Chinese module manufacturer Longi unveiled its new module with HIBC cells at the SNEC 2025 trade fair last week. According to the company, this is the first time a standard module size of 2,382 by 1,134 millimetres has achieved an output of over 700 watts. The module has an efficiency of 25.9 per cent and a power density of over 259 watts per square metre. The high efficiency is achieved, among other things, by a very dense cell coverage, which according to Longi accounts for 95.1 percent of the module area.
»Another great value brought by HIBC technology is to comprehensively lead the efficiency of mass-produced photovoltaic modules into the “25 per cent+Era«. As we all know, in the PERC era, the module efficiency was 22 per cent+, TOPCon brought 23 per cent+, and the gate of 24 per cent+ module mass production efficiency was opened by BC« the company said in a statement.
In April, Longi announced a record efficiency of 27.81 percent for a HIBC cell, certified by the Institute for Solar Energy Research Hameln (ISFH).
With its »Hybrid Interdigitated Back-Contact« technology, Longi combines heterojunction technology with back-side contacting. According to Longi, developing the HIBC technology took »less than three years«.
