    • The present invention relates to an improved process for the isolation of high-purity lignin from an organosolv liquor. In a preferred embodiment, the invention also concerns the production of a light-coloured lignin and the thus produced lignin. The process according to the invention comprises (a) precipitating lignin from the liquor; (b) separating the precipitated lignin from the liquor; (c) heating the separated lignin until it undergoes a phase separation by expelling moisture to obtain partly-dried lignin and a liquid phase; (d) separating the partly-dried lignin from the liquid phase; and (e) drying the separated partly-dried lignin to obtain the isolated lignin. Isolated lignins obtained as such have increased purity and reduced colour intensity, compared to lignins isolated via conventional techniques. The lignin according to the invention is white, off-white or beige in colour and has a molar mass M w of 1000 –10000 g/mol determined using alkaline size exclusion chromatography (SEC) and has a high purity with a sulphur content of at most 1 wt% and typically a residual carbohydrate content of at most 5 wt%. Such light-coloured lignins are unprecedented in the art and a marked improvement in view of potential application of lignin in especially performance products.
    • 本发明涉及从有机溶液中分离高纯度木质素的改进方法。 在一个优选的实施方案中,本发明还涉及生产浅色木质素和由此生产的木质素。 根据本发明的方法包括(a)从液体中沉淀木质素; (b)从液体中分离沉淀的木质素; (c)加热分离的木质素,直到其通过排出水分进行相分离以获得部分干燥的木质素和液相; (d)从液相中分离部分干燥的木质素; 和(e)干燥分离的部分干燥的木质素以获得分离的木质素。 与通过常规技术分离的木质素相比,如此获得的分离的木质素具有增加的纯度和降低的颜色强度。 根据本发明的木质素为白色,灰白色或米色,其摩尔质量M w为1000-10000g / m 2, mol使用碱性尺寸排阻色谱法(SEC)测定并且具有至多1wt%的硫含量和通常至多5wt%的残余碳水化合物含量的高纯度。 这种浅色木质素在本领域是前所未有的,并且鉴于木质素在特别是性能产品中的潜在应用的显着改进。

    • Method of making an array of interconnected solar cells, including a) providing a continuous layer stack (1) of a prescribed thickness on a substrate (8), the layer stack (1) including an upper (2) and a lower (3) conductive layer having a photoactive layer (4) and a semiconducting electron transport layer (6) interposed there between; b) selectively removing the upper conductive layer (2) and the photoactive layer (4) for obtaining a contact hole (10) exposing the semiconducting electron transport layer (6); c) selectively heating the layer stack (1) to a first depth ( dl ) for obtaining a first heat affected zone (12) at a first centre-to-centre distance ( sl ) from the contact hole (10), the first heat affected zone (12) being transformed into a substantially insulating region with substantially the first depth ( dl ) in the layer stack, thereby locally providing an increased electrical resistivity to the layer stack (1).
