In pursuit of preparing efficient quantum dot light-harvesting sensitizers over mesoporous TiO2 films, an improved successive ionic layer adsorption and reaction (SILAR) process in chemical baths was found to be very effective for depositing and growing various QDs such as CdS, PbS, PbS/CdS, CdSe, CdS/CdSe, and CdSe/CdTe in a both systematic and reproducible way; precursors of QDs delivered sequentially to the surface of TiO2 in chemical baths were adsorbed and reacted directly onto the substrates. The as-prepared QD-sensitized electrodes were combined with a regenerative redox couple, Co(II/III) or a polysulfide electrolyte in a liquid-type cell, and their photovoltaic properties and kinetic parameters were obtained for the evaluation of those QD sensitized-cells. After a series of thorough optimization steps, almost all the tested cells gave over 1~4 % overall power conversion efficiencies and unprecedented high incident photon-to-current efficiencies (IPCEs) when compared with previous results. In this talk, general strategies for making efficient QD- and its dye hybrid-sensitized mesoporous TiO2 solar cells will be presented with future prospects of QD-based solar cells as well as their current limitations.     #,/01ABCIVWʼ管vh[I,8h>rh>r5CJOJPJQJ^JaJfHq #h>rhu+5CJOJQJ^JaJh,5CJOJaJo(h,h,6CJOJaJh,h,6OJhXkh1BOJaJh,>*OJaJo(hD7>*OJaJo(hjh1BCJOJaJhXkh1B5CJOJ\h~V5CJH*OJ\o( hibnh~V5CJH*OJ\o(h~V5CJOJ\o(hibn5CJOJ\o(h,5CJOJ\o(BCW     gdfAgd1BgdoE $dha$gdxgd1B$a$gd,$a$gd1B $dha$gd1B G P ` d m ɬtY<"2h5CJOJPJQJ^JaJfHq 8h>rh5CJOJPJQJ^JaJfHq 5hl5CJOJPJQJ^JaJfHo(q ;h>rh>r5CJH*OJPJQJ^JaJfHq 2he5CJOJPJQJ^JaJfHq 8h>rh>r5CJOJPJQJ^JaJfHq 5he5CJOJPJQJ^JaJfHo(q 5h?5CJOJPJQJ^JaJfHo(q ĩqSqA:-hxh1BCJOJaJ hxh>r#hxhx5CJOJQJ^JaJ;hxhx5CJH*OJPJQJ^JaJfHq 8hxhx5CJOJPJQJ^JaJfHq 5h5CJOJPJQJ^JaJfHo(q 5he5CJOJPJQJ^JaJfHo(q 8h>rh>r5CJOJPJQJ^JaJfHq ;h>rh>r5CJH*OJPJQJ^JaJfHq     hJjhJUhoEhYOJh&OJmHo(sH :&P 1h2P:pjO( 8!"#$%S b 2 0@P`p2( 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p8XV~PJ_HmH nHsH tHR`R \$1$4$7$8$a$ KHOJ_HaJmH nHsH tH(A ( 0 } 4FiF \ \ :V 44 la $k $] L \^@\ | ()"$dd1$4$7$8$[$\$a$CJKHOJPJQJ$B@$ 8CJ.U`. 1BXt|l >*B*ph0"0 fA8 B#G$4o14 fA8 Char KHOJaJ0 B0 fA B#G$4oQ4 fA Char KHOJaJ~Ob~ >r MsoBodyText&$d-D9DG$M a$'5B*CJKHOJPJQJ\^JphbOrb >r d-D9DG$M !B*KHOJPJQJ^JaJphPK![Content_Types].xmlN0EH-J@%ǎǢ|ș$زULTB l,3;rØJB+$G]7O٭V537%һ;HO:ԵRa<% ̍W.ݘ--jK11 O?ȩH>M8K 6دk.~8$w &^Kx=[Ԃu}e eSih]*S^ z}4i6kNN󴻵fKWdnu:f+5 ؘïVހ,9ot6Uo@:_h6\E&sh~?^@ƜmWV3DC]Ř'jQ6}h Ê&HMS2>CoR/4G$}ASO1$ƌꋧ߿x}rt{h 9qWUr/_䗟& I4W~{ן 2|Hc"5rx x$8K)f!o ("U˓ێHLx%Eh^%3'IX\Lʸ=xwq7Iz*݈8b2((>!ݢԱ|-:Vdұ42f&pե9葐U?$1eܠ#,@DT2Nl)5Pڝ5o(ϾyP!Z7̜czxr7FoIK -7%m%zQ>}ab(Ӻ%Mi26PSFJӄK؁> uIYd`B$h2#Jr G3\I[챳$rHvx`Wp~(Bsher!# fu-ԩՍh(: L^5AW@#f$v>bp.H#Iy)'Xĭɾ8̮]WR3/ȒrrVs!mo gfxS$f!dhb6lt#h &Mʚ6k;݂1ckN4vќ\ ނ &f%0Y7PK! ѐ'theme/theme/_rels/themeManager.xml.relsM 0wooӺ&݈Э5 6?$Q ,.aic21h:qm@RN;d`o7gK(M&$R(.1r'JЊT8V"AȻHu}|$b{P8g/]QAsم(#L[PK-![Content_Types].xmlPK-!֧6 0_rels/.relsPK-!kytheme/theme/themeManager.xmlPK-!stheme/theme/theme1.xmlPK-! ѐ' theme/theme/_rels/themeManager.xml.relsPK]       @ @H 0(  0(  B S  ?1;ILMRpw{=@BEGJKNPTVYZ^dhimx | 3 #A @@3,WFQSRoE_qc& N #P wZ @7y:1B>9[ $&+(u+K3<4D7?+BFTGKU{PRYpHZX^os_>difXkClibn>rt twvF5w{?| }j13&Oj)jqM]VT.@~V^l+XRxeoO,JMRYNyfAIXbvhkz1@ h@UnknownG*Ax Times New Roman5Symbol3. *Cx Arial/ |i0д;|i0BatangI> ??Arial Unicode MS9> |i0tGulimA$BCambria Math q hF:%gG:%gAŴF  )("!%),.:;?]}  2 3 ! 0 0 0000 =]([\{  0 0 0000;[23qKX? t2!xx &Flexible 1-D Photonic Plastic Replicastwimh108AjouOh+'0h   $ 0 <HPX`(Flexible 1-D Photonic Plastic Replicas twimh108NormalAjou3Microsoft Office Word@@U9h@ i@*VDi՜.+,0 hp  nano  'Flexible 1-D Photonic Plastic Replicas   !"#$%'()*+,-0Root Entry F1Fi21TableWordDocument<SummaryInformation(DocumentSummaryInformation8&CompObjn  FMicrosoft Word 97-2003 MSWordDocWord.Document.89q
