University of Sheffield UK

Overview

The University of Sheffield, in collaboration with Power Roll (UK) and Dyenamo AB (Sweden), has launched an international project focused on lightweight solar power. This initiative aims to leverage Power Roll’s patented micro-groove solar film technology to unlock untapped markets, such as lightweight commercial rooftops and building facades, previously inaccessible to conventional PV. This is a crucial endeavor to accelerate renewable energy deployment in urban environments.

In Depth

Key Findings

The University of Sheffield, in partnership with UK-based Power Roll and Sweden’s Dyenamo AB, has launched a new international project dedicated to the development and deployment of lightweight solar photovoltaic (PV) solutions. This collaboration aims to harness Power Roll’s patented micro-groove solar film technology to unlock vast, previously unexploited markets such as lightweight commercial rooftops and building facades, which are often inaccessible to conventional PV panels due to weight and installation constraints. The project holds significant potential to accelerate the adoption of renewable energy in urban settings.

Technical / Clinical Details

At the core of this project is Power Roll’s unique micro-groove solar film technology. This technology enables the formation of solar cells on an extremely thin and flexible film, achieving dramatic weight reduction and flexibility compared to traditional glass-based silicon panels. The micro-groove structure is designed to enhance light capture efficiency, allowing for high power generation with minimal material usage. This makes it ideal for existing buildings with limited load-bearing capacity, curved structures, and even mobile applications where traditional solar PV installation has been challenging. Dyenamo AB contributes its expertise in perovskite solar cell materials, aiding in performance enhancement and ensuring the stability of the films. Researchers at the University of Sheffield will leverage their knowledge in materials science, device physics, and manufacturing process optimization to further boost the efficiency and lifespan of these innovative films. This three-party collaboration establishes an integrated approach from R&D to practical implementation.

Background & Context

As the global transition towards carbon neutrality accelerates, solar power is gaining prominence as a key renewable energy source. However, the weight and rigidity of conventional solar panels have posed significant challenges for deployment, particularly in urban areas on existing buildings and architecturally sensitive structures. Many commercial buildings and factories have load-bearing limitations on their roofs, preventing the installation of large-scale solar PV systems. Lightweight and flexible thin-film solar cells have the potential to fill this market gap, but they have faced challenges in terms of cost, efficiency, and durability. This international project seeks to provide a comprehensive solution to these issues by combining cutting-edge perovskite technology with innovative film manufacturing techniques. It exemplifies Europe’s proactive engagement in clean energy technological innovation and market expansion.

Strategic Significance & Outlook

Lightweight solar film technology is expected to see significant growth across a wide range of applications, including Building-Integrated Photovoltaics (BIPV), off-grid solutions, and mobile applications such as automotive and drones. This project aims to further mature Power Roll’s technology and develop market-ready products to establish competitiveness in these sectors. Future focus areas will include demonstrating long-term film durability, scaling up manufacturing processes, and further reducing production costs. This international collaboration has the potential to dramatically broaden the applicability of solar power and accelerate the adoption of renewable energy in urban environments, thereby making a substantial contribution to achieving a sustainable society.
