“…The usage of the electrospray deposition (ESD) made possible the uniform coating, although the film deposition rate was very slow of 0.2 nm/s. 4 Simple coating technique with high film uniformity, therefore, is strongly required on hydrophobic c-Si wafer. Recently, Vosgueritchian et al revealed that the Zonly fluorosurfactant-treated PEDOT:PSS film showed lower sheet resistance compared to untreated films, and it is a possible material for indium tin oxide (ITO)-free organic photovoltaics as stretchable and flexible transparent electrodes.…”

We demonstrate a highly efficient hybrid crystalline silicon (c-Si) based photovoltaic devices with hole-transporting transparent conductive poly-(3,4-ethlenedioxythiophene):poly(styrenesufonic acid) (PEDOT:PSS) films, incorporating a Zonyl fluorosurfactant as an additive, compared to non additive devices. The usage of a 0.1% Zonly treated PEDOT:PSS improved the adhesion of precursor solution on hydrophobic c-Si wafer without any oxidation process. The average power conversion efficiency η value was 10.8%-11.3%, which was superior to those of non-treated devices. Consequently, c-Si/Zonyl-treated PEDOT:PSS heterojunction devices exhibited the highest η of 11.34%. The Zonyl-treated soluble PEDOT:PSS composite is promising as a hole-transporting transparent conducting layer for c-Si/organic photovoltaic applications.

“…Several attempts have been made for the uniform deposition of PEDOT:PSS on the textured c-Si substrate by several deposition techniques such as SC with surfactant additive, 11) screen printing, 12) ink-jet printing, electrospray deposition (ESD), [13][14][15][16][17] and chemical mist deposition (CMD). [18][19][20][21][22][23][24] Among several deposition techniques, gas-phase deposition is a possible candidate for the uniform deposition of organic materials on textured Si substrates. However, few studies have been performed on the deposition of organic materials by gas-phase deposition and their growth kinetics.…”

Chemical mist deposition (CMD) of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) was investigated in terms of cavitation frequency f, solvent, flow rate of nitrogen, substrate temperature T s, and substrate dc bias V s as variables for efficient PEDOT:PSS/crystalline silicon (c-Si) heterojunction solar cells. The high-speed-camera and differential mobility analysis characterizations revealed that the average size and flux of PEDOT:PSS mist depend on f, type of solvent, and V s. Film deposition occurred when positive V s was applied to the c-Si substrate at T s of 30–40 °C, whereas no deposition of films occurred with negative V s, implying that the film is deposited mainly from negatively charged mist. The uniform deposition of PEDOT:PSS films occurred on textured c-Si(100) substrates by adjusting T s and V s. The adhesion of CMD PEDOT:PSS film to c-Si was greatly enhanced by applying substrate dc bias V s compared with that of spin-coated film. The CMD PEDOT:PSS/c-Si heterojunction solar cell devices on textured c-Si(100) in 2 × 2 cm2 exhibited a power conversion efficiency η of 11.0% with better uniformity of the solar cell parameters. Furthermore, η was increased to 12.5% by adding an AR coating layer of molybdenum oxide MoO x formed by CMD. These findings suggest that CMD with negatively charged mist has great potential for the uniform deposition of organic and inorganic materials on textured c-Si substrates by suitably adjusting T s and V s.
