[1] Bifacial ifo/(n+pp+)cz-si/ito silicon solar cell with advanced ag-free multi-wire metallization attached to tco layers by transparent conductive paes copolymers / A. B. Chebotareva, G. G. Untila, T. N. Kost et al. // Solar Energy. — 2018. — Vol. 164. — P. 292–300. Multi-wire metallization and interconnection for silicon solar cells is considered as a revolutionary technology for the next generation of photovoltaic modules, since it drastically reduces their cost while boosting efficiency. Here, we describe the synthesis, properties and application of transparent conductive polymer films, poly(arylene ether sulfone) copolymers (co-PAESs), for attaching the wires to solar cells with transparent conductive oxide (TCO) layers. We have synthesized a number of thermoplastics with the fraction of fluorene-containing units q=3, 5, 10, 15, and 50 mol%. Increasing q has been shown to change the glass transition temperature of the copolymers from 186 to 232 oC, their 100% strain temperature from 240 to 320 oC, their optical band gap from 3.80 to 3.77 eV, and their refractive index from 1.554 to 1.586. At that, absorption in the wavelength range 370–1100 nm is negligible, the resistivity and the peel strength of wire/co-PAES/TCO (TCO: ITO=In2O3:Sn and IFO=In2O3:F) contacts lies within 0.43–2.7mΩ cm2 and 2.7–3.0 N/mm, respectively. The co-PAES film with q=10 mol% was successfully used to attach wire contact grid in bifacial IFO/(n+pp+)Cz-Si/ITO solar cell, which showed a front/rear efficiency of 18.2%/15.1% under 1 sun illumination.
