Semi-transparent perovskite solar cell
A semi-transparent perovskite solar cell (ST-PSC) generates electricity from a metal halide perovskite absorber while transmitting visible light, serving solar windows, building-integrated photovoltaics, and tandem solar cells.
Solution processing of perovskite solar cells
Solution processing of perovskite solar cells is the fabrication of perovskite films by depositing dissolved precursors and crystallizing them at low temperature, enabling printing and roll-to-roll production.
Solvent engineering for perovskite films
Solvent engineering for perovskite films controls how thin films crystallize by choosing solvents and an antisolvent, such as toluene, during spin coating; it underpins most high-efficiency perovskite solar cells.
Spiro-OMeTAD
Spiro-OMeTAD, first described in 1998, is an amorphous organic p-type semiconductor used as the benchmark hole-transporting material in perovskite and solid-state dye-sensitized solar cells, enabling certified devices above 26% efficiency.
Surface passivation of perovskite solar cells
Surface passivation of perovskite solar cells is the treatment of the perovskite layer's surface to neutralize charge-trapping defects, driving efficiencies from 3.8% in 2009 past 26%.
T80 lifetime
T80 lifetime is the time a solar cell takes to fall to 80% of its initial power conversion efficiency, the standard stability measure for perovskite cells.
Tin halide perovskite
Tin halide perovskite is a lead-free perovskite semiconductor in which tin replaces toxic lead, the leading lead-free absorber for perovskite solar cells at up to 17.71% efficiency.
Tin oxide electron transport layer
A tin oxide electron transport layer (SnO2 ETL) is a thin tin dioxide film in perovskite solar cells that extracts electrons to the electrode while blocking holes.
Tin-lead perovskite solar cells
Tin-lead perovskite solar cells are photovoltaic devices with a mixed tin-lead perovskite absorber of roughly 1.2 eV bandgap, used as the bottom subcell in all-perovskite tandems.
Triple-cation perovskite
A triple-cation perovskite is a metal-halide perovskite for solar cells whose A-site mixes cesium, methylammonium, and formamidinium; introduced in 2016, it became a baseline for high-efficiency devices.
Triple-junction perovskite solar cell
A triple-junction perovskite solar cell stacks three light-absorbing subcells, at least one a metal halide perovskite, to convert more of the Sun's energy than a single junction.
Two-terminal tandem
A two-terminal tandem, or 2T tandem, is a tandem solar cell with two series-connected subcells accessed through two terminals; perovskite/silicon devices have reached a certified 33.7% efficiency.
Wide-bandgap perovskite
A wide-bandgap perovskite is a metal-halide perovskite absorber with a bandgap of roughly 1.65 to 2.0 eV, serving as the high-voltage front cell in tandem solar cells.
Wide-bandgap perovskite solar cells
Wide-bandgap perovskite solar cells are photovoltaic devices based on mixed iodide-bromide perovskites with bandgaps above 1.7 eV, serving as the top subcells of perovskite/silicon tandems that have reached about 35% efficiency.
