NINGBO, China, Oct. 24, 2022 \/PRNewswire\/ — With the rapid development of PV technology from p-type to n-type, the difference in power generation of different cell technology products are drawing more and more attention. Nowadays the mainstream cell technologies are PERC, TOPCon and HJT. Each of them has its own advantages and disadvantages, but the comparative research on power generation is still lack of systematic whole-life cycle comparison based on the perspective of global application scenarios.<\/span><\/p>\n<\/div>\n

To this end, the core parameters of above mentioned three technologies are collected and the power generation of utility-scale power plants with these three different cell technology panels over a 25-year life cycle in 21 typical countries and regions with different climatic environments around the world are measured by Risen Energy Co., Ltd to create a comparison map of global power generation gains.<\/p>\n

Globally, HJT technology products have higher power generation, which is 4.37%-6.54% higher than PERC and 1.25%-3.33% higher than TOPCon. and its power generation performance is more outstanding especially in high temperature regions (e.g. the Middle East, Australia and the southern US), with \u00a06%+ gain compared to PERC and 3%+ gain compared to TOPCon. As shown in Figure 1.1.<\/p>\n

II. Technical analysis of modules<\/b><\/p>\n

Based on the characteristics of the modules, the power generation gap between different cell technologies in each region on the map is mainly caused by three factors: temperature coefficient, bifacial factor and power degradation, which is why the HJT modules can deliver higher power generation gains and more stable power yield for the PV system with its extremely stable temperature coefficient, higher bifacial factor and higher power retention.<\/p>\n

2.1\u00a0<\/b>Extremely stable temperature coefficient<\/b><\/p>\n

Compared to the power temperature coefficient of -0.35%\/\u00b0C for PERC and -0.32%\/\u00b0C for TOPCon, HJT modules have a more stable power temperature coefficient of -0.24%\/\u00b0C, which means the HJT modules are of lower power degradation compared to PERC and TOPCon modules as the module operating temperature rises, thus reducing the power generation loss, and this power generation gain advantage will be especially in case of high operating environment temperature, as shown in Figure 2.1.<\/p>\n
