Interdigitated back contact silicon heterojunction solar cells featuring an interband tunnel junction enabling simplified processing

Paviet-Salomon, B.; Tomasi, A.; Lachenal, D.; Badel, N.; Christmann, G.; Barraud, L.; et al. (2018)

This paper reports on the development of an innovative back-contacted crystalline silicon solar cell with passivating contacts featuring an interband tunnel junction at its electron-collecting contacts. In this novel ...
Optimization of tunnel junction IBC solar cells based on a series resistance model

Lachenal, D.; Papet, P.; Legradic, B.; Kramer, R.; Kossler, T.; Andreetta, L.; et al. (2019)

This work presents the upscaling of the tunnel IBC technology on large area, Czochralski (Cz) n-type wafers. At the junction level, a self-aligned PECVD masking technology has been developed for the deposition of hydrogenated ...
