Degradation mechanism of organic photovoltaic devices with bathocuproine buffer layer

On the function of a bathocuproine buffer layer in organic photovoltaic cells

The role of bathocuproine BCP buffer layer inserted between active layer and Al contact in photovoltaic cells based on phthalocyanine Pc and C60 was investigated. Photoluminescence PL experiments show exciton quenching at the C60–Al interface to be strongly reduced by inserting BCP. Current-voltage characteristics of photovoltaic cells with planar geometry front electrode/ Pc/C60/BCP/Al show th...

Inverted organic photovoltaic device with a new electron transport layer

We demonstrate that there is a new solution-processed electron transport layer, lithium-doped zinc oxide (LZO), with high-performance inverted organic photovoltaic device. The device exhibits a fill factor of 68.58%, an open circuit voltage of 0.86 V, a short-circuit current density of -9.35 cm/mA2 along with 5.49% power conversion efficiency. In addition, we studied the performance of blend ra...

P-128: Inverted Top-Emitting Organic Light-Emitting Devices Using Vanadium Pentoxide as Anode Buffer Layer

Inverted top-emitting organic light-emitting devices (ITOLEDs) employing thin film of vanadium pentoxide (V2O5) capped with vacuum deposited semitransparent silver layer as top anode were studied. The devices consisted of C-545T doped in Alq3 as emitting layers exhibited a maximum external current efficiency of ~11cd/A and a turn on voltage of ~6.4V.We attribute the good performance of the devi...

New Concepts of Nano-crystalline Organic Photovoltaic Devices

The working principle of a nano-crystalline dye sensitized solar cell (nc-DSC) of the Grätzel type depends on a working cycle consisting of dye excitation, electron injection into titanium dioxide and fast reduction of the oxidized dye by a redox couple. Continuous stability testing at Solaronix on glass/glass thermoplastic sealed nc-DSC devices, revealed that no significant degradation of the ...
