1. 1. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

   Kandidat-uppsats,

   Författare :Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
   Nyckelord :Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

   Sammanfattning : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. LÄS MER

3. 2. Synthesis and assembly of biodegradable/ compatiblegraft copolymers for biomedical applications

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för kemi - Ångström

   Författare :Kristina Nilsson; [2011]
   Nyckelord :;

   Sammanfattning : The synthesis and characterization  of nanostructured block copolymers is described.Block copolymers were grafted onto a backbone polymer  that consists of themonomer  MTC-BuOBn.  The block copolymers have a part consisting of PTMC(trimethylene  carbonate) and a part consisting of PLLA.
