Flexible Solar Cells Expand as Buildings and Mobility Demand Lightweight Power

Flexible solar cells are gaining attention as photovoltaic technologies move beyond conventional rigid panels toward lightweight, bendable, and adaptable power-generation formats. Their ability to conform to curved surfaces and integrate with structures where traditional modules are difficult to install is opening applications across buildings, consumer electronics, transportation, aerospace, defense, and off-grid power. Advances in thin-film manufacturing are also improving their commercial potential.

A comprehensive market assessment by MarkNtel Advisors reveals that the global flexible solar cells market was valued at USD 0.54 billion in 2025 and is projected to grow from USD 0.68 billion in 2026 to USD 1.63 billion by 2032, expanding at a CAGR of 15.59% during 2026–2032. Copper indium gallium selenide (CIGS) accounts for approximately 45% of the technology segment, while plastic polymer substrates represent about 58% of the market. Asia-Pacific leads geographically with nearly 53% of global demand.

Building Integration Creates New Solar Applications

Building-integrated photovoltaics are emerging as an important application because flexible solar cells can be installed on surfaces where conventional glass-based modules may be difficult to accommodate. Lightweight films can be incorporated into façades, curved roofs, walls, glazing, and other architectural structures while offering greater design flexibility.

The European Union is also strengthening the connection between buildings and renewable-energy generation. The revised Energy Performance of Buildings Directive includes provisions requiring new buildings to be solar-ready, creating a policy environment that can support photovoltaic technologies suitable for unconventional building surfaces. The European Commission’s building-energy framework provides the regulatory context for this transition.

Flexible photovoltaic formats can be particularly relevant to renovation projects where structural load, architectural design, or available roof geometry can limit the use of conventional panels.

CIGS Maintains Technology Leadership

Copper indium gallium selenide represents approximately 45% of the flexible solar cells industry by technology, making it the leading technology segment. CIGS combines high optical absorption with mechanical flexibility and can be deposited onto substrates that are considerably lighter than conventional glass-based photovoltaic modules.

These characteristics make CIGS relevant to aerospace, defense, portable electronics, transportation, and lightweight rooftop applications. The technology has also benefited from established thin-film manufacturing experience, although emerging perovskite and hybrid architectures are creating additional competition.

The growing range of technology options is allowing manufacturers to develop flexible photovoltaic products according to requirements such as weight, efficiency, flexibility, durability, transparency, and installation environment.

Polymer Substrates Support Lightweight Solar Designs

Plastic polymer substrates account for approximately 58% of the market by substrate material. Materials such as polyethylene terephthalate, polyethylene naphthalate, and polyimide can provide the flexibility and low weight required for applications where conventional glass modules are impractical.

Polymer substrates are also compatible with manufacturing approaches used for organic photovoltaics and emerging thin-film technologies. Their flexibility allows photovoltaic layers to be integrated into curved surfaces, portable equipment, vehicles, and building materials.

The development of lightweight photovoltaic films is therefore expanding the potential installation base beyond conventional rooftops. This is particularly relevant where structural weight or surface geometry is a limiting factor.

Roll-to-Roll Manufacturing Improves Scalability

Manufacturing technology is becoming an important factor in the commercialization of flexible solar cells. Roll-to-roll production can enable continuous processing of photovoltaic films, creating opportunities to increase manufacturing throughput while potentially reducing production costs.

Japan’s New Energy and Industrial Technology Development Organization has supported development of flexible perovskite solar technologies, including wider roll-to-roll manufacturing processes. Such initiatives illustrate the industry’s shift from laboratory-scale fabrication toward larger production formats.

Improved manufacturing scalability could influence the economics of flexible photovoltaic products, particularly as developers seek lightweight solutions for building surfaces, vehicles, portable equipment, and other non-standard installations.

Perovskite Technology Broadens Future Applications

Perovskite solar technology is attracting increasing attention because of its potential for lightweight and flexible photovoltaic configurations. The material can be deposited in thin layers and combined with flexible substrates, creating opportunities for applications where weight and adaptability are important.

Commercial development is progressing alongside research into stability, efficiency, durability, and large-scale manufacturing. The U.S. Department of Energy has supported thin-film photovoltaic research through its Solar Energy Technologies Office, including programs focused on perovskite and other advanced solar technologies. The U.S. Department of Energy’s solar technology program provides information on federal research supporting next-generation photovoltaic technologies.

The development of perovskite systems could eventually broaden the flexible solar technology base, although durability, manufacturing consistency, and long-term field performance remain important considerations.

Aerospace and Defense Need Lightweight Power

Aerospace and defense applications are creating specialized opportunities for flexible photovoltaics. Conventional solar panels can add significant structural weight, while flexible cells can conform to aircraft, satellites, unmanned systems, and other irregular surfaces.

The technology can also provide power for remote sensors and communication equipment where reducing battery dependence is important. High power-to-weight ratios are particularly valuable in space applications because launch weight directly affects mission economics.

Research into flexible CIGS and perovskite technologies is therefore extending beyond terrestrial energy generation toward specialized power systems for satellites, high-altitude platforms, and defense equipment.

Consumer Electronics Encourage Smaller-Scale Applications

Wearable electronics, sensors, portable devices, and Internet of Things equipment represent another application area. Flexible solar cells can be incorporated into surfaces that move with the user or device, allowing power generation without relying entirely on conventional batteries.

The potential is particularly relevant for low-power devices operating in remote or difficult-to-access environments. Solar-powered sensors can potentially extend operating periods while reducing maintenance requirements associated with frequent battery replacement.

Although these applications generally require smaller power outputs than building or utility-scale systems, they broaden the addressable market for flexible photovoltaic technologies.

Asia-Pacific Leads Manufacturing and Commercialization

Asia-Pacific accounts for approximately 53% of global flexible solar cells demand. The region benefits from its established photovoltaic manufacturing base, extensive electronics industry, and increasing investment in perovskite and thin-film technologies.

China is a major contributor because of its large solar manufacturing ecosystem and growing investment in flexible perovskite production. Japan is also supporting commercialization through government-backed research and deployment programs, while India is developing domestic capabilities in emerging photovoltaic technologies.

The regional ecosystem combines manufacturing capacity, research institutions, renewable-energy demand, and government support, creating conditions for continued development of flexible solar products.

Material Supply Creates a Strategic Challenge

The expansion of CIGS technology also creates supply-chain considerations because indium is a critical material used in the cell structure. Concentrated global production and changing export policies can create uncertainty for manufacturers.

This is encouraging interest in alternative sourcing, material efficiency, recycling, and recovery from end-of-life photovoltaic products. Circular approaches could become increasingly important as flexible solar-cell production scales and demand for critical materials increases.

Flexible Solar Moves Toward Specialized Energy Generation

The flexible solar cells industry is moving from niche photovoltaic applications toward a broader range of lightweight and adaptable energy-generation formats. CIGS currently leads the technology segment, while polymer substrates provide the flexibility needed for unconventional installations.

Building-integrated photovoltaics, portable electronics, transportation, aerospace, defense, and off-grid power are creating distinct application pathways. At the same time, roll-to-roll manufacturing and perovskite development are addressing the need for scalable production and new performance characteristics.

Overall, flexible solar cells are expanding the boundaries of photovoltaic deployment by allowing solar generation to be incorporated into surfaces and structures that conventional rigid modules cannot easily accommodate. Their future development will depend on manufacturing scalability, material availability, durability, efficiency, and the ability to demonstrate reliable performance across increasingly diverse applications.
