High-efficiency half-chip battery technology with low internal loss will have unique advantages in large-scale applications. It is undoubtedly an efficient solution for mass production and cost-effective, and is the best solution to meet both cost and power generation and attenuation performance. Half-cell technology is a technique in which a standard-size cell (156mm x 156mm) laser is cut into two pieces (156x78mm) for joining and cutting.

The cell of the entire assembly is then divided into two groups, each group containing 60 half-cell cells connected in series. A complete 120-piece component is formed, which reduces the current through each main gate to 1/2, and reduces the internal loss to 1/4 of the entire battery, thereby increasing component power.

This technology has the following characteristics:First, the efficiency of a half-piece photovoltaic module with the same efficiency is significantly higher than that of a conventional full-chip component. This is mainly due to the reduction of the series resistance of the half-chip components and the improvement of the fill factor FF. At the same time, the internal resistance of the component is reduced, so that the temperature during power generation is lower than that of the conventional component, thereby further improving the power generation capability of the component.

Second, the half-chip assembly can reduce the power generation loss caused by the occlusion, and can significantly increase the power generation of the assembly in the morning and evening and the assembly along the ash and snow, and improve the economic efficiency of the power station.

Third, compared with other new technologies, the half-chip technology is the most mature and the easiest to achieve rapid mass production, while the additional cost is not much.

The technical principle of the half piece assemblyAs mentioned above, the half-cell is obtained after the half-cut of the standard cell. Therefore, the internal current is reduced by half. As the current decreases, the power loss inside the battery decreases. The power loss is usually proportional to the square of the current, so the power loss of the entire component is reduced by a factor of four (Ploss = RI2, where R is the resistance, I is the current) to reduce the power loss of the half-chip, which can make it more Large fill factors, higher conversion efficiencies, and greater power generation, especially in high-radiation environments. The component has a large fill factor, meaning that its internal series resistance is small and its internal current loss is small.In addition, the new design improves the electrical performance of the cell under occlusion or morning and evening conditions compared to standard components. For example, if the standard components are mounted in the portrait orientation and the bottom is shaded, the bypass component will shut down the entire string of cells, resulting in zero output power for the entire assembly. The half-chip assembly benefits from the layout of the two-part battery string set, ensuring that its output power remains at least 50% under the same conditions.

JDSOLAR's high-efficiency half-chip assembly (HC) series uses full-automatic split and transmission, and can be applied to single-crystal, polycrystalline, single-crystal PERC, and polycrystalline PERC components on a large scale, allowing for additional cost increases. The component power is 5-10 watts higher than conventional components of the same version. JDSOLAR60 polycrystalline half-chip components can be mass-produced to 290W in mainstream power, 305W in single crystal, and up to 330W in single-chip PERC. With half the effort, the half-chip technology will occupy a mainstream position in the future civil and small-sized industrial and commercial roof systems with its high cost performance.The JDSOLAR half-chip battery pack has the following features:

(1) The battery chip is divided into two, the main gate current is halved, the current loss of the whole component is reduced to 1/4 of the original, and the output power is about 5-10W higher than that of the same type of whole battery assembly;

(2) The hot spot temperature of the half-chip battery assembly is lower than the temperature of the same-type full-piece battery assembly by about 25 ° C, which can effectively reduce the hot spot effect of the component;

(3) Half-chip battery components meet the 1500V system voltage design requirements, which can reduce the system-side cost by about 10%;

(4) When there is ash or snow on the occlusion and the lower edge, the loss of power generation caused by occlusion is effectively reduced;(5) Reduce the first year and the average photoinduced attenuation;

(6) 100% PIDFree.

How customers benefit from JDSOLAR's half-cell battery technology

JDSOLAR's polycrystalline half-chip assembly can be compared with conventional single-crystal components, while single-crystal half-chip components compete with conventional single-crystal PERC components in terms of conversion efficiency and overall performance. This means that customers have a new, more cost-effective option while ensuring component power. The JDSOLAR half-chip component is one of the most competitive products in the commercial market today.

In addition, the multi-watt boost of the JDSOLAR half-chip component per unit area power output allows the component to jump at the power bin level, resulting in better economic benefits for the customer in the same mounting area compared to installing a conventional component system.
