The back-contact crystalline silicon solar cell represents an advanced configuration in which inter-digitated positive and negative contacts are placed on the rear surface.
4. Conclusions The poly-Si on the back has a great impact on the performance of TOPCon solar cells. In the case of narrow band system, the quantum well formed at the valence band at the interface of poly-Si leads to the accumulation of holes, which makes the recombination rate surge and leads to poor device performance.
Compared with the mainstream solar cell technologies such as PERC and HJT, TOPCon solar cells use a tunneling layer on the back side to reduce the carrier recombination between the metal electrode and silicon.
This review provides a comprehensive overview of back-contact (BC) solar cells, commencing with the historical context of the inception of the back-contact silicon (BC-Si) solar cells and its progression into various designs such as metallization wrap through, emitter wrap through, and interdigitated configurations.

This chapter reviews growth and characterization of Czochralski silicon single crystals for semiconductor and solar cell applications. Magnetic-field-applied Czochralski growth systems and unidirectional solidification systems are the focus for large-scale integrated (LSI) circuits and solar applications, for which control of melt flow is a key issue to realize high-quality crystals.
Silicon is also used for about 90% of all photovoltaic cell material (solar cells), and single crystal silicon is roughly half of all silicon used for solar cells. In solar cells, single crystal silicon is called "mono" silicon (for "monocrystalline") [15,16]. Single crystal silicon for semiconductor devices is grown dislocation free by the Czochralski (Cz) and floating zone (FZ ...
Compared with the mainstream solar cell technologies such as PERC and HJT, TOPCon solar cells use a tunneling layer on the back side to reduce the carrier recombination between the metal electrode and silicon.
