Day4 Electrode® –
Leading Edge Solar Electric Technology

The core of Day4 Energy’s technological advantage is our 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.
