Upconversion (UC) of subbandgap photons has the potential to increase solar cell efficiencies. In this paper, we first review our recent investigations of silicon solar cell devices with an attached upconverter based on β-NaYF4 :20%Er3+. Such device

We describe some fundamental properties of localized plasmon polaritons in metallic nanoparticles, and discuss their use for enhancing solar cells efficiency by photon management. Two scenarios are detailed. The first is an example of spectral photon

Upconversion (UC) of sub-band-gap photons can increase solar cell efficiencies. Up to now, the achieved efficiencies are too low, to make UC relevant for photovoltaics. Therefore, additional means of increasing UC efficiency are necessary. In this pa

Upconversion of sub-bandgap photons has been suggested to increase the efficiencies of silicon solar cells. Using model calculations we show that gold nanoparticles can enhance the upconversion intensities from erbium ions in a relevant geometry.

In conventional silicon solar cells, photons with energies lower than the silicon band gap (1.12 eV) are not absorbed in the silicon layer. However, the near-infrared portion of the solar spectrum may still be able to contribute to photocurrent gener
