CIGS Technology
CIGS EXPLAINED
What Is CIGS?
CIGS stands for Copper Indium Gallium Selenide, a semiconductor material capable of converting sunlight directly into electrical energy.
In a CIGS solar cell, the active photovoltaic layer is extremely thin compared with the silicon wafers used in conventional crystalline solar modules.
Because this photovoltaic material can be deposited onto an ultra-thin flexible substrate, the finished solar cell can bend and conform to surfaces that would be difficult for conventional rigid glass solar panels.
A DIFFERENT FORM OF SOLAR
Solar technology no longer has to be built around
heavy glass and rigid frames.
Ultra-Thin
The photovoltaic stack can be produced at an extremely small total thickness, enabling lightweight solar construction.
Flexible
Thin-film cells can bend, curve and adapt to surfaces that are unsuitable for conventional rigid modules.
Low-Light Performance
CIGS technology maintains useful output across changing illumination and cloudy conditions.
Built for Mobility
Lightweight and flexible construction makes CIGS particularly suitable for portable and mobile applications.
ULTRA-THIN ARCHITECTURE
Inside a Flexible CIGS Solar Cell
A flexible CIGS cell is constructed from multiple microscopic functional layers deposited onto a thin flexible substrate. Each layer performs a specific optical or electrical function while the complete photovoltaic structure remains extremely thin.

FROM MATERIAL TO ENERGY
From Thin-Film Materials to Flexible Solar Modules
The flexibility of CIGS begins at the material level. Advanced semiconductor layers are combined with an ultra-thin metallic substrate and transformed into lightweight photovoltaic cells and flexible modules.
REAL-WORLD PERFORMANCE
Solar Power Beyond Perfect Sunlight
Laboratory efficiency is only one part of solar performance. In the real world, solar modules experience changing temperatures, partial shading, clouds, varying solar angles and different levels of illumination throughout the day.
Long-Term Stability
CIGS technology has demonstrated stable photovoltaic performance across long-term real-world operation.
Temperature Performance
A favorable temperature coefficient helps reduce power loss as panel temperature increases.
Partial Shading
Flexible thin-film cell architecture can retain useful output when part of the module is shaded.
Changing Light
Broad-spectrum light absorption supports useful generation during mornings, evenings and cloudy weather.
DIFFERENT BY DESIGN
Why Make Solar Flexible?
Because many of the places that need energy were never designed around a rigid rectangular panel.
ROLL
Compact transportation and easier storage.
BEND
Adapt to curved, irregular and unconventional surfaces.
MOVE
Bring solar energy to mobile and portable applications.
A NEW WAY TO THINK ABOUT SOLAR
Conventional solar asks:
“Where can we install a panel?”
Flexible solar asks: “Where could we generate energy?”
“Where can we install a panel?”
Flexible solar asks: “Where could we generate energy?”
SOLAR WITHOUT LIMITS
Where Can Flexible CIGS Go?
Flexible photovoltaics can bring solar generation into products and environments where weight, shape and mobility matter.
Outdoor & Camping
Rollable solar power for campsites, expeditions and remote environments.
RV & Overlanding
Flexible photovoltaic solutions for mobile energy systems and vehicle surfaces.
Marine Applications

Special Applications
Flexible energy for products where traditional panels cannot easily fit.
Aerospace & Advanced Mobility
Lightweight photovoltaic technologies for weight-sensitive emerging applications.
CUSTOM CIGS SOLUTIONS
Your Application May Need a Different Solar Panel.
Flexible photovoltaic technology creates opportunities to design solar around the application instead of forcing the application to fit a standard panel.
Depending on the project, AURICU can discuss custom dimensions, electrical output, connector configurations, mounting requirements and specialized system integration.
If your requirement is more technical, our support team can connect you directly with our engineering team.
