According to TechSci Research report, “Solar Photovoltaic Wafer Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2020-2030F”, The Global Solar Photovoltaic Wafer Market was valued at USD 14.99 Billion in 2024 and is expected to reach USD 29.59 Billion by 2030 with a CAGR of 11.82% during the forecast period. One of the most significant trends is the industry’s move from standard wafer sizes such as M2 (156 mm) toward larger formats like M10 (182 mm) and G12 (210 mm). These larger wafers enable higher power output per module, reducing balance-of-system (BOS) costs for utility-scale projects.
For instance, a 210 mm wafer can deliver modules exceeding 600W capacity, compared to 350–400W for earlier formats. This transition is supported by advances in cell cutting and module integration technologies. Manufacturers such as LONGi and Zhonghuan are leading this shift, scaling up mass production of larger wafers to meet demand from utility-scale developers. The adoption of larger wafers is expected to dominate new installations, with M10 and G12 formats projected to account for over 70% of shipments in the next few years. This trend reflects the industry’s ongoing focus on maximizing efficiency while lowering system-level costs.
The push for higher efficiency solar cells is driving demand for advanced wafers compatible with technologies like TOPCon (Tunnel Oxide Passivated Contact), HJT (Heterojunction), and IBC (Interdigitated Back Contact). These technologies require wafers with high purity, thinner dimensions, and lower defect rates. For example, TOPCon cells can achieve efficiencies above 25%, compared to around 22% for standard PERC cells, provided the wafers meet stringent quality requirements.
HJT technology, in particular, demands ultra-thin wafers, often less than 150 microns, with uniform surface properties. This trend is leading manufacturers to invest heavily in precision wafer slicing and surface treatment techniques. Companies like LONGi and JinkoSolar are already scaling wafer production tailored for next-generation cells, positioning themselves for the next wave of efficiency gains. The alignment of wafer advancements with cell innovations ensures that wafers remain central to solar efficiency improvements.
Based on Type, Gallium Arsenide (GaAs) Wafers is the fastest growing segment in the global Solar Photovoltaic Wafer market during the forecast period, due to their superior performance characteristics compared to traditional silicon wafers. GaAs wafers offer high electron mobility, direct bandgap, and excellent resistance to radiation damage, making them highly efficient for advanced solar cells. They can achieve energy conversion efficiencies of over 30%, which is significantly higher than conventional silicon-based wafers. This makes GaAs particularly attractive for aerospace, defense, and satellite applications where efficiency and durability are paramount.
Additionally, the adoption of GaAs in concentrated photovoltaic (CPV) systems is increasing as it enables better energy capture under high solar irradiance conditions. Growing investments in space exploration, coupled with the expansion of high-performance solar panels for specialized use cases, are further fueling demand. Moreover, research institutions and companies are working on cost-reduction techniques such as epitaxial lift-off and wafer reuse to address the high production costs traditionally associated with GaAs wafers. With global emphasis on maximizing efficiency, durability, and performance in solar technologies, GaAs wafers are emerging as a key growth driver in next-generation photovoltaic applications.

Based on region, Asia Pacific is the fastest growing region in the Global Solar Photovoltaic Wafer Market during the forecast period driven by ambitious renewable energy policies, decarbonization goals, and a strong commitment to reducing dependence on fossil fuels. The European Union’s “Fit for 55” package and the REPowerEU initiative aim to achieve a significant increase in renewable capacity, with solar power positioned as a cornerstone of the region’s energy transition. This policy push is creating a surge in demand for solar wafers, particularly for utility-scale projects as well as residential and commercial rooftop installations.
Germany, Spain, Italy, and France are leading solar markets in the region, with aggressive solar capacity additions supported by subsidies, feed-in tariffs, and tax incentives. Germany alone plans to reach 215 GW of solar capacity by 2030, fueling wafer demand. Southern European countries, with abundant sunlight, are accelerating large-scale solar projects, while northern Europe is increasingly adopting distributed solar systems in urban and industrial zones.
Additionally, Europe is investing heavily in reshoring solar manufacturing to reduce reliance on Asian suppliers and secure its clean energy supply chain. Investments in advanced technologies, such as heterojunction and tandem solar cells, are creating demand for high-quality, large-size wafers. The region’s emphasis on sustainability and low-carbon manufacturing is also driving innovation in wafer production processes, aligning with its broader climate objectives.
With corporate buyers and utilities signing large power purchase agreements (PPAs) and consumers adopting rooftop systems, wafer demand is expected to rise sharply. As Europe strengthens its policy frameworks, invests in local production, and accelerates solar adoption across multiple sectors, the region is poised to outpace others in growth rate, establishing itself as the fastest growing market for solar photovoltaic wafers in the forecast period.
