Versatile perovskite photo voltaic modules are rising as a candidate for light-weight, bendable photovoltaics, however sustaining excessive effectivity whereas preserving long run stability and low price stays troublesome. A analysis group from the Institute of Steel Analysis of the Chinese language Academy of Sciences and Zhengzhou College stories versatile perovskite photo voltaic modules with energy conversion effectivity exceeding 20 p.c that tolerate mechanical and environmental stresses. The work focuses on single walled carbon nanotube movies used as window electrodes in scalable versatile perovskite photo voltaic modules.
The group reveals that single walled carbon nanotube movies are hydrophobic, which helps block moisture and slows degradation of the perovskite layer, enhancing system stability. Their mechanical flexibility and comparatively low materials price make these carbon nanotube electrodes appropriate for utility in distributed energy era built-in into buildings and infrastructure that assist lowered carbon emissions.
A central step within the examine is remedy of the carbon nanotube community with sulfuric acid. The acid remedy will increase {the electrical} conductivity of the nanotube movies and promotes interplay with nickel oxide to kind a compact NiSO4 – NiOx layer on the interface.
This interfacial layer improves cost switch between the perovskite absorber and the outlet transport materials, enabling indium tin oxide free perovskite photo voltaic cells to succeed in greater than 24 p.c energy conversion effectivity, with versatile units sustaining roughly 23 p.c. Beneath excessive temperature, excessive humidity, and steady photo voltaic illumination for one month, these units retained greater than 95 p.c of their preliminary effectivity.
The researchers additionally fabricated versatile, module scale, indium tin oxide free units utilizing an easy and scalable course of, attaining greater than 20 p.c effectivity with improved stability and bending efficiency. The work additional demonstrates that single walled carbon nanotube movies might be produced on meter scale substrates via a chemical vapor deposition primarily based roll to roll course of, which helps bigger space manufacturing of carbon nanotube primarily based perovskite modules.
Collectively, the findings point out that sulfuric acid handled carbon nanotube electrodes ready by established acidic processing routes can elevate each efficiency and sturdiness in versatile perovskite photo voltaic applied sciences.
