Photovoltaic cells are an important means to effectively use solar energy. Among many types of photovoltaic cells, monocrystalline silicon solar cell technology has established a significant advantage in the photovoltaic industry.

P-type monocrystalline silicon developed earlier, mainstream products have experienced the continuous development of BSF cells, PERC cells and double-sided PERC+ cells, and cell efficiency has gradually approached the bottleneck. In contrast, N-type silicon wafers have a longer minority carrier lifetime and smaller light-induced attenuation. It is recognized that the development of high-efficiency photovoltaic cells in the future will switch to N-Topcon, HJT and other N-type batteries.

Bluesun Solar believe that the HJT technology solar cell solar panel is mature and its efficiency is further improved compared with the existing PERC. Although the current equipment investment is high and the amount of silver paste is large, with the progress of domestic equipment and the advantages of large-scale, plus the modification of silver paste and copper electroplating After the breakthrough of the cost reduction program, the cost of large-scale mass production is expected to be reduced to a level acceptable to the market. At present, the 1GW investment cost of domestic equipment has been reduced to about 450 million yuan, and there is room for further reduction in cost.

In addition, HJT's high bifacial ratio, low attenuation, low temperature coefficient and other technical characteristics make the full life cycle power generation may be 7% to 15% higher than PERC. Therefore, although the initial component investment is high, the LCOE may not be high.

In terms of efficiency, HJT may have more room for improvement relative to Topcon, and due to the existence of the TCO conductive layer, it is easier to form a laminated battery with perovskite, leading the direction of technological development.

Recently, Bluesun Solar produced most efficient 570W HJT shingled solar panel. More information,  please don't hesitate to send us inquiry.
