Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is most commonly used as an anode buffer layer in bulk-heterojunction (BHJ) polymer solar cells (PSCs). However, its hygroscopic and acidic nature contributes to the insufficient electrical conductivity, air stability and restricted photovoltaic (PV) performance for the fabricated PSCs. In this study, a new multifunctional additive, 2,3-dihydroxypyridine (DOH), has been used in the PEDOT: PSS buffer layer to obtain modified properties for PEDOT: PSS@DOH and achieve high PV performances. The electrical conductivity of PEDOT:PSS@DOH films was markedly improved compared with that of PEDOT:PSS. The PEDOT:PSS@DOH film exhibited excellent optical characteristics, appropriate work function alignment, and good surface properties in BHJ-PSCs. When a poly(3-hexylthiohpene):[6,6]-phenyl C61-butyric acid methyl ester blend system was applied as the photoactive layer, the power conversion efficiency of the resulting PSCs with PEDOT:PSS@DOH(1.0%) reached 3.49%, outperforming pristine PEDOT:PSS, exhibiting a power conversion enhancement of 20%. The device fabricated using PEDOT:PSS@DOH (1.0 wt%) also exhibited improved thermal and air stability. Our results also confirm that DOH, a basic pyridine derivative, facilitates adequate hydrogen bonding interactions with the sulfonic acid groups of PSS, induces the conformational transformation of PEDOT chains and contributes to the phase separation between PEDOT and PSS chains.

“…Simulation results showed that the electrical properties of PEDOT:PSS can have a direct impact on the power conversion efficiency (PCE) of HSCs. [ 1 ] Several schemes have been proposed to improve the electrical properties of PEDOT:PSS, such as ethylene glycol (EG), [ 2 ] dimethyl sulfoxide (DMSO), [ 3 ] N, N ‐dimethyl formamide (DMF), [ 4 ] and tetrahydrofuran (THF). [ 5 ] Another way is to increase the device's V oc by doping metal sulfide or oxide nanoparticles such as CoS [ 3 ] into the thin PEDOT:PSS films to improve its ϕ m .…”

The PEDOT: PSS/Si hybrid solar cells (HSCs) have aroused wide concern due to their many unique advantages such as simple device structure and advantages of economic processing. In this paper, The PEDOT:PSS/Si hybrid solar cells with extremely high open circuit voltage (Voc) are fabricated, We have blended novel hydroquinone (HQ) as a dopant to improve the performance of HSCs. The results show that the structure of PEDOT changes from benzoid to quinoid, and than convert back into benzoid when PEDOT have more quinoid structure, the conductivity of PEDOT: PSS films is higher. The experimental results show that when doping the hydroquinone (HQ) concentration is 2wt%, the performance of the device is the best, power conversion efficiency (PCE) is 13.12%, and VOC is 669.9mV. In addition to improving the electrical properties of PEDOT: PSS films, HQ doping retains the work function (ϕm) of pure films and achieves a high VOC of HSC, which makes it different from the modified methods employed in previous reports.This article is protected by copyright.
