Description
Solopower CIGS Flexible Solar Cell 1.25W 7.5x3.75in Stainless Steel Raw Lot 10
This listing is for a pack of 10 Solopower CIGS (Copper Indium Gallium Selenide) flexible thin-film solar cells built on a stainless steel substrate. Each cell measures 7.5 x 3.75 inches and produces approximately 1.25 watts under ideal sunlight. The cells are sold raw and uncoated — they must be encapsulated before use in any outdoor or weather-exposed application.
Specifications & What's Included
- Technology: CIGS (Copper Indium Gallium Selenide) thin-film

- Width: 95.25 mm (3.75 in)
- Thickness: 0.253 mm (0.01 in)
- Polarity: top side = negative; bottom side = positive
- Surface: uncoated / raw — encapsulation required for outdoor or long-term use
- Can be cut and divided into smaller cells without shorting
- Quantity: 10 cells per lot
Applications
CIGS thin-film solar cells are used in DIY solar energy projects, research and development, educational demonstrations, flexible and lightweight photovoltaic applications, and solar charger prototyping. Unlike rigid crystalline silicon cells, the stainless steel substrate makes these cells bendable, which opens them up for curved-surface mounting, wearable electronics research, and integration into non-flat structures. Solopower was a San Jose-based thin-film solar manufacturer known for its roll-to-roll CIGS deposition process on stainless steel foil — a technology aimed at producing lightweight, flexible solar modules for building-integrated and portable applications. These raw cells are well suited to hobbyists, engineers, and researchers who need to build or test custom solar assemblies. Because they are uncoated, the builder is responsible for encapsulating the cells with a suitable laminate or potting compound before exposing them to moisture or UV.
These Solopower CIGS Flexible Stainless Steel Solar Cells are new old stock and unused. The cells are raw and uncoated as manufactured — no encapsulant has been applied. Each cell is in clean, undamaged condition with no bending, creasing, or surface defects visible. Please view our photos and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
