The investigated HTM was synthesized via one-step catalyst-free condensation reaction from commercially available and extremely cheap starting reagents, resulting in a fractional cost of the final product compared to the commercial spiro-OMeTAD. This material promises to be a viable p-type organic semiconductor to be employed in the manufacturing of perovskite solar modules.EnglishHOLE-TRANSPORTING MATERIALSACTIVE MATERIALSPERFORMANCEScience & TechnologyTechnologyFacile and Low-Cost Design Alternative of Spiro-OMeTAD as p-Type Semiconductor for Efficient Perovskite Solar Cellstext::journal::journal article::research article
