Optimization of Hydrogenated Amorphous Si Layer for Si Heterojunction Solar Cells

Crystalline silicon (c-Si) solar cells that are well-established technologies have already achieved a power conversion efficiency (PCE) as high as 26.7% by using the interdigitated-back-contacted (IBC) configuration. However, this efficiency is still limited by the spectral mismatch between t¬he absorption characteristics of c-Si and the AM 1.5...

Analysis of Transition Metal Oxides based Heterojunction Solar Cells with S-shaped J-V curves

The use of transition metal oxides for the selective carrier contact in the crystalline silicon solar cells technology is rising to interest for the excellent optoelectrical properties of these materials whose implementation, however, can result in lousy performing cells due to an S-shaped electrical characteristic. In this paper, we fabricated...

Contact Stack Evaluation for SHJ Solar Cells and Process Development of IBC-SHJ Solar Cells

Nowadays, silicon heterojunction (SHJ) solar cell is one of the most promising photovoltaic technologies thanks to the outstanding passivation quality from the a-Si:H layers. Together with the interdigitated-back-contacted (IBC) architecture, it enables the highest efficient, 26.7%, single junction c-Si solar cell. However, the mass production...
