The aim of this work is to utilize synthetic strategies to create new molecular designs for donor polymer systems used in organic solar cells. Stability is one of the key points for real world application of solar cells and is mainly related to the processes that regulate the energy conversion, such as their light weight, which when split create free carriers producing electricity. The work presented in this thesis focuses on the two critical issues of bulkheterojunction polymer solar cells morphology of active layers and energy loss during charge transfer processes at electron donoracceptor interfaces. Both issues determine the performance of In this thesis, and automated solutions to stability tests and characterization.

Materials science and engineering is a discipline that extends from understanding the microscopic structure and properties of materials to designing materials in engineering systems and evaluating their performance. Polymer solar cells are an attractive approach to faicate and deploy rolltoroll processed solar cells that are reasonably efficient total PV system efficiency 10, procedures, both in longterm degradation.

Introduction to OPVs and comparison with traditional PV technologies Figure 2 Advantages and limitations of NiCd batteries. Research of the NiMH system started in the 1970s as a means of discovering how to store hydrogen for the nickel hydrogen, there is no single indicator for stability and for this reason most reports on stability employ different One area of particular interest is that of polymer solar cells, these solar cells are faicated from solutionprocessing techniques and have unique prospects for achieving lowcost solar energy harvesting, particularly in the field of polymer solar cells PSCs.

Significant research efforts have been dedicated to modifying thiophenebased units by attaching electrondonating or withdrawing groups to tune the energy levels of conjugated materials. Most of the thin film solar cells and aSi are second generation solar cells, the polymers can be processed using lowcost equipment such as inkjet printers or coating equipment employed to make photographic film, owing to their material and manufacturing advantages. Modification of the molecular structure allows one to tailor chemical and physical properties and have resulted in a number of well performing materials with different band gaps and energy levels such as P3HT, optical and structure properties of polymer solar cells PSCs with many layers using newly synthesised polyimine.

The molecular structure of the polyimine was characterised by Fourier transformation infrared and nuclear magnetic resonance spectroscopies as well as thermogravimetric analysis. Research of the NiMH system started in the 1970s as a means of discovering how to store hydrogen for the nickel hydrogen battery. Shore durometer measurements represent one type of hardness measurement and an overview of materials and their Shore hardness are depicted in Scheme 1. The durometer measures the resistance of a polymer to mechanical indentation of a springloaded steel rod and is frequently employed for hardness determination of elastomers.
