We demonstrate four- and two-terminal perovskite-perovskite tandem solar cells with ideally matched band gaps. We develop an infrared-absorbing 1.2-electron volt band-gap perovskite, FA0.75Cs0.25Sn0.5Pb0.5I3, that can deliver 14.8% efficiency. By combining this material with a wider-band gap FA0.83Cs0.17Pb(I0.5Br0.5)3 material, we achieve monolithic two-terminal tandem efficiencies of 17.0% wit...
In this review, we summarize recent works on perovskite solar cells with neutral- and multi-colored semitransparency for building-integrated photovoltaics and tandem solar cells. The perovskite solar cells exploiting microstructured arrays of perovskite "islands" and transparent electrodes-the latter of which include thin metallic films, metal nanowires, carbon nanotubes, graphenes, and transpa...
Organic–inorganic metal halide perovskite solar cells represent the fastest advancing cell technology in terms of energy conversion efficiency improvement, as seen last decade. This has become a promising for next-generation, low-cost, high-efficiency photovoltaics including multi-junction tandem concepts. Double-junction have much higher limits 45%, beyond Shockley–Queisser single-junction cel...

The light instability of CH3NH3PbI x Br3-x is one of the biggest challenges for its application in tandem solar cells. Here we show that an improved crystallinity and grain size of CH3NH3PbI x Br3-x films could stabilize these materials under one sun illumination, improving both the efficiency and stability of the wide-bandgap perovskite solar cells.
In this paper, we simulated a double junction cell based on top CdS/Cu2ZnSnS4 cell, stacked bottom CdS/Cu2ZnSnSe4 cell. We started by studying the perfomance of solar copper zinc tin selenide Cu2ZnSnSe4 (CZTSe) absorber. Then, evaluated photovoltaic parameters tandem at optimized thickness sulfide Cu2ZnSnS4 (CZTS) absorber where and cells deliver same photocurrent density. achieved A maximum ef...
III-Sb semiconductors cover the whole 0.29–1.64 eV bandgap range, allowing us to grow several subcells of a multi-junction solar cell lattice-matched GaSb. Among alloys, AlInAsSb exhibits broadest range direct bandgaps, making it promising material for photovoltaic applications. In this work, behavior two AlInAsSb/GaSb tandem cells is studied. Material characterization and physics-based 1D mode...
a commercial ti-nanoxide was deposited on in-doped sno2 (ito) polymer substrates by tape casting technique with different thicknesses (7, 14 and 36μm) to be used as photoelectrode in flexible dye-sensitized solar cells (dsscs). ruthenium dye was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...
