Conversion efficiency of 26.6% achieved by heterojunction back contact (HJ-IBC) solar cell. This result was obtained using CZ silicon wafer. 0.3% absolute improvement in efficiency from the previous record is mainly driven by low series resistance.
This study deals with the development and optimization of Interdigitated Back Contact (IBC) Silicon Heterojunction (Si-HJ) solar cells based on n-type crystalline silicon (c-Si) substrates. Both one-dimensional (1D) and 2D aspects of IBC Si-HJ cells are explored in this work.
It is shown that the defined reduction efficiency rate of an HJ-IBC silicon solar cell is lower than the reduction efficiency rate of conventional silicon solar, suggesting a better performance in the outdoor condition of the HJ-IBC solar cells.
As further development from 26.6%, pseudo FF of 86.6% is obtained from SunsV OC of the newly developed HJ-IBC cell. We have developed heterojunction interdigitated back contact solar cell with conversion efficiency of 26.6% (designated area: 180 cm 2) independently confirmed by Fraunhofer Institute for Solar Energysystem Callab.
Introduction Conventional IBC solar cells involve c-Si doped regions (homojunction technology) and reach experimentally more than 24% efficiency . An alternative approach for IBC devices fabrication has been proposed in 2007 by introducing the Silicon Heterojunction (Si-HJ) technology.
Architecture The 26.6% HJ-IBC solar cell was fabricated using n-type Czochralski crystalline Si (c-Si) 6 in. wafer with a size of 243 cm 2, a thickness of 200 µm (wafer thickness after cell fabrication), and a resistivity of ~ 7 Ω cm. The front wafer surface was textured by anisotropic etching in order to minimize the light reflection.
