GROUND BREAKING REVOLUTION – ENTER HJT

In the dynamic realm of solar energy, technological advancements continuously shape the landscape, striving to redefine the standards of efficiency and sustainability. Among these innovations, HJT (Heterojunction with Intrinsic Thin-Layer) solar panel technology emerges as nothing short of revolutionary. Through a ground-breaking amalgamation of amorphous and crystalline silicon layers, HJT panels unveil a transformative approach to solar energy conversion. This revolutionary design not only propels the efficiency of solar cells to new heights, consistently achieving levels comparable to or surpassing other advanced technologies like Topcon, it also introduces a paradigm shift in versatility with bifacial capabilities. As we delve into the distinctive features of HJT a compelling narrative unfolds, signalling the dawn of a new era in solar photovoltaics.

Topcon and HJT (Heterojunction with Intrinsic Thin-Layer) are two distinct solar panel technologies, each with its own characteristics and advantages. Here's a differentiation between these technologies, along with the benefits of using HJT over the other:

Topcon technology does not rely on a specific crystal structure but is associated with advanced passivated contacts, reducing recombination losses, and enhancing energy conversion efficiency. It can be applied to various types of solar cells, including monocrystalline and multi-crystalline cells.

Topcon technology focuses on advanced passivated contacts, which reduce recombination losses and enhance energy conversion efficiency. The manufacturing process may involve adding amorphous silicon layers to the crystalline silicon wafers to achieve these contacts.

Some Topcon panels may incorporate a bifacial design to capture sunlight from both the front and rear sides, similar to HJT.

Topcon panels are less susceptible to LID, ensuring that their efficiency remains stable over time.

Topcon panels are highly efficient and can achieve efficiencies in the range of 22% to 24%, making them one of the most efficient commercially available solar technologies. Advanced passivated contacts and surface passivation contribute to their high efficiency.

Topcon panels have a low-temperature coefficient, maintaining efficiency even in high-temperature conditions.

Topcon technology can be applied to various types of solar cells, providing flexibility in panel design and form factors. It is adaptable to different solar cell types.

Topcon panels may be more expensive than traditional panels but offer high efficiency and LID resistance, making them cost-effective over time.

HJT solar panels have a heterojunction structure, which combines both amorphous and crystalline silicon layers. This structure is designed to enhance charge carrier separation and light absorption, contributing to excellent efficiency and light-trapping properties.

HJT technology starts with the formation of a heterojunction by combining amorphous and crystalline silicon layers on both sides of the silicon wafer. Front and rear contacts are applied to collect and conduct electricity, and the cells are encapsulated within a protective layer.

Many HJT panels are bifacial, capturing sunlight from both the front and rear sides, which enhances energy production, especially in environments with reflective surfaces.

HJT panels are also less susceptible to LID, maintaining stable efficiency and performance.

HJT panels are known for their high efficiency, typically achieving efficiencies similar to or even surpassing Topcon panels (22% to 24%). The heterojunction structure and light-trapping properties enhance efficiency.

HJT panels have a low-temperature coefficient, making them suitable for hot climates where some other solar technologies may see significant efficiency losses, making them suitable for high-temperature conditions.

HJT technology can also be applied to various solar cell types, offering flexibility in panel design. It is versatile and can be used with different types of solar cells.

HJT panels may be more expensive to manufacture than traditional panels but offer a compelling balance between efficiency and cost-effectiveness, making them competitive with other advanced technologies like Topcon.

HJT panels offer efficiency levels comparable to Topcon panels, making them highly efficient for energy generation.

HJT panels can capture sunlight from both sides, increasing energy yield in environments with reflective surfaces.

HJT panels are less susceptible to light-induced degradation and maintain efficiency at high temperatures, providing consistent performance over time.

HJT technology can be applied to various solar cell types, offering flexibility in panel design and form factors.

While HJT panels may be more expensive than traditional monocrystalline panels, they can be a cost-effective choice when compared to some other high-efficiency technologies, like Topcon.

The choice between these solar panel technologies depends on factors such as efficiency requirements, cost considerations, and environmental conditions while Topcon and HJT technologies offer advanced features, including high efficiency, resistance to LID, and low-temperature coefficients and a bifacial design in HJT panels in particular, provide a competitive balance between efficiency and cost-effectiveness, potentially outperforming traditional monocrystalline panels and being competitive with other advanced technologies like Topcon.
