Charge carrier dynamics in perovskite CH3NH3PbI3 solar cells were studied by means of microscopic photoluminescence (PL) and photocurrent (PC) imaging spectroscopy. The PL intensity, PL lifetime, and(More)
Organic-inorganic halide perovskite solar cells are attracting much attention from the photovoltaic community because of their high conversion efficiencies exceeding 20%. So far, intrinsic superior(More)
Organic-inorganic hybrid perovskite solar cells are attracting much attention due to their excellent photovoltaic properties. In these multilayered structures, the device performance is determined by(More)
As a key precursor for perovskite layer, we developed a complex of CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf>(dmf). The higher solubility of this complex in DMSO compared to the conventional(More)
The fast-decaying component of photoluminescence (PL) under very weak pulse photoexcitation is dominated by the rapid relaxation of the photoexcited carriers into a small number of carrier-trapping(More)
