Density-functional-theory-based molecular modeling (DFT/MM) of X-ray crystalline structure of PbI_6^\u003c4-\u003e/MeNH_3^+ salt (FOLLIB) verifies that the packing unit of FOLLIB has UV/Vis absorption spectrum at \u03bbmax = 424 nm, giving pale yellow color as complementary color. DFT/MM of the horizontal component in the FOLLIB gives narrow energy gap of 0.3 eV, verifying remarkable semiconducting property through tight alignments of PbI_6^\u003c4-\u003e components coupled with MeNH_3^+. DFT/MM of the central PbI_6^\u003c4-\u003e/MeNH_3^+ components verifies that the central component has UV/Vis absorption spectra with respective \u03bbmax = 570 nm, \u03bbmax  = 762 nm and \u03bbmax = 945 nm, and plays an essential role as panchromatic sensitizers. In addition, their equilibrium geometric structures show slightly hypsochromic UV/Vis absorption spectra at respective \u03bbmax = 486 nm, \u03bbmax = 560 nm, and \u03bbmax = 563 nm as results of migration of MeNH_3^+ close to PbI_6^\u003c4-\u003e. DFT/MM also verifies that PbI_6^\u003c4-\u003e components align tightly to nanocrystalline TiO_2 (nc-TiO_2) and to spiro-OMeTAD in PSC through electron density induced by van der Waals interaction. Electron density-based alignments of PbI_6^\u003c4-\u003e components well explain unidirectional and leakage-free electron diffusion leading to high open-circuit voltage in PbI_6^\u003c4-\u003e-aligned solar cells. At the same time, the semiconducting and panchromatic sensitizing layer of PbI_6^\u003c4-\u003e/MeNH_3^+ components contribute to excellent short-circuit photocurrent of PbI_6^\u003c4-\u003e-aligned solar cells.", "subitem_description_type": "Other"}, {"subitem_description": "\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "en", "subitem_1522300316516": "The Electrochemical Society"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/42932"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0013-4651"}, {"subitem_1522646500366": "ISSN", "subitem_1522646572813": "1945-7111"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "en", "subitem_1522650091861": "Journal of The Electrochemical Society"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2017", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "11", "bibliographicPageEnd": "E3605", "bibliographicPageStart": "E3598", "bibliographicVolumeNumber": "164"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "http://dx.doi.org/10.1149/2.0341711jes"}}, {"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "http://dx.doi.org/10.1149/2.0341711jes"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "J.
