On the upconversion efficiency of luminescent materials for effective use in solar cells

Based on the present upconversion efficiency of rare earth doped nanocrystals, we estimated the necessary upconversion efficiency of luminescent materials to effectively enhance the efficiency of solar cells. Emission enhancement of luminescent material by surface plasmons resonance was investigated. The detail study on quenching of enhanced near-field of metallic photonic crystal by luminescent materials was performed by finite difference time domain simulation.
