Many different photovoltaic technologies are being developed for large-scale solar energy conversion. The wafer-based first-generation photovoltaic devices have been followed by thin-film solid semiconductor absorber layers sandwiched between two charge-selective contacts and nanostructured (or mesostructured) solar cells that rely on a distributed(More)
Information of the cultural heritage, especially cultural relics, historical architectures and memorial sites, firstly represents their location and time, and then are their cultural or historical attributes and meanings. Moreover, environment and planning also are important information for the protection of urban cultural heritage. Therefore, a lot of the(More)
The organic-inorganic hybrid perovskites methylammonium lead iodide (CH3NH3PbI3) and the partially chlorine-substituted mixed halide CH3NH3PbI3-xClx emit strong and broad photoluminescence (PL) around their band gap energy of ∼1.6 eV. However, the nature of the radiative decay channels behind the observed emission and, in particular, the spectral broadening(More)
