Ultrasensitive solution-processed broad-band photodetectors using CH3NH3PbI3 perovskite hybrids and PbS quantum dots as light harvesters
TL;DR: This work demonstrates solution-processed ultrasensitive broad-band photodetectors utilizing organolead halide perovskite materials and PbS quantum dots as light harvesters using diminutive molecular-scaled CH3NH3PbI3 and shows device performance parameters comparable to those from pristine inorganic counterparts.
Journal ArticleDOI
Enhanced Performance of Fullerene n-Channel Field-Effect Transistors with Titanium Sub-Oxide Injection Layer
TL;DR: In this paper, a titanium suboxide (TiOx) injection layer was introduced to improve the performance of n-channel organic field-effect transistors (OFETs) by reducing the electron injection barrier.

TL;DR: In this article, three new n-type copolymers were synthesized using the isoindigo monomer, i.e., 5-Octylthieno[3,4-c]pyrrole-4,6-dione (TPD), 5-5′-dioctyl-1,1′-4H-bithieno [3, 4-c]-pyrdrug-4-6-tetrone (BTPD), and 3, 6-bis(thiophen-2-yl)-2
Journal ArticleDOI
Direct evidence of photoinduced electron transfer in conducting-polymer-C60 composites by infrared photoexcitation spectroscopy.
TL;DR: The lifetime of the excited-state configuration, (P3OT)[sup +] and C[sub 60][sup [minus]], is extended; thereby leading to both the enhanced photoinduced response of P3OT and the appearance of the 1.15- and 1.25-eV signatures associated with C[ sub 60][Sup [ minus]].
Journal ArticleDOI
Additive-Free Bulk-Heterojuction Solar Cells with Enhanced Power Conversion Efficiency, Comprising a Newly Designed Selenophene-Thienopyrrolodione Copolymer
TL;DR: In this article, a selenophene-thienopyrrolodione (TPD) copolymer blended with [6,6]-phenyl C71 butyric acid methyl-ester was used to achieve an enhanced power conversion efficiency (PCE).
