b S Supporting Information ' INTRODUCTION Dye-sensitized solar cells (DSCs) have displayed significant potential to compete with silicon-based cells in the future. 1 Conventional DSCs rely on a high-surface-area, nanoparticulate TiO 2 framework, chemisorbed with a monolayer of high molar extinction dye to harvest the majority of incoming photons.

We fabricated perovskite solar cells using a triple-layer of n-type doped, intrinsic, and p-type doped 2,2',7,7'-tetrakis(N,N'-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD) (n-i-p) as hole transport layer (HTL) by vacuum evaporation. The doping concentration for n-type doped spiro-OMeTAD was optimized to adjust the highest occupied molecular(More)
Low-bandgap diketopyrrolopyrrole-and carbazole-based polymer bulk-heterojunction solar cells exhibit much faster charge carrier recombination kinetics than that encountered for less-recombining poly(3-hexylthiophene). Solar cells comprising these polymers exhibit energy losses caused by carrier recombination of approximately 100 mV, expressed as reduction(More)
