Next-Generation High-Efficiency Triple Junction Solar Panels for Low-Cost Energy Production

energyPrototypeTRL 3

Imagine a solar panel that acts like a three-layer cake, where each layer catches a different part of the sunlight. While current high-end panels use two layers, this project adds a third to squeeze out even more power. It also focuses on using common materials that are easy to recycle, so we don't rely on rare, expensive metals.

The business problem

What needed solving

Current silicon solar cells are hitting a physical efficiency ceiling. Businesses need a way to generate significantly more power from the same footprint without increasing costs through rare, expensive materials.

The solution

What was built

A triple junction solar cell concept using perovskites and silicon. The project is developing the building blocks for a 2-terminal device designed for scalability and recycling.

Who can put this to work

Solar Energy Manufacturing
enterprise
Target: PV Module Manufacturer

If you are a PV module manufacturer dealing with the efficiency limits of silicon cells — this project developed a triple junction design that targets efficiencies >33%. This allows you to produce more power from the same surface area using scalable processes.

Green Construction
mid-size
Target: BIPV (Building Integrated PV) Provider

If you are a BIPV provider dealing with limited roof space for clients — this project developed high-performance cells that exceed the Auger limit of silicon. This maximizes energy yield per square meter for urban installations.

Waste Management
SME
Target: Solar Panel Recycling Firm

If you are a recycling firm dealing with toxic or rare materials in old panels — this project developed design for recycling principles and reduced use of critical raw materials like silver and indium. This makes the end-of-life recovery process cheaper and cleaner.

Frequently asked

Quick answers

How does this affect the cost of solar production?

The project focuses on cost-effective processing techniques that are industrially viable and the use of earth-abundant materials to reduce reliance on expensive critical raw materials.

Can this technology be produced at an industrial scale?

Yes, the project specifically selects scalable processes for development to ensure minimal performance loss during upscaling.

What is the IP or licensing status of the triple junction design?

Based on available project data, the project is currently in the development phase (2022-2026) and focuses on establishing the value chain; specific licensing terms are not provided.

How does it handle environmental regulations?

It incorporates design for sustainability and circularity, specifically reducing critical raw materials like silver (Ag) and indium (In) to meet environmental needs.

What is the timeline for market availability?

The project runs until March 31, 2026, focusing on initiating the development of this future technology node.
