Cost management and toxic waste generation are two key issues that must be addressed before the commercialization of perovskite optoelectronic devices. We report a groundbreaking strategy for eco-friendly cost-effective fabrication highly efficient solar cells. This involves usage high volatility co-solvent, which dilutes precursors to lower concentration (<0.5 M) while retaining similar film quality device performance as (>1.4 solution. More than 70% material cost can reduced. Mechanistic...
Abstract The perovskite solar era has demonstrated 25.5% efficiency in only 10 years of research, reaching the performance levels other photovoltaics technologies such as Si and GaAs, showing potentially low‐cost manufacturing process versatility. However, these results are achieved on small area cells, with an active equal or lower to 0.1 cm 2 . upscaling development technology requires use additional processes reduce losses encountered for large areas; this reason, laser processing becomes...
As the hole transport layer (HTL) for perovskite solar cells (PSCs), poly(3-hexylthiophene) (P3HT) has been attracting great interest due to its low-cost, thermal stability, oxygen impermeability, and strong hydrophobicity. In this work, a new doping strategy is developed P3HT as HTL in triple-cation/double-halide ((FA1-x-y MAx Csy )Pb(I1-x Brx )3 ) mesoscopic PSCs. Photovoltaic performance stability of show remarkable enhancement using composition three dopants Li-TFSI, TBP, Co(III)-TFSI...
The commercialization of perovskite solar cells (PSCs) has seen an important limitation in the instability that afflicts hole-transporting layer (HTL), namely, spiro-OMeTAD, used high-efficiency devices. latter is, turn, relatively expensive, undermining sustainability device. Its replacement with polymeric scaffolds, such as poly(3-hexylthiophene) (P3HT), will solve these issues. In this work, we adopted various sustainable synthetic methods to obtain four different homemade P3HTs molecular...
In the present work we used some crystallization trends which could be classified as a Crystal Engineering (CE) approach, for deposition of pure cubic-phase thin film CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> (MAPbI<sub>3</sub>) on surface mesoporous TiO<sub>2</sub> layer.

The fully optimized equilibrium structures cobalt(II/III)-tris-bipyridine complexes in gas phase acetonitrile solvent are obtained by density functional B3LYP method using LanL2DZ 6-31G(d,p) basis sets. harmonic vibrational frequencies,...
Here, we successfully used a pure layer of [SiW11 O39 ]8- polyoxomethalate (POM) structure as thin-film scaffold for CH3 NH3 PbI3 -based perovskite solar cells (PSCs). A smooth nanoporous surface POM causes outstanding improvement the photocurrent density, external quantum efficiency (EQE), and overall PSCs compared to mesoporous TiO2 (mp-TiO2 ) layer. Average power conversion (PCE) values 15.5 % with champion device showing 16.3 could be achieved by using sequential deposition method...
