Coatings organic solar cells

ITO/PEDOT PSS/CuPc C6o/Mg/Ag organic solar cells were fabricated on ITO (5 Q/squarc sheet resistance)-coated glass substrates. After solvent cleaning, the ITO/glass substrates were spin-coated by a PEDOT PSS layer and immediately transferred into the deposition chamber. A 70 nm-thick CuPc C60 blend layer was prepared by organic vapour phase deposition (OVPD ) [2, 3], The Mg/Ag back contacts were deposited by thermal evaporation in high vacuum (p 10 7 mbar) on non-air-exposed absorber surfaces. The device preparation details can be found elsewhere [4], The compositional and substrate temperature (Tsubstrate) investigations are carried out on type A and B devices with nonoptimised and optimised contacts, respectively. 

The past decades have seen a rapid expansion in the use of polymers in many new fields of applications where they play an essential role. Unfortunately, most polymers are not inherently stable to light, so the studies of their photochemical behavior remain a subject of constant interest. Among the various fields that were the object of interest in the last few years, one has observed some of them emerging as the domains of organic solar cells, of coatings, and of nanocomposites. 

A PEN-based ultra-high barrier material, which is entirely fabricated by PECVD, has been introduced as a coating material for flexible organic solar cells [92]. As encapsulation films, PEN substrates were preferred to PET because of the higher temperature of glass transition.

The fabrication technique of active layer (electron donor and electron acceptor) also affects the properties and PCE of the fabricated organic solar cells. Thin film of active layer can be prepared by spin coating, solution printing, roll-to-roll, spray coating, etc. In this contribution, fabrications of nanofibers by electrospinning to control the morphology of semiconductor materials and the uses of electrospun nanofibers as active layers or other parts of organic solar cells will be later reviewed.

On the other hand, polymers 89a and b were obtained in high yields and high My, (66000 and 70000, respectively) [75]. Polymer 89a was blended together with MDMO-PPV and spin-coated to prepare organic solar cells. However,...
