Photovoltaic cells are able to convert sunlight into electricity, providing
enough of the most abundant and cleanest energy to cover our energy needs.
However, the efficiency of current photovoltaics is significantly impeded by the
transmission loss of sub-band-gap photons. Photon upconversion is a promising
route to circumvent this problem by converting these transmitted sub-band-gap
photons into above-band-gap light, where solar cells typically have high quantum
efficiency. Here, we summarize recent progress on varying types of efficient
upconversion materials as well as their outstanding uses in a series of solar
cells, including silicon solar cells (crystalline and amorphous), gallium
arsenide (GaAs) solar cells, dye-sensitized solar cells, and other types of solar
cells. The challenge and prospect of upconversion materials for photovoltaic
applications are also discussed.
