Abstract
Photovoltaic cells disclosed comprising a structure according to formula I as shown below: wherein R1, R4, R8, R11, R15, R18, R22, and R25 are selected from the group consisting of hydrogen, fluorine, chlorine, methoxy, methyl, ethyl and cyano; wherein R31 and R29 are both hydrogen or together are a metal ion having a double positive charge or a metal ion plus non-metal atom or group bound to the metal ion, and having overall a double positive charge; and wherein R1, R4, R15, and R18 are the same and are a first substituent, and R8, R11, R22 and R25 are the same and are a second substituent which is different from said first substituent.
Claims19
A photovoltaic cell comprising a phthalocyanine layer comprising a compound of formula (I):
- wherein
- R2, R3, R9, R10, R16, R17, R23 and R24 are hydrogen;
- R1, R4, R8, R11, R15, R18, R22 and R25 are selected from the group consisting of hydrogen, fluorine, chlorine, methoxy, methyl, ethyl and cyano;
- R29 and R31 are both hydrogen or together are a metal ion having a single valence or a metal ion and non-metal ion or group bound to the metal ion;
- and
- R1, R4, R15, and R18 are the same, and are a first substituent, and R8, R11, R22, and R25 are the same and are a second substituent which is different from said first substituent;
- and a metallic conductive layer disposed in contact with said phthalocyanine layer to form a matched contact with a minimal resistance.
A photovoltaic cell comprising
- a first layer comprising indium tin oxide;
- a second layer comprising a compound selected from the group consisting of a perylene derivative, ZnC32F16N8, and a metallophthalocyanine comprising a core atom selected from the group consisting of M++, M++═O and M++—Cl wherein M represents a metal ion or a metal ion plus non-metal atom or group bound to the metal ion;
- said second layer disposed in contact with said first layer;
- a third layer comprising a compound of formula (I) below in crystalline form, said third layer disposed in contact with said second layer;
- wherein
- R2, R3, R9, R10, R16, R17, R23 and R24 are hydrogen;
- R1, R4, R8, R11, R15, R18, R22 and R25 are selected from the group consisting of hydrogen, fluorine, chlorine, methoxy, methyl, ethyl and cyano;
- R29 and R31 are both hydrogen or together are a metal ion having a single valence or a metal ion and non-metal ion or group bound to the metal ion;
- and
- R1, R4, R15, and R18 are the same, and are a first substituent, and R8, R11, R22, and R25 are the same and are a second substituent which is different from said first substituent;
- and
- a fourth metallic conductive layer, said fourth layer disposed in contact with said third layer, wherein said third and fourth layers form a matched contact with a minimal resistance.
