Eliminating the Perovskite Solar Cell Manufacturing Bottleneck via High‐Speed Flexography

چکیده
Perovskite solar cells have potential to deliver terawatt-scale power via low-cost manufacturing. However, scaling is limited by slow, high-temperature annealing of the inorganic transport layers and lack reliable, large-area methods for depositing thin (< 30 nm) charge (CTLs). We present a method ultrathin NiOx hole (HTLs) pairing high-speed (60 m/min) flexographic printing with rapidly annealed sol-gel inks achieve fastest reported process fabrication CTLs perovskites. By engineering precursor rheology rapid film-leveling, HTLs were printed high uniformity ultralow pinhole densities resulting in photovoltaic performance exceeding that spin-coated devices. Integrating these planar inverted PSCs allows efficiency (PCE > 15%) Cs(x)FA(1-x)PbI improved short circuit currents (Jsc) 22.4 mA/cm2. Rapid HTL accelerates total processing time 60X, while maintaining required balance optoelectronic properties chemical composition effective collection. These results build an understanding reveal opportunities enhance device scalable manufacturing CTLs.

Planar heterojunction perovskite solar cells via vapor-assisted solution process.
Hybrid organic/inorganic perovskites (e.g., CH3NH3PbI3) as light absorbers are promising players in the field of third-generation photovoltaics. Here we demonstrate a low-temperature vapor-assisted solution process to construct polycrystalline perovskite thin films with full surface coverage, small surface roughness, and grain size up to microscale. Solar cells based on the as-prepared films ac...

Two-dimensional hybrid perovskites are used as absorbers in solar cells. Our first-generation devices containing (PEA)2(MA)2[Pb3I10] (1; PEA=C6H5(CH2)2NH3 , MA= CH3NH3 ) show an open-circuit voltage of 1.18 V and a power conversion efficiency of 4.73%. The layered structure allows for high-quality films to be deposited through spin coating and high-temperature annealing is not required for devi...
متن کاملThe Dawn of Lead‐Free Perovskite Solar Cell: Highly Stable Double Perovskite Cs2AgBiBr6 Film
Recently, lead-free double perovskites have emerged as a promising environmentally friendly photovoltaic material for their intrinsic thermodynamic stability, appropriate bandgaps, small carrier effective masses, and low exciton binding energies. However, currently no solar cell based on these double perovskites has been reported, due to the challenge in film processing. Herein, a first lead-fr...
