Digital printing of a novel electrode for stable flexible organic solar cells with a power conversion efficiency of 8.5.

Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) mixed with single-wall nanotubes (SWNTs) (10:1) and doped with (0.1 M) perchloric acid (HClO) in a solution-processed film, working as an excellent thin transparent conducting film (TCF) in organic solar cells, was investigated. This new electrode structure can be an outstanding substitute for conventional indium tin oxide (ITO) for applications in flexible solar cells due to the potential of attaining high transparency with enhanced conductivity, good flexibility, and good durability via a low-cost process over a large area.

Return to judo after joint replacement.

Purpose: The main purpose of this study was to investigate whether judo could be practised after joint replacement.

Methods: Two hundred and twelve questionnaires were sent to Judokas licensed at the French Judo Federation, over the age of 60, with at least a black belt 6th Dan. Out of 83 responses, 38 individuals, mean age 72.
