TL;DR: The findings in this study indicate that careful surface engineering to reduce this potential barrier is key to pushing perovskite solar cell efficiencies toward the theoretical limit.

TL;DR: This work highlights the potential of CH3NH3PbI3 as a new candidate for ultrafast spin switches in spintronics applications and elucidates the electron spin relaxation lifetime to be ∼7 ps and that of the hole is ∼1 ps through a simple two-level model.

TL;DR: A low temperature route to synthesize graphene oxide-Pt nanoparticle hybrid composite by light assisted spontaneous coreduction of graphene oxide and chloroplatinic acid without reducing agent is demonstrated and indicates the importance of light as energy provider and ethanol as hole scavenger in the formation of small Pt nanoparticles.

TL;DR: In this paper, the energy level alignment at the CH3NH3PbI3/copper phthalocyanine (CuPc) interface was investigated by X-ray photoelectron spectroscopy (XPS) and ultraviolet photo-electron spectrum analysis (UPS), which revealed a 0.3 eV downward band bending in the CuPc film.

TL;DR: In this paper, a high surface area, nanofibrillar, electrospun TiO 2 thin films with intact fiber morphology as photoanodes in dye-sensitized solar cells has been demonstrated.
