Lanthanides in Solar Energy Conversion

Structural, optical and electrical properties of Nd-doped SnO2 thin films fabricated by reactive magnetron sputtering for solar cell devices

“…The concept is that the incident photons from the solar spectrum can be converted to photons that match better the absorption wavelength range of the solar cell. For instance, by placing DC or DS layers in front of the solar cell, higher energy UV photons that cause thermalization losses can be converted into visible or near infrared lower energy photons, which can be absorbed by the cell [6][7][8]. Down conversion process is when more than one photon is produced from one high energy photon.…”

Effect of the Li+ ion on the multimodal emission of a lanthanide doped phosphor

“…In the bio-imaging research, the upconversion (UC) property of lanthanide nano-particles is used as it is expected to enhance the bio-imaging from various perspectives including penetration depth, lower scattering, negligible auto-uorescence, high signal-to-noise ratio, etc. [18][19][20] Thus, lanthanide doped phosphor capable of multi-modal emission is new trust for solar cell research and are being actively explored. energy harvesting, fully utilizes the unique multi-modal (uorescence (PL), UC and downconversion/quantum-cutting (QC)) emission characteristics of lanthanide ions.…”

“…Their outstanding photophysical properties and specific behaviour towards f-f emission, together with their variable luminescence lifetimes and high quantum yield make lanthanide ions an important class of luminescent materials in a large number of advanced novel applications in various modern technologies (1)(2)(3)(4)(5). Also, characteristic sharp bands in the near-infrared (IR) region of several lanthanide ions make them efficient materials for use in other technologies such as biomedical imaging (6)(7)(8)(9), lasers and Organic Light Emitting Diode (OLED) devices (10,11).…”
