LONGi claims brand-new p-type heterojunction cell efficiency record of 25.47%.
- Solar maker LONGi has laid claim to a brand-new cell effectiveness record for a gallium-doped p-type heterojunction PV cell.
The 'Solar Module Super League' (SMSL) participant claimed it had actually recorded a cell conversion performance of 25.47% utilizing an M6 (274.3 cm2) full-size cell, created using automation procedures as well as monocrystalline silicon wafers.
The effectiveness was validated in testing carried out by the Institute for Solar Energy Research in Hamelin (ISFH).
LONGi claimed the business's R&D team developed the p-type wafer processing remedy for heterojunction cells as well as incorporated it with a user interface passivation technology to attain an open circuit voltage (Voc) of 747.6 mV.
Moreover, LONGi stated that it did not regard handling techniques used in this record to have been totally optimised, recommending that the conversion efficiency could be pressed even more.
