Quantum Black Butterfly

The Quantum Black Butterfly is an innovatory plastic-based photovoltaic (PV) system with significant advantages - including double the conversion efficiency - over conventional Silicon and GaAs PVs.

The Quantum Black Butterfly (QBB) has been developed over the last 20 years by groups from Imperial College and follows a number of important breakthroughs in photovoltaic research.

Based on work undertaken in the late 1990s and early 2000’s, the QBB uses a unique patented Multiple Quantum Well and Quantum Dot approach, coupled with advanced non-tracking optical designs.

Led by Prof Keith Barnham and Dr Barry Clive, over 20 years of intense R&D has proven the QBB can achieve 41% conversion efficiency in the labs with a target of 51% within 2 years. It uses recyclable PET - the same plastic in the 1.3 billion plastic bottles sold by the soft drinks industry every day.  

The QBB has significantly lower panel cost and comparable Balance of Systems (BoS) costs to conventional PVs with an estimate of twice the conversion efficiency.

Key Features & Benefits:

Breaking Traditional Conversion Efficiency Limits

Conversion efficiencies at least 2 times better than conventional large-scale PVs.

Lower BoS Costs

The full cost associated with the build of the photovoltaic system is reduced.

Lower Operations and Maintenance Costs

Requires less maintenance - especially if accompanied by the Solaris coating.

Adapted to Use Recyclable Plastics

Uses PET plastics as a feedstock which provides an alternative recycling route.
