IntriEnergy Newsletter June 2024

European Patent Update – IntriEnergy Tandem Junction Photovoltaic Cell 

In our last newsletter, IntriEnergy reported the European Patent Office had issued a Notice of Intent to Grant our tandem junction photovoltaic cell patent.   We continued to work with our patent attorney to determine the best countries in which to activate our patent based on market potential and they are currently filing on our behalf.  Having already secured out patent protection in the USA, Canada, and India, the additional EU countries will significantly expand our IP protection. 

A key objective for the project was to develop a database of formulations to determine the optimum multi-layer anti-reflective coating (ARC).  A majority of the project was focused on this critical task.  It involved a reiterative process of growing single layer films with specific parameters and measuring the results and moving to repeating the process growing double layer films.   We are currently working with Georgia Tech to analyze the results and finalize the optimum formula for our multi-layer anti-reflective coating.  As we complete this activity, we will be in the position to design the appropriate sequencing of multiple layers to be used in solar cell manufacturing.   


As we communicated in our previous newsletter, the overall project goal is to demonstrate IntriEnergy’s anti-reflective coating on industry standard N-type solar cells to do a side-by-side comparison demonstrating IntriEnergy’s enhanced photon capture and increased energy output.  We are targeting this to be achieved in Q3 of this year. 

PV Efficiency 40% Record Tandem Cell

Tandem Junction PV Cell Development 

In the last newsletter we reported the feasibility of our innovative layer structure for Silicon Carbide and demonstrated an increase of 40% in power from a standard structure PV device. Our next step is to test our Silicon Carbide structure on alternative solar cell structures where the properties of SiC can improve efficiencies, in particular HIT cells and tandem cells.

We will continue to keep you informed of our progress on these projects.
