
embedded with a number of specially coated copper
wires. These wires are coated with a proprietary
low-temperature melting point alloy and are designed
to establish a low-resistance electrical contact
with the surface of the PV cell. The Day4 Electrode
is a direct replacement of the conventional PV cell
soldering process that is currently widely used in
the industry.
By reinventing the way solar modules are constructed,
the Day4 Electrode improves power output, lifetime
and aesthetic appearance. At the same time, the
Day4 Electrode represents an enabling platform
for design and commercial implementation of the
next generation of PV cell concepts that is not
possible with the current solder-based approach
to module assembly.
Day4 products allow for some of the industry’s
leading levels of performance in terms of energy
generated per rated watt of power. These performance
levels are validated by on-going third party field
performance data at various test sites around the
world. Day4 Energy continues to focus efforts on
research and development in the quest to advance
photovoltaic technology and achieve cost parity for
solar energy.
