Effects of different formulation PEDOT:PSS hole transport layers on photovoltaic performance of organic solar cells

Abstract

In this study, the effects of the various types of PEDOT:PSS with different conductivities on the photovoltaic parameters of organic solar cells were investigated. The performances of five various commercially available PEDOT:PSS with formulations such as FET, PT2, PH1000, PH500 and PH were compared. It was observed that the device employing PH1000 as an interlayer between ITO and the active layer exhibited the highest photovoltaic performance as compared to other devices with FET, PT2, PH500 and PH.

How varying surface wettability of different PEDOT:PSS formulations and their mixtures affects perovskite crystallization and the efficiency of inverted perovskite solar cells

“…1,14 There are different commercially available PEDOT:PSS aqueous dispersions with various grades, conductivities, and PEDOT to PSS ratios widely used as HTLs, and for organic electronic device applications. 1,14,19,20 They have different work functions, and exhibit different PEDOT to PSS ratios and viscosities, resulting in different surface roughness and conductivity. 20 It has also been stated that the work function of PEDOT:PSS lms is sensitive to the preparation conditions and storage circumstances.…”

In-depth investigation of the charge extraction efficiency for thermally annealed inverted bulk-heterojunction solar cells

“…[1][2][3][4][5] To minimize the electron extraction barrier, typically high work function materials such as calcium 6 , lithium fluoride (LiF) 7,8 or polyethyleneimine PEI 9 are used. On the other hand, low work function materials like PEDOT:PSS, 10,11 tungsten oxide (WOx) 12 or molybdenum oxide (MoOx) 13,14 have been employed to improve the hole extraction. In addition, interfacial layers can act as optical spacers to enhance the optical field of the incident light inside the photoactive layer and thus improving the generation of excitons.…”
