The "166" in the product name represents the dimensions of the solar cell, indicating its size in millimeters. A larger solar cell size allows for a greater surface area, which in turn enables more sunlight to be captured and converted into electricity. With a larger area, the PERC 166-9BB Bifacial Solar Cell can generate more power, making it suitable for applications that require higher energy production.

The "9BB" designation refers to the busbar configuration of the solar cell. Busbars are conductive metal strips that collect and distribute the electrical current generated by the solar cell. The 9BB configuration features nine busbars strategically positioned on the front surface of the cell, which reduces resistance and improves current flow. This design minimizes power losses and increases the overall performance and efficiency of the solar cell.

One of the notable features of the PERC 166-9BB Bifacial Solar Cell is its bifacial capability. Bifacial solar cells have the ability to capture sunlight not only from the front surface but also from the rear surface. This is achieved by utilizing a transparent backsheet or glass with a high transmission coefficient, allowing light to pass through and reach the rear side of the cell. The rear surface of the cell then reflects and absorbs the incoming light, increasing the overall energy generation. This bifacial design significantly enhances the power output of the solar cell, making it more efficient in converting sunlight into electricity.

Furthermore, the bifacial capability of the PERC 166-9BB Solar Cell allows for various installation options. It can be mounted on rooftops, where the reflected light from the ground or nearby surfaces can be utilized to generate additional energy. Ground-mounted installations can also take advantage of the bifacial feature by capturing the light reflected from the ground, further increasing the overall power output. This flexibility in installation makes the PERC 166-9BB Bifacial Solar Cell a versatile and efficient solution for solar energy systems.

In conclusion, the PERC 166-9BB Bifacial Solar Cell combines advanced features such as PERC technology, a larger size, and a 9BB busbar configuration to deliver high efficiency and increased energy generation. With its bifacial capability, this solar cell captures sunlight from both the front and rear sides, maximizing power output and providing a more efficient use of available sunlight. Whether installed on rooftops or ground-mounted systems, the PERC 166-9BB Bifacial Solar Cell offers exceptional performance, making it an excellent choice for renewable energy projects.
