Photoelectric properties of heterojunctions formed from di-(pyridyl)-perylenetetracarboxylic diimide and copper phthalocyanine or pentacene

Postfabrication annealing of pentacene-based photovoltaic cells

“…8,9 Surprisingly, relatively little effort has been devoted to photovoltaic cells made from pentacene. [10][11][12][13][14] Pentacene/parylene heterojunctions, 10 and pentacene/Al Schottky junctions 14 revealed only a minor photovoltaic response. Pentacene was also used to build heterojunctions with CdS 0.6 Se 04 , 11 Si, 13 as well as a hole conductor in Grätzel-type cells.…”

Effect of buffer layers on performance of organic photovoltaic devices based on copper phthalocyanine-perylene dye heterojunction

“…He has shown that heterojunction of CuPc/perylene dye allows to obtain energy conversion efficiency approaching 1%. The next works [6][7][8][9][10][11] confirmed significant role of phthalocyanines and perylene dyes as photovoltaic materials.…”

“…It is seen that j sc (l) is symbatic with respect to the absorption spectrum of MePTCDI and rather antibatic with respect to the absorption spectrum of CuPc. Such shape of j sc (l) at illumination through ITO indicates that charge carrier photogeneration takes place at the nearest vicinity of phthalocyaninne/perylene dye interface [2][3][4][5][6][7][8][9][10].…”

The photovoltaic effect in a heterojunction of molybdenyl phthalocyanine and perylene dye

“…The same process of charge-carrier photogeneration occurs in heterojunctions formed from other phthalocyanines (e.g. copper or zinc phthalocyanine) and perylene dye [1][2][3][4][5][6][7][17][18][19]. Perfect correlation between the U oc and absorption spectra is not expected since the distribution of light intensity (and consequently the exciton distribution) in a multi-layer system can also be determined by reflecting the electromagnetic wave at each interface and interference effect [3,18,[20][21][22].…”

“…Organic heterojunctions formed from phthalocyanine and perylene dye have been the subject of intensive investigations due to their likely application in thin-film photovoltaic cells [1][2][3][4][5]. A great number of phthalocyanines and perylene dyes enable one to obtain many various heterojunctions, in which phthalocyanine is a p-type semiconductor and the perylene dye -an n-type material.…”
