Challenges, Risks, and Strategic Opportunities
Thin-film photovoltaic (PV) engineering faces a complex landscape of challenges and risks in 2025, but these are counterbalanced by significant strategic opportunities. The sector’s primary technical challenge remains the efficiency gap between thin-film technologies—such as cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and emerging perovskites—and conventional crystalline silicon PV. While thin-film modules offer advantages in flexibility, weight, and potential for lower manufacturing costs, their average conversion efficiencies still lag behind mainstream silicon, which can impact large-scale adoption and investor confidence (National Renewable Energy Laboratory).
Material supply chain risks are also prominent. Thin-film PV relies on critical raw materials like indium, tellurium, and gallium, which are subject to geopolitical supply constraints and price volatility. For example, the limited availability of tellurium and indium has led to concerns about the scalability of CdTe and CIGS technologies (International Energy Agency). Additionally, the environmental and health risks associated with cadmium use in CdTe modules pose regulatory and public perception challenges, particularly in regions with stringent environmental standards.
From a manufacturing perspective, thin-film PV production requires high capital investment in specialized equipment and process optimization. Yield losses, process uniformity, and long-term module stability remain engineering hurdles, especially for newer materials like perovskites, which are susceptible to moisture and UV degradation (pv magazine).
Despite these challenges, strategic opportunities abound. The lightweight and flexible nature of thin-film PV enables integration into building materials (BIPV), vehicles, and portable devices—markets less accessible to rigid silicon panels. The rapid progress in perovskite tandem cells, which can be layered atop silicon or other thin-film materials, offers a pathway to surpass current efficiency records and reduce levelized cost of electricity (LCOE) (Wood Mackenzie).
- Strategic partnerships between thin-film innovators and established construction or automotive firms can accelerate market penetration.
- Investment in recycling and circular economy solutions for thin-film modules can mitigate material supply risks and address end-of-life concerns.
- Government incentives and targeted R&D funding, especially in the US, EU, and China, are expected to drive commercialization and scale-up efforts in 2025 (International Energy Agency).
In summary, while thin-film PV engineering in 2025 must navigate efficiency, supply chain, and regulatory risks, the sector’s unique attributes and ongoing innovation position it for strategic growth in emerging and specialized solar markets.
