125mm Flexible Solar Cells – 23% High-Efficiency 3.7 W Monocrystalline Solar Cells for University Research, DIY Lab Prototypes, Full & Pre-Cut 1/2 1/3 1/6 Segments Options (20, 1/3 Part-Middle)

Unlock next-generation solar R&D with ultra-light flexible solar cells that pack 23 % efficiency and 3.7 W output into a 125 mm wafer. Manufactured from high-purity, rear-contact monocrystalline solar cells, each piece maximizes active surface area to deliver dense, repeatable power for university photovoltaics labs, physics demonstrations and renewable-energy curricula. /n Available in full size or factory-cut 1/2, 1/3, 1/6 segments, the cells slot seamlessly into breadboard experiments, micro-grid prototypes and custom curved modules—no laser cutter needed. The copper back-plane flexes without cracking, and a tin corrosion barrier plus lead-free construction keep long-term measurements stable under outdoor, salt-spray or humidity cycling. /n Important Note on Pre-Cut Options: For 1/3 and 1/6 cuts, we ship randomly selected middle sections of the cell. End sections are not available by default. For specific cutting preferences, contact our customer support before placing your order.

• 【Lab-grade efficiency for accurate data】23 % conversion and 3.7 W per 125 × 125 mm N-type monocrystalline solar cells supply high power density for photovoltaic experiments and prototype modules.
• 【Multiple precision cut sizes】Choose full, 1/2, 1/3 or 1/6 pre-cut segments to quickly tailor flexible solar arrays for capstone projects, cube-sat testbeds, IoT sensors or portable power studies.
• 【Robust back-contact architecture】Copper foundation with no front bus-bars bends up to 30 ° without micro-fractures, while a tin barrier shields conductors from corrosion for long-term lab reliability.
• 【RoHS lead-free, student-friendly assembly】Pre-tinned pads enable low-temperature soldering or conductive epoxy bonding, perfect for makerspaces, engineering courses, STEM kits and science-fair builds.
• 【Versatile academic applications】Integrate these flexible solar cells into perovskite tandem trials, indoor light-harvesting research, wearable electronics, drone wings or off-grid environmental monitoring.
