In this study a novel high efficiency crystalline silicon (c-Si) solar cell concept is presented. It combines Interdigitated Back Contact (IBC) structures with Silicon Heterojunction (Si-HJ) technology through the use of Laser assisted patterning steps. The SLASH (Structuring by Laser Ablation of Silicon Heterojunction) IBC cell shows a simplified geometry(More)
An alternative way to conventional solar cell process is to develop a low temperature process using hydrogenated amorphous silicon (a-Si:H) thin film deposited by PECVD on bulk crystalline silicon. The French national project "SiNERGIES" aims to improve polymorphous/crystalline heterojunction (a-Si:H/pm-Si:H/c-Si) on p-type crystalline silicon (c-Si) to(More)
In this paper, we present our recent work concerning the industrialization of hydrogenated amorphous/crystalline silicon heterojunction cells (a-Si:H/c-Si HET). Indeed, if efficiencies up to 20.5% have already been announced by INES solar cell group, not all developed processes are fully compatible with industrial constraints because of cost and throughput(More)
In this work, we have studied the scalability of our fabrication process for heterojunction solar cells up to 148.5cm<sup>2</sup> total area. Double heterojunction devices were fabricated on both n- and p-type textured substrates using only doped (n) and (p) a-Si:H layers. ITO was used as anti-reflective coating and evaporated Aluminum as the metallic back(More)
A novel approach for the silicon thin-film solar cells transfer technology was developed at INSA-LYON, named ELIT process (Epitaxial Layers for Interdigitated back contacts solar cells Transferred using porous silicon). In this paper, all the process steps are described. Starting from the formation of a double porous silicon layer on the whole substrate(More)
In the actual PV context, it is mandatory to address cost reduction maintaining very high efficiency to be competitive. In the case of amorphous/crystalline heterojunction technology (HET), cost pareto is driven by Silver consumption by screen printing pastes followed by Silicon substrate. One option is to substitute Silver by Cu plating. Regarding material(More)
