We carry out all our research and manufacturing in a way that minimises our environmental impact. Our solar cells reduce the resource intensity of a photovoltaic installation – we achieve this by sourcing and operating responsibly, and by designing a resource-efficient product.
Our perovskite technology will help upscale solar energy quickly to meet the ambitious targets needed to tackle the climate crisis.
Our material can be manufactured using existing processes, making perovskite ideal for use as a plug-and-play partner to conventional silicon technology.
We use raw materials that are abundant and won’t deplete the earth.
The shift to a clean energy system is driving a huge increase in the requirements for critical minerals (see IEA 2021 report). While many companies are only thinking about this challenge now, we considered and planned for it from day one. We wanted to power solar photovoltaics at the terawatt scale. So when we first engineered our perovskite, we chose ingredient elements that are globally abundant for decades to come, and we do not source from conflict countries.
The manufacture of solar panels and their components must respect and uphold human rights. We do not tolerate violations of ethics and dignity. We strongly condemn the use of forced labour anywhere in the PV supply chain (read our statement on forced labour).
We carefully select our suppliers for our manufacturing operations based on their sustainability credentials, making sure that they fulfil the transparency, accountability, and human rights standards we require. Most of the raw materials for our solar cells come from Europe, where our production plant is located.
Solar PV already has much lower lifecycle emissions compared with fossil fuels. Currently the majority of greenhouse gas emissions from PV installations come from materials extraction/processing and module manufacturing. While we do not produce modules, we want to help further reduce the carbon footprint of the wider solar industry by working with module manufacturers with strong sustainability credentials and who produce and supply locally to where their modules will be installed.
We have designed our product to meet high sustainability standards throughout its lifecycle.
Firstly, we have engineered our perovskite solar cell to be highly resource-efficient. Adding an equivalent of 0.5% by weight of our perovskite material onto a conventional silicon PV cell would enable a solar module to produce 20%–50% more power over its lifetime. This higher power output could also offset the carbon footprint embodied in the production of high-purity silicon needed for photovoltaic cells.
Another important aspect is end-of-life care – solar panels with our product can be recycled using the same technology for current PV modules. We are also engaged in discussions with industry bodies such as PV Cycle to ensure modules with our solar cell product meets or exceeds the recyclability requirements as conventional silicon PV modules.
Through independent analyses, we continue to conduct lifecycle studies on our solar cells. Results have shown that our perovskite solar technology will have a positive impact on the environment by using resources more efficiently (link).
Moreover, we apply a robust environmental management system to ensure that we integrate environmental considerations into every aspect of our business processes and operations. Our factory in Brandenburg is certified to the ISO 50001 energy management standard, which enables us to continually measure and improve our energy efficiency.
