The new R&D facility will keep First Solar’s technology roadmap on track without disrupting its commercial manufacturing operations. It is designed to facilitate innovation in developing and producing high-performance thin film photovoltaic semiconductors, which are anticipated to be fundamental in the next generation of advanced photovoltaics. Alongside its facilities in the U.S., First Solar operates factories in Vietnam and Malaysia and is constructing a new manufacturing facility in India, which is projected to start operations in the second half of 2023. These expansion efforts aim to achieve over 20 GW of annual global manufacturing capacity by 2025.
In addition to these developments, as of 2023, First Solar has partnered with the REMADE Institute to initiate high-value recycling research and development projects. This collaboration focuses on developing recycling technologies for crystalline silicon modules and aims to enhance glass and aluminum recycling, thereby contributing to a more sustainable solar energy industry.
Innovative Technology
Thin Film CadTel (Cadmium Telluride)
Thin film CadTel (Cadmium Telluride) photovoltaic (PV) technology has shown various qualities since its introduction. These qualities encouraged First Solar to choose this technology over more conventional technologies such as crystalline silicon (c-Si).
Even though thin-film CadTel technology has made significant progress over the previous two decades, its full potential has not yet been achieved. First Solar’s research and product development teams anticipate that thin-film CadTel will be able to achieve a cell efficiency of 25% by 2025 and that there will be routes to achieve a cell efficiency of 28% by 2030.
After a series of workshops in 2017, First Solar, Colorado State University, the University of Toledo, and NREL formed the U.S. Manufacturing of Advanced Cadmium Telluride (US-MAC) photovoltaics consortium in March 2021. This group’s goal is to strengthen the U.S.’s position as a leader in solar technology.
Investment in Perovskite
First Solar completed the acquisition of Evolar AB, a European company at the forefront of perovskite technology, in 2023. As part of the deal, research will continue at Evolar’s lab in Uppsala, Sweden. This will be First Solar’s first R&D facility in Europe.
Series 7 modules
First Solar planned to start its new 3.3 GWdc facility in Ohio in the first half of 2023 with a $680 million investment. The new factory will likely make the much-anticipated Series 7 modules. It will also increase First Solar’s annual output in Ohio to 6 GWdc, making it the biggest fully vertically integrated solar production complex outside China.
Sustainability Initiatives
First Solar’s Series 7 solar modules have the industry’s lowest carbon and water footprints. These modules are approximately four times more efficient in carbon and water usage than standard crystalline silicon modules made in China. Moreover, the energy payback period of these modules is five times faster, significantly reducing their environmental impact.
Solar Power Initiatives
First Solar has sold around 50 GW of PV solar panels from 2002 to 2022. The company still had a significant backlog of about 77.8 GW in July 2023. Based on average global irradiance and grid power emissions, its products are estimated to replace 83 million metric tons of CO2eq per year for more than 30 years. This achievement equates to powering over 66 million homes, planting 1.4 billion trees, and conserving over 225 billion liters of water per year, equivalent to the volume of around 96,000 Olympic-sized swimming pools.
GHG Emission
The company has set ambitious goals to minimize its operational impacts. By 2028, First Solar aims to reduce its total scope 1 and scope 2 greenhouse gas (GHG) emissions by 34%, with a long-term goal of achieving net-zero GHG emissions by 2050, compared to its 2020 levels.
The company has a continued focus on reducing environmental impacts while enhancing the efficiency and effectiveness of its solar modules, positioning it as a leader in sustainable energy solutions.
