LONGi accomplishes new world record for p-type solar cell efficiency
- LONGi has introduced a new world record conversion effectiveness of 26.12% for its p-type silicon heterojunction (HJT) cell.
The record, confirmed in testing accomplished by the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, was achieved on full-size (M6, 274.3 cm2) gallium-doped p-type monocrystalline wafers and also is the highest possible record for p-type cell efficiency to date, more confirming the feasibility of affordable HJT mass production innovation.
The cell performance is 0.65% more than that of 25.47% released previously this year, showing LONGi's ongoing commitment to driving industrial development through technological advancement. The LONGi R&D team has enhanced the crystal drawing process in action to raised need for efficiency signs for p-HJT wafers, such as resistivity and also lifespan.
The performance of the cell has actually been significantly improved in regards to short-circuit present (Isc), open-circuit voltage (Voc) and fill-factor (FF), with boosts of 1.06%, 0.3%, and also 1.1%, specifically, as a result of continuous growths in user interface passivation and also home window layer micro crystallisation processes. It needs to be noted that the development procedure is similar to that for an n-type cell, fully showing the innovation's versatility and also dependability.
As a world-leading solar innovation business, LONGi has a long-lasting record of providing higher worth to end users via constant technical development, combining the firm's leading placement in new solar cell technology. In 2021 alone, LONGi broke the world record for cell conversion effectiveness 7 times, with effectiveness for n-type TOPCon, p-type TOPCon and also n-type HJT cells getting to 25.21%, 25.19% and 26.30%, specifically.
