What is the conversion efficiency of crystalline silicon heterojunction solar cells?

Masuko, K. et al. Achievement of more than 25% conversion efficiency with crystalline silicon heterojunction solar cell. IEEE J. Photovolt. 4, 1433–1435 (2014). Boccard, M. & Holman, Z. C. Amorphous silicon carbide passivating layers for crystalline-silicon-based heterojunction solar cells. J. Appl. Phys. 118, 065704 (2015).

How efficient is a c-Si solar cell?

Yet, for c-Si mass production, a solar cell efficiency of 26% is considered by many as a practical limit. An open question is, thus, what could come next in terms of efficiency. Today, the only proven concept to further increase efficiency is the combination of solar cells in a multi-junction configuration.

Can silicon solar cells improve power conversion efficiency?

Provided by the Springer Nature SharedIt content-sharing initiative Silicon solar cells are a mainstay of commercialized photovoltaics, and further improving the power conversion efficiency of large-area and flexible cells remains an important research objective1,2.

How efficient are solar cells?

Today, the only proven concept to further increase efficiency is the combination of solar cells in a multi-junction configuration. Using silicon as a bottom cell, 4-terminal tandem devices have shown up to 32.8% efficiency (GaAs on Si) and 4-terminal triple-junction devices reached 35.9% efficiency (GaIn/GaAs on Si) 208.
