Materials for type III solar cells have branched into a series of generic groups. These include organic ‘small molecule’ and polymer conjugated structures; fullerenes; copper indium gallium selenide nanocrystal films; quantum dots; hybrid organic/inorganic composites; dyes/TiO2 for Grätzel cells; and perovskites. Whilst the power conversion efficiencies of organic solar cells are modest compared to other type III photovoltaic materials; plastic semiconductors provide a cheap route to manufacture through solution processing and offer flexible devices. However; other types of materials are proving to be compatible with this type of processing whilst providing higher device efficiencies. As a result; the field is experiencing healthy competition between technologies that are pushing progress at a very fast rate. In particular; perovskite solar cells have emerged very recently as a highly disruptive technology with power conversion efficiencies now over 20%. Perovskite cells; however; still have to address environmental and stability issues. With such a diverse range of materials; it is timely to capture the different technologies into a single volume of work. This ebook will give a collective insight into the different roles that nanostructured materials play in type III solar cells. This will be an essential textbook for those working with any of the devices highlighted above; providing a fundamental understanding and appreciation of the potential and challenges associated with each of these technologies.
