摘    要:用MEH-PPV为给体(空穴传输)、C60为受体(电子传输)首先制备了分层和体异质结结构的两种器件,器件结构为ITO/PEDOT:PSS/MEH-PPV/C60/Al和ITO/PEDOT:PSS/MEH-PPV:C60/Al。之后又制备了结构为ITO/PE-DOT:PSS/MEH-PPV:C60/C60/Al的第3个器件。作者比较了这3种器件的光伏性质,发现器件3的短路电流密度(JSC)比器件1和器件2的分别增加了300%和150%,开路电压(VOC)分别增加了100%和20%。这主要是由于C60层增加了电子由受体传输到负电极的通道并增大了给体受体界面面积。另一原因是此C60层一定程度地阻挡了空穴从有机物向负极的传输,从而有效地改善了太阳电池的性能。

关 键 词:太阳电池  体异质结  短路电流密度JSC  开路电压VOC

Abstract:Two solar cells with the device structures of ITO/PEDOT:PSS/MEH-PPV/C60/Al and ITO/PEDOT:PSS / MEH-PPV:C60/Al,in which poly 1,4-(2-methoxy-5-ethylhexyloxy)phenylenevinylene(MEH-PPV) is used as electron donors and fullerene(C60) is used as electron acceptors,were fabricated.Then the third device with the structure of ITO/PEDOT:PSS/PPV:C60/C60/Al was fabricated.We compared the photovoltaic properties of these devices and found that short circuit density(JSC) of device 3 increases by about 300% and 150% than that of device 1 and device 2,respectively;open circuit voltage(VOC) increases by about 100% and 20%.The increased solar cell performance mostly can attribute to evaporating a layer of C60 to increase the amount of paths that electrons transfer from acceptor to cathode and enlarge the area of donor acceptor interface.The other reason is that the C60 layer block the hole transfer from organics to cathode in some way.Such change in structure of solar cells improves the performance of the solar cells effectively.
Keywords:solar cells  bulk heterojunction  short-circuit current density JSC  open-circuit voltage VOC
