Laminated fabric as top electrode for organic photovoltaics

Abstract

A simple lamination technique for conductive and semitransparent fabrics on top of organic photovoltaic cells is presented. Conductive fabrics consisted of metal wires woven in a fabric with polymeric fibers. The lamination of this conductive fabric with help of a high conductive poly(3,4- ethylenedioxythiophene) polystyrene sulfonate formulation results in well aligned low resistive metal wires as top electrode. Semitransparent flexible organic photovoltaic cells were processed with laminated fabrics as top electrode and sputtered layers of aluminum doped zinc oxide and Ag as bottom electrode. The organic photovoltaic cells showed similar performance when illuminated through the bottom or top electrode. Optical simulations were performed to investigate light scattering effects of the fabric. Results are very promising for photovoltaic and lightning devices as well as for all kinds of devices where semitransparent, highly conductive, and non-vacuum processed electrode materials are needed

Organic and perovskite solar modules innovated by adhesive top electrode and depth-resolved laser patterning

“…[24][25][26] In this context, a conductive adhesive consisting of PEDOT:PSS and sorbitol has proven to be particularly effective, but other conductive glues have been explored as well. [27][28][29][30][31][32] Organic solar cells produced using this method have shown power conversion efficiencies of up to 4% (Table S1, ESI †).…”

Ternary semitransparent organic solar cells with a laminated top electrode

“…The specific beneficial role of the combined MoO 3 /PEDOT:PSS layer in our case is interesting because PEDOT:PSS // PEDOT:PSS laminated P3HT:PCBM OSCs without MoO 3 have been demonstrated before [38,39]. When spin coating PEDOT:PSS HTL films on the photo-active layer we observed a rough surface with micrometre sized dewetting holes, while the wetting on MoO 3 (rms roughness 1.8 nm) is much better, also confirmed by the contact angle of 11° for PEDOT:PSS HTL on a MoO 3 film (data not shown).…”

Scalable Process to Develop Durable Conductive Cotton Fabric

“…Electronic textile is a rising field of research for its numerous practical applications and possible commercialization prospects. E-textiles not only provide comfort to the wearer, but also can be used as different functional applications such as organic photovoltaic (OPV) [1], wearable radiofrequency (RF)devices such as textile based-antennas and transmission line [2][3][4][5][6][7], solar cells [8,9], electromagnetic interference(EMI) shielding [10], wearable activity monitors [11], fiber-field-effect transistors [12], heat-able textiles [13,14], pressure sensors [15], electrocardiogram(ECG) [16], electromyography (EMG) [17], and electroencephalography (EEG) sensors [18], supercapacitors [19] etc. Different techniques have been introduced to impart electrical conductivity into the textile material.…”
