PV Ribbon is also called a tinned copper ribbon or tinned copper strip. It is an important part of photovoltaic modules and is used for connections in photovoltaic cell packages. And it will lead out the electrical energy converted from light energy on the silicon chip and deliver it to electrical equipment. It plays an important role in conducting electricity and gathering electricity. To increase the output voltage and power of photovoltaic modules. Photovoltaic cells connected by PV Ribbon are packaged in EVA film, photovoltaic glass, back film, frame, and other materials to form a photovoltaic module. We can use photovoltaic modules directly in the construction of photovoltaic power generation systems.
Importance of PV ribbon
The quality of PV Ribbon is related to the power transmission efficiency and service life of photovoltaic modules. The appearance size, mechanical properties, surface structure, resistivity, and other performance indicators of PV Ribbon are important factors that affect the efficiency of photovoltaic power generation, the fragmentation rate of photovoltaic cells, and the long-term reliability and durability of photovoltaic modules. High-quality, high-tech PV Ribbons can not only greatly improve power generation efficiency. Moreover, it can also reduce the fragmentation rate of photovoltaic cells and ensure the long-term stable operation of photovoltaic modules. It is an important way for downstream photovoltaic power generation enterprises to reduce costs and increase efficiency.
Classification of PV Ribbon
There are various types of PV ribbons to meet different characteristics. According to the direction of the product application. We can divide it into PV Interconnector and PV Bussing Ribbon.
PV Interconnector is a tin-coated ribbon. We can use it to connect PV cells to collect and transmit the current of PV cells. It connects to the front and back grid lines of the cells. And also, it connects the positive and negative electrodes of the neighboring cells to form a series circuit.
Usually, we use PV Bussing Ribbon to connect PV cell strings and junction boxes. It is a tin-coated ribbon that transfers the current from the PV strings and connects the strings together to realize a complete current path. For conventional PV modules, the consumption ratio of the PV Interconnector and PV Bussing Ribbon is about 4:1. For multigrid modules, the consumption ratio of the PV Interconnector and PV Bussing Ribbon is about 5:1.
According to the performance and application field of PV Ribbon. PV Interconnector mainly includes conventional PV Interconnector, MBB ribbon, low-temperature ribbon, low-resistance ribbon, etc. PV Bussing Ribbon mainly includes conventional PV Bussing Ribbon, perforated ribbons, black ribbons, bending ribbons, etc.
Policies for the photovoltaic industry
From the perspective of downstream industrial policy, national policies will strongly support the photovoltaic industry. Data from the National Energy Administration shows that as of the end of 2021, China’s cumulative installed capacity of photovoltaic power generation reached 307 million dry watts, and the new installed capacity reached 0.55 billion kilowatts in 2021. According to the Implementation Program on Promoting the High-Quality Development of New Energy in the New Era issued by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) at the end of May 2022, it is aimed at anchoring the goal that China’s total installed capacity of wind and solar power generation will reach more than 1.2 billion dry watts in 2030. Accelerate the construction of a clean, low-carbon, safe, and efficient energy system.
Promote the application of new energy in industry and construction. By 2025, the roof photovoltaic coverage rate of new buildings in public institutions strive to reach 50%.2022 The “14th Five-Year” Renewable Energy Development Plan, released in early June, re-emphasized the photovoltaic industry in different regions, scenarios of the construction and use. The author believes that, from the national level, the state will support the photovoltaic industry to be a sunrise industry. And in the next ten years, the state will vigorously enhance the scale of installed photovoltaic capacity to promote the development of the industry and reshape the energy system.
Renewable energy in the newly installed capacity
From the perspective of downstream industry, with the promotion of “carbon neutral” in many countries. The development of renewable energy represented by photovoltaics has become a global consensus. The proportion of renewable energy in the power structure continues to improve and can promote the rapid growth of PV installed capacity. 2020 global PV power generation accounted for only 3.1% of the total power generation, penetration rate to enhance the space is still big. 2021 PV power generation accounted for 39% of the share of renewable energy power generation of newly installed capacity. Renewable energy in the newly installed capacity accounted for the highest. It reflects the potential for the development of the photovoltaic industry.
Future of the PV ribbon industry
Currently, the PV ribbon industry is highly concentrated and dominated by Chinese private enterprises. Under the background of “carbon neutral” PV installed demand is expanding rapidly. We expect PV ribbon will reach 174,800 tons market size in 2026. PV ribbon, as a sub-segment of the solar PV industry, has the characteristics of “small industry, big market”. PV ribbon, as a niche industry in the solar photovoltaic industry, has a “small industry, big market” characteristic. In the large industry under the background of high boom brought about by the market demand for space. It can attract a number of PV ribbon production enterprises to enter the field.
