SilexSolar Photovoltaic Cells

The SLX Cell 125

The SilexSolar SLX Cell 125 series is a high power mono-crystalline solar cell that incorporates an anti-reflective coating to generate more energy (kWh per kW). The cell has undergone individual testing and is laser scribed on the rear, identifying its power band and batch number.

High-efficiency single crystal solar cells using the latest silicon nitride process technology

Highest Quality & Performance

• All cells are 100% visually inspected for cosmetic defects, chips, bowing, uneven thickness and microcracks
• All cells are 100% electronically tested, packed and identified into efficiency and current groups with high accuracy
• Advanced gettering and passivation process coupled with aluminium BSF (Back Surface Field) produce very high performance
• High-grade silver and silver/aluminium pastes produce cell contacts of high bonding strength and long-term reliability
• Advanced screen-printing techniques ensure high precision electrical grid contacts.

NOTE:

• Above strictly relates to cell performance, not PV panel performance
• Cell Efficiency and Maximum Power are for un-encapsulated cells measured at the cell tester
• Cell Efficiency and Maximum Power are the distribution average while individual cells may vary
• The cell electrical performance is measured with:
  • A Class A Solar simulator (as per IEC 60904-9) at STC (Standard Test Condition) defined as illumination of 1000 W/m2, at spectral distribution of AM1.5, and cell temperature of 25ºC
  • Separate current and voltage (Kelvin) probes at multiple points on the solar cell front contact area.

SilexSolar cell performance

Physical Characteristics

Solderability

Cells are capable of having lead-free plated copper interconnect ribbon, soldered to the front and rear of the cell.

Important

The encapsulate power of cells in a finished panel will be determined by soldering technique, dimensions and quality of interconnect ribbon, encapsulation materials and glass type. Encapsulation losses of up to 3% may be typical, after allowing for interconnect and encapsulation materials losses.

Reliability

SilexSolar crystalline silicon solar cells have been designed and manufactured for reliability and performance in all environments when used and manufactured in accordance with SilexSolar practices and recommendations.

Long-term reliability of SilexSolar cells are entirely dependent on the quality of cell interconnection materials, soldering technique, together with the encapsulation materials (EVA, glass and polyester quality etc.) and workmanship used to manufacture the panels.

SilexSolar Solar cannot accept liability for cell breakage during third party panel manufacture nor the long-term reliability of the panel made with materials and processes outside the control of SilexSolar.

Cell manufacturing process

SilexSolar's “high-performance” solar cells which are carefully tested and inspected at every stage of the manufacturing process. Thus SilexSolar cells are of the highest quality and electrical performance.

International Certification

SilexSolar have been internationally certified by TÜV Rheinland Japan Ltd and has also obtained CE marking certification for sales to the European Economic Area (EEA).
