With the increasingly urgent need for renewable energy, back contact solar cell are becoming the focal point of the photovoltaic industry as the next generation of solar technology. In the rise of this innovative technology, Raytron’s solar tabbing wire is becoming an integral part of BC cell manufacturing with its superior connectivity and technical support.
The Rise of BC Photovoltaic Cells
back contact solar cell are leading the evolution of photovoltaic technology with their back-contact design solution. Its front side is made of SiNx/SiOx double-layer reverse-reduced passivation film, which eliminates the traditional metal grid lines and cleverly arranges the emitters and backfields as well as the positive and negative electrodes of the corresponding areas on the back side of the cell. This unique design maximises the photoelectric conversion efficiency and has the advantage of higher theoretical conversion efficiency than other technologies.
Industry giants such as LONGi Green Energy and Aixu have high hopes for BC technology, believing that it is expected to become the mainstream technology route in the PV industry in the next 5-6 years. However, the manufacturing process of back contact solar cell is relatively complex and the cost of equipment is high, so industrialisation is still in its infancy and requires continuous technological innovation and market promotion.
Raytron solar tabbing wire: the key to connecting back contact solar cell
In the manufacturing process of back contact solar cell, soldering tape is one of the core components for connecting the cells, and Raytron’s solar tabbing wire plays a key role in back contact solar cell through its excellent technical performance:
Efficient connection performance: The backside design of back contact solar cell requires precise alignment of the positive and negative electrodes and emitters on the cell, Raytron solar tabbing wire provides efficient connection to ensure stable current transfer between the cells, reducing series resistance and optimising the efficiency of electron transfer.
Adaptation to complex structures: The unique structure of back contact solar cell places higher demands on the adaptability of the welding tape, and Raytron solar tabbing wire ensures good stability and reliability under complex structures through advanced processes and material selection.
Improve overall performance: solar tabbing wire is directly related to the performance of the entire PV system. back contact solar cell with Raytron solar tabbing wire are able to convert solar energy more efficiently, which in turn improves the power generation efficiency of the overall system and contributes to the development of clean energy.
Technology upgrade and innovation: Raytron, as a leader in the field of solar tabbing wire, is constantly making technological innovations. Its unremitting efforts in material, process and design have enabled it to produce welding tapes that better meet the special needs of BC batteries, contributing to the technological upgrading of the industry.
Looking to the Future
BC photovoltaic cells, together with Raytron solar tabbing wire, constitute the golden combination for the future of clean energy. As BC technology continues to mature and market demand expands, this combination will occupy an increasingly important position in the PV industry, and Raytron’s solar tabbing wire, as a powerful assistant in BC cell manufacturing, will contribute to more possibilities for global sustainable development under the impetus of clean energy technology.
