125mm Back-Contact IBC Mono Solar Cell, 3.7W, Full / Cut Options

5-Inch IBC Back-Contact Solar Cells – Full & Custom Cut

⚙️ High-Efficiency Solar Cells for Precision Applications

We provide IBC solar cells (Me3 bin, 24.0–24.4% efficiency), available in:

🔹 Full Cell

🔹 Half-Cut

🔹 1/3 Cut

🔹 1/6 Cut

🔹 Center Strip (middle only, edges trimmed)

For center strip options, one center strip is produced from each source cell. Only the selected center strips are supplied; the remaining side pieces are not included.

All cells are cut using laser + mechanical precision. Suitable for research labs, universities, product developers, and solar tinkerers.

Important Testing Disclaimer

Please note:

• All product specifications listed (voltage, current, power) are based on the published Me3 bin ranges under STC conditions.
• However, our cutting process, measurement tools, and test protocols follow our own internal standards, not SunPower’s original lab calibration.
• Due to the nature of manual cutting and edge loss, actual performance may vary slightly from theoretical values.

⚠️ We do not guarantee that your DIY project or custom test results will match our provided data. Variations may occur due to soldering methods, ambient conditions, contact quality, or module design.

We will do our best to share technical advice and data sheets upon request, but:

• cannot be held responsible for final output, performance deviation, or unexpected behaviors during integration.
• This product is intended for research, prototyping, and educational use.

For professional module integration, we strongly recommend independent testing under your own system conditions

Buyer questions

Can I solder these cells by hand?

The cells are ready for tabbing wire or conductive adhesive, and pre-tabbed or solder-ready options can be requested as a custom order. Results depend on your soldering method, contact quality and test setup, so test on a sample build first.

How many cut cells do I need in series for about 5 V?

Every cut size is listed at a typical 0.625 V (Vmp, STC), so 8 cells in series give about 5.0 V typical (8 x 0.625 V). Current is set by the cut size: 3.03 A for a half-cut down to 1.01 A for a one-sixth cut.

Will my own results match the listed numbers?

Not guaranteed. The listed values come from published Me3 bin ranges under STC, and actual performance may vary slightly after cutting. Test data is included with each order; cells go through EL and IV curve testing.

Are these official SunPower-branded cells?

No. The cells are de-branded, and LinkSolar is not affiliated with SunPower/Maxeon. LinkSolar provides the processing and cutting.

LinkSolar supplies solar cells to B2B buyers; ships from China.
