Highest Bifacial Ratio

95%+ Higher Bifaciality

Heterojunction (HJT) cells have a natural bifacial symmetrical structure that makes them ideal for use in various application scenarios. With a bifaciality of more than 95%, HJT cells have a superior ability to capture as much sunlight as possible, providing an increased power output. This enhanced energy output makes them an excellent choice for those who want to get the most out of their solar energy systems. The bifaciality of HJT cells is extremely important because it ensures that the cells can harvest energy from both sides, maximizing the amount of sunlight that is converted into electricity. With this feature and high-quality construction, HJT cells are a reliable and efficient choice for those looking to invest in sustainable energy sources.

Best Temperature Coefficient in market

-0.26%/C Extreme low-temperature coefficient

Heterojunction with Intrinsic Thin-layer (HJT) solar cells are an advanced alternative to conventional cells. They exhibit a lower temperature coefficient (-0.26%/°C), resulting in a more stable power output even when exposed to high temperature and high irradiation areas. When compared to other solar cell technologies, such as PERC and Topcon, HJT solar cells demonstrate a higher daily power output of up to 6% and 3% respectively when using modules with the same power. These features make HJT solar cells an excellent choice for applications where consistent and high-performance power output is vital, particularly in remote locations with extreme weather conditions and residential and commercial PV installations, where maximum energy yield is desired. In general, HJT solar cells provide a multitude of advantages over traditional solar cells, making them a valuable investment for any modern energy system.

Degradation rate of hht solar cell and panel

1% first year and 0.28% each year. Lower degradation rate.

HJT solar cells are a fantastic innovation in the world of solar power. These cells are constructed with N-type silicon wafers, which are known for their incredible durability and resistance to what is known as the Light-Induced Degradation (LID) effect. This means that HJT cells are perfect for long-term use and will continue to provide reliable energy for many years to come.

In addition to their durable construction, HJT solar cells also feature anti-reflection and protective layers, as well as TCO film that is conductive. This not only adds to their longevity, but also helps to prevent polarization of the charge on the surface of the cell, which can lead to the undesirable phenomenon of Potential Induced Degradation (PID).

So, whether you are an individual looking to power your home with renewable energy, or a business looking to reduce your carbon footprint, HJT solar cells are a smart choice that will provide you with clean, reliable, and long-lasting energy for years to come.

thinner wafers and combination with perovskite

80μm Thinner Wafers

The manufacturing process of HJT solar cells is simplified
and at a lower temperature than conventional solar cells. It’s a natural bifacial symmetrical structure that reduces the mechanical stress in cell production, enabling thinner wafers (≤120μm). Combining SMBB technology and 0 Busbar technology, the conversion efficiency can be further improved and costs reduced. With the mass production of N-type silicon wafers, the cost advantage of thin wafers will be more prominent.

Combination with Future Technology HJT + Perovskite

Due to their structure, HJT cells are very suitable to use as substrates to stack with perovskite cells. The combination of these two technologies is considered to be the most promising. Simulations show that the conversion efficiency of the laminated cells can reach more than 35%.
