Low-Cost upscaling compatibility of five different ITO-Free architectures for polymer solar cells

Voltage-controlled surface wrinkling of elastomeric coatings

Wrinkling of elastomeric coatings by an electric field is reported. The associated changes in the coating's optical properties yield switchable mirrors and windows. The field Ec needed to induce wrinkling is a factor of 4.4 lower than the theoretically predicted value, which is attributed to space-charge injection. Copyright © 2013 WILEY-VCH...

Inkjet printing technology for OPV applications

Large-scale production of organic photovoltaics (OPVs) at low cost is, still, a future concept thought to promote the market share of solar energy. Working towards the roll-to-roll production of OPVs, different compatible deposition techniques are investigated. Inkjet printing is a promising candidate, as it allows the contact-free deposition of...

Inkjet technology for large-area OPV applications

The roll-to-roll manufacturing process is believed to significantly reduce the cost-price of large area organic photovoltaic systems. Therefore, we build up knowledge base concerning the influence of process conditions on the performance of polymer solar cells. Inkjet printing has been a major research in processing photoactive materials because...

Sensitization of p-type NiO using n-type conducting polymers

We report on the sensitization of a p-type inorganic semiconductor, NiO, by n-type conjugated polymers. NiO thin films were deposited using RF sputtering in pure Ar (NiO A) or in Ar + O₂ (90% + 10%) (NiO B). XPS and Kelvin probe measurements indicate the incorporation of oxygen in NiO B leading to the formation of electron-accepting...
