10mm High-Efficiency Cells
Utilizing HJT 210mm solar cells with high efficiency, its Transparent Conductive Oxide (TCO) film effectively passivates the interface defects of crystalline silicon and doped amorphous silicon, resulting in a photoelectric conversion efficiency of 25%. HJT solar panels are designed with an increased number of finer busbars, which effectively reduces shadowing caused by busbars and shortens the distance for current transmission.
High Bifacial Rate
HJT solar panel feature a unique design with symmetrical structures on both front and back sides, paired with mesh plates. This configuration significantly boosts their bifacial electricity generation capabilities. Remarkably, these cells achieve over 95% power generation efficiency on the rear side, marking a substantial improvement in overall energy production.
Excellent Low-Light Performance
HJT solar panel integrate i-a-SiH thin films between crystalline silicon and doped amorphous silicon. The undoped hydrogenated amorphous silicon layer (i-a-Si:H) serves to passivate defects present on the crystalline silicon surface. This passivation process reduces the recombination of charge carriers at the interface, resulting in an increased open-circuit voltage (Voc), leading to high open-circuit voltage (750mV).
Low Temperature Coefficient
In the warm and sunny conditions typical of European summers, Heterojunction (HJT) solar panels stand out as the superior choice. Their low temperature coefficient of -0.24%/°C, compared to PERC and TOPCon cells, ensures stable and efficient power generation, even in higher temperatures.
Low Degradation
HJT cells eliminate the possibility of electronic issues on the cell surface, preventing Light-Induced Degradation (LID) and Light and Elevated Temperature-Induced Degradation (LeTID) effects. The TCO film layer, endowed with conductive properties, prevents the generation of surface polarization, structurally mitigating the risk of Potential-Induced Degradation (PID) decay.
High Reliability
The HJT solar panel is equipped with weather-resistant, corrosion-resistant, and wear-resistant double-sided glass and POE encapsulation, providing a 30-year guarantee for both product and performance. The low-temperature process and no-cut solar cells technology make the cells less damaged, highly flexible, less occurrence of microcracks, and easy to transport and install.
Crystalline silicon is regularly used to create standard homojunction solar cells, seen in conventional panels. There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar panel since it has a higher purity and therefore more efficient.
Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells. While a-Si on itself has density defects, applying a hydrogenating process solves them, creating hydrogenated amorphous silicon (a-Si:H), which is easier to dope and has a wider bandgap, making it better for creating HJT solar panel.
Indium Tin Oxide is the preferred material for the transparent conductive oxide (TCO) layer of the heterojunction solar cell, but researchers are investigating using indium-free materials that will reduce costs for this layer. The reflectivity and conductivity properties of ITO make it a better contact and external layer for the HJT solar cell.
Manufacturing Process of HJT Solar Panel
Cleaning and Texturing
This step removes impurities from the N-type silicon substrate and creates a textured surface that traps light and reduces reflection.
Deposition of Amorphous Silicon Films
Using PECVD (Plasma Enhanced Chemical Vapor Deposition), the cell’s surfaces are coated with intrinsic and doped amorphous silicon layers. These layers passivate the surface, reducing defects and increasing efficiency.
Deposition of the TCO Layer
The TCO layer is applied using sputtering or RPD (Reactive Plasma Deposition). This layer collects electrical carriers and transports them to the cell’s electrodes. The TCO layer also enhances light absorption and reduces reflection.
Screen Printing and Curing
Metal electrodes are printed onto the cell and then cured at low temperatures. This step is simpler and less energy-intensive compared to high-temperature processes used in other solar cell types.
