1. 1. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques

   University essay from Uppsala universitet/Fasta tillståndets fysik

   Author : Ronja Olsmats Baumeister; Evelina Roxner; [2022]
   Keywords : EDMR; EPR; trEDMR; PEDOT:PSS; PCBM; P3HT; organic solar cells; osc; opv;

   Abstract : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

3. 2. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Jonatan Fast; [2017]
   Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

   Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

4. 3. Identification of green solvents for organic solar cells using P3HT and PC60BM

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Author : Ruud Vanhecke; [2015]
   Keywords : Organic solar cells; P3HT; PC60BM; Hansen solubility parameters;

   Abstract : The importance of renewable energy sources is becoming clearer and clearer as unsustainable energy sources are running out and global warming is getting worse. Energy derived from sunlight is already commonly used, but more energy can be produced from sunlight when solar cells become cheaper. READ MORE

6. 5. Measuring the efficiency and charge carrier mobility of organic solar cells

   University essay from Institutionen för fysik

   Author : ABASI ABUDULIMU; [2012]
   Keywords : Solar cells; P3HT; PCBM; shourt circuit current; open circuit voltage; maximum power; fill factor; efficiency; charge carrier mobility; CELIV; DI-SCLC;

   Abstract : P3HT single layer, P3HT/PCBM bilayer and P3HT/PCBM inverted bilayer devices were produced by spin coating organic layers onto ITO patterned glass in air, and clamping it with an Au coated silicon wafer, as top electrode, at the end (Figure13). Normal and inverted bilayer devices were also fabricated with and without PEDOT:PSS. READ MORE
