We adopt the impedance spectroscopy to enlighten on the modification of the carrier transport mechanisms across the Spiro-OMeTAD\/perovskite interface constituting the active part where the main device processes occur. We investigate two interface structures referred to as the direct (or regular, n-i-p) and the inverted (p-i-n) configuration.  This work is also intended to further stress on the possible adoption of alternative device structures working with undoped hole transport materials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ambrico Marianna; Ambrico Paolo F.; De Marco Luisa; Iacobellis Rosabianca; D&#8217;Abramo Arianna; Ligonzo Teresa<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[574],"product_tag":[1133,1134],"class_list":["post-6695","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-journal-articles","product_tag-impedance-spectroscopy","product_tag-perovskite-solar-cells","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/6695","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=6695"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=6695"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=6695"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=6695"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
