Learn MoreIntense illumination treatments on silicon heterojunction cells (SHJ) have recently gained interest to improve the final cell efficiency and are now being implemented into cell manufacturing tools. However, additional efforts are still required to clarify the robustness of such approach.
Introduction and context The conversion efficiency of amorphous/crystalline silicon heterojunction (SHJ) solar cells and modules can be improved under prolonged (several hours) and mild (typically <1 sun) light soaking (LS) [1 ].
We investigated the effect of intense illumination treatments on silicon heterojunction modules. The developed treatments showed efficiency gains up to +0.30 %abs, stemming from improvements in V oc and FF, and slight gains in I sc. The stability of the gains was assessed over 2 months of dark storage.
Alternatively, higher-mobility materials compared to ITO are successfully implemented in Si heterojunctions, following the success of hydrogen-doped indium oxide [118, 119]. These typically rely similarly on solid-phase crystallization of an amorphous doped indium-oxide film.
HJT cell has a high bifaciality factor of 92%, making HJT deliver a great performance when designed as a bifacial module. This technology is becoming more popular for utility-scale applications, which seek to take advantage of the albedo resource.
The large gains following UV tests also suggest more room for improvement of the fast module illumination treatments. As an outlook, these results deserve to be transposed to larger size modules, which could present higher residual mechanical stress following harsh illumination treatments.
