Efficient Hybrid Solar Cells Based on Meso-Superstructured Organometal Halide Perovskites
TLDR
A low-cost, solution-processable solar cell, based on a highly crystalline perovskite absorber with intense visible to near-infrared absorptivity, that has a power conversion efficiency of 10.9% in a single-junction device under simulated full sunlight is reported.

Impedance spectroscopic analysis of lead iodide perovskite-sensitized solid-state solar cells.
TLDR
The features in the IS responses that are attributed to the ionic and electronic transport properties of the perovskite material and manifest as a slow response at low frequency and an additional RC element at intermediate frequency are explored.

11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials
TLDR
A record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global is reported using a hole-transport material composed of a blend of amorphous Cu(II/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 μm-thick mesoscopic TiO2 scaffold.

Influence of the donor size in D-π-A organic dyes for dye-sensitized solar cells.
We report two new molecularly engineered push-pull dyes, i.e., YA421 and YA422, based on substituted quinoxaline as a π-conjugating linker and bulky-indoline moiety as donor and compared with…

Lithium salts as "redox active" p-type dopants for organic semiconductors and their impact in solid-state dye-sensitized solar cells.
TLDR
The doping mechanism consumes Li(+) during the device operation, which poses a problem, since the lithium salt is required at the dye-sensitized heterojunction to enhance charge generation, and highlights that new additives are required to maximize the performance and the long-term stability of ss-DSSCs.
