A LIGHTWEIGHT, FLEXIBLE PIECE OF THE BIG PUZZLE

TACKLING THE PUZZLE

Everyone knows we need to transition from fossil fuels to renewable energy.

But it's not an easy task.  Moving to green energy is a complex puzzle, full of political, social, technological and financial challenges. 

Our piece in this puzzle is to offer something different. 

To make solar that goes where other solar solutions can't.  And to do it without using rare and precious earth materials.


Of course, our technology on its own won't solve the problem - but it's part of a longer journey to make solar an obvious and irresistible choice for green energy transition.

HOW IT WORKS

Here comes the magic equation.

(MICROGROVES + PEROVSKITES + FILM) x LOW COST PROCESS 
=
LIMITATIONS REMOVED

Dr John Topping’s original idea was to combine Microgrooves with a vacuum coating process like that used in food packaging. This would create a lightweight film for a host of electronic applications, including photo-voltaic (PV) solar modules.  

CLEVER IDEA.

Lightweight film tackles a major limitation of traditional solar panels – heavy weight and lack of flexibility.

To reduce the vast quantity of rare earth minerals used in traditional solar, we decided to work with Perovskites.

Abundant and efficient in absorbing and convert sunlight into energy.

Finally, we needed a lower-cost production method.  Enter roll-to-roll production.  A known process, well-established and easy to scale.

GOOD NEWS.

WIN-WIN.

ROLL ON. 

SOUNDS SIMPLE.  ACTUALLY ISN'T.

Our approach

This totally unique combination which eliminates the limitations of existing solar solutions sounds simple. 

 

But it's only been possible with many years' pain-staking development and huge commitment from our people, partners and investors.

HOW DOES IT DIFFER TO TRADITIONAL SOLAR?

01.

UNIQUE TECHNOLOGY

Flexible, lightweight and made from abundant materials. Microscale cells are 1/50th the width of a human hair.

02.

NO TCO LAYER

We don't use TCO (Transparent Conductive Oxide). It's an expensive component in traditional solar. 

03.

BETTER IN THE SHADE

Our cell architecture means modules are less impacted by shade or low light.

04.

RESISTS DEFECTS

Damage to one part of a module doesn't impact overall performance - a common issue for traditional solar.

WHERE CAN OUR FILM BE USED?

Typical applications 

Power Roll Non-load bearing rooftop solar

NON-LOAD BEARING ROOFTOPS

At least 30% of all commercial rooftops around the globe can't support traditional solar - that's over 25bn m2.

Power Roll Off Grid solar

OFF-GRID LOCATIONS

Providing clean electricity to people and places without access to the grid.

Power Roll Agri-tech solar

AGRI-TECH

Transitioning from traditional diesel powered solutions.

Power Roll Floating and marine solar

FLOATING & MARINE

Turning large expanses of water into energy generation substations. 

Power Roll Built Environment solar

THE BUILT ENVIRONMENT

Supporting the construction industry to integrate greater levels of  solar into major new build projects (BIPV and BAPV).
