High-efficiency Silicon Heterojunction Solar Cells: A Review
Abstract Silicon heterojunction solar cells consist of thin amorphous silicon layers deposited on crystalline silicon wafers. This design enables energy conversion efficiencies above 20% at the
Organometallic Halide Perovskites: Sharp Optical Absorption Edge and Its Relation to Photovoltaic Performance.
Using highly sensitive photothermal deflection and photocurrent spectroscopy, the absorption spectrum of CH3NH3PbI3 perovskite thin films at room temperature is measured, finding a high absorption coefficient with particularly sharp onset and a compositional change of the material.
Current Losses at the Front of Silicon Heterojunction Solar Cells
The current losses due to parasitic absorption in the indium tin oxide (ITO) and amorphous silicon (a-Si:H) layers at the front of silicon heterojunction solar cells are isolated and quantified.
Complex Refractive Index Spectra of CH3NH3PbI3 Perovskite Thin Films Determined by Spectroscopic Ellipsometry and Spectrophotometry.
The complex refractive index of planar CH3NH3PbI3 thin films at room temperature is investigated by variable angle spectroscopic ellipsometry and spectrophotometry and results agree well with previously reported data of the absorption coefficient and are consistent with Kramers-Kronig transformations.
Efficient Monolithic Perovskite/Silicon Tandem Solar Cell with Cell Area >1 cm(2).
A low-temperature process for semitransparent perovskite/crystalline silicon tandem solar cells is presented, yielding efficiencies up to 14.5%, and the effects of varying the intermediate recombination layer and hole transport layer thicknesses on tandem cell photocurrent generation are presented, experimentally and by transfer matrix simulations.
CH(3)NH(3)PbI(3) perovskite / silicon tandem solar cells: characterization based optical simulations.
The authors' characterization based simulations forecast that with optimized layer thicknesses the four-terminal configuration enables efficiencies over 30%, well above the current single-junction crystalline silicon cell record of 25.6%.
Organic-inorganic halide perovskite/crystalline silicon four-terminal tandem solar cells.
A four-terminal tandem solar cell consisting of a methyl ammonium lead triiodide top cell and a c-Si heterojunction bottom cell that exhibits broad-band transparency owing to its design free of metallic components and yields a transmittance of >55% in the near-infrared spectral region is presented.
>21% Efficient Silicon Heterojunction Solar Cells on n- and p-Type Wafers Compared
The properties and high-efficiency potential of front- and rear-emitter silicon heterojunction solar cells on n- and p-type wafers were experimentally investigated. In the low-carrier-injection
Silicon Heterojunction Solar Cells With Copper-Plated Grid Electrodes: Status and Comparison With Silver Thick-Film Techniques
Copper electroplating is investigated and compared with common silver printing techniques for the front metallization of silicon heterojunction solar cells. We achieve smaller feature sizes by
Low-Temperature High-Mobility Amorphous IZO for Silicon Heterojunction Solar Cells
Parasitic absorption in the transparent conductive oxide (TCO) front electrode is one of the limitations of silicon heterojunction (SHJ) solar cells efficiency. To avoid such absorption while
