Ag, Au, Pt prove best metal-contacts for perovskite solar cells. Ag and Cu are chemically unstable. Ni Cr show low performance.
Perovskite solar cells are well known for being low cost, solution‐based, and efficient cells; however, the high price of conventional hole‐collector electrode (Spiro‐OMeTAD/Gold) complexity depositing gold on large scales major barriers against commercializing them. Herein, an effective carbon composite is introduced a low‐cost perovskite cell with CuIn 0.75 Ga 0.25 S 2 hole transport material to solve this problem. The deposited by doctor blade method using paste composed flakes graphite,...
Solar cells with high efficiency, low cost, and stability are the target for new generation of solar cells. A fully printable perovskite (CH3NH3PbI3) cell (PSC) device architecture FTO/TiO2/Al2O3/NiOx/C is fabricated in current research as a low-cost relatively stable structure investigated to determine how different fabrication factors such thickness insulating spacer layer (Al2O3) or treatments heat UV-O3 can affect interfacial properties this multilayer mesoporous structure. X-ray...
Different polymers have been already introduced for passivating the interfacial defects at interface of perovskite and organic hole transport material, meanwhile as an environmental barrier in solar cells (PSCs). Herein, polyvinylcarbazole (PVK) compared to polymethylmethacrylate (PMMA) (Cs 0.05 (MA 0.83 FA 0.17 ) 0.95 Pb(Br I 3 layer CuInS 2 /carbon a low‐cost inorganic hole‐collecting electrode are investigated. By suppressing recombination using PMMA PVK, saturation current density (in...
Laser scribing is one of the most challenging steps in fabricating solar modules, which determines their internal resistance, geometrical factor, and efficiency. Pulsed Nd:YVO4 lasers with wavelengths 355, 532, 1064 nm are common used photovoltaic industry. As using single laser source for all more cost effective, this article after summarizing recent progress perovskite a nanosecond UV-laser (355 nm) needed series interconnections structures glass or plastic substrates studied how different...
To push perovskite solar cells (PSCs) as efficient solution-based with remarkable photovoltaic properties into large-scale production, in addition to improving efficiency and stability, reducing the fabrication cost, especially increasing manufacturing speed, is crucial. In this research, we have replaced conventional heating sintering procedure of a bilayer (compact mesoporous) TiO2 electron transport layer highly time- energy-consuming process fast light-curing for use PSCs promising...
Organic-inorganic hybrid semiconducting (OIHS) materials, which can detect broader spectral regions, are highly desired in several applications including biomedical imaging, night vision, and optical communications. Although lead (Pb)-halide perovskites have reached a mature research stage, high toxicity of Pb hinders their large-scale viability. Tin (Sn)-based the most common OIHS broadband light absorbers that replace toxic Pb; however, they extremely unstable due to notorious Sn2+...
Abstract Fluorine‐doped tin oxide (FTO) is replaced with chromium as the photoanode substrate in a dye‐sensitized solar cell (DSSC), and effect of chromium(III) on electron lifetime performance Cr‐based DSSC investigated compared conventional FTO‐based devices. It shown that Cr stable chemically aggressive iodide‐based electrolyte, which can be attributed to compact overlayer. The chromium‐oxide layer also effectively blocks recombination from substrate, while hindering transfer TiO 2 film...
In contrast to conventional sandwich-type dye-sensitized solar cells, we investigated an all-metal-electrode bracken-like single-sided structure.
