Book excerpt: While the protection offered by BH dyes affords photocathodes with long-term stability and high photocurrents in low pH aqueous conditions, p-DSPEC devices sensitized with BH4 have achieved less than ideal faradaic efficiencies attributed to catalyst decomposition. Thus, another new dye, cat-i, was designed and synthesized, featuring a pyridine moiety, which gives rise to the formation of a stable dye-catalyst supramolecule via axial coordination of the dye to the Co center of a well-known water reduction catalyst, Co(dmgBF2)2. Further, this dye-catalyst complexation could facilitate electron transfer from the photoexcited dye to the cobaloxime catalyst. When used as a sensitizer in a p-DSPEC device, the cat-i-cobaloxime complex exhibits significantly higher photocurrents than cat-i alone and produces H2 with 87% Faradaic efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Chapter 3 exploits the unique highly hydrophobic and large light absorption properties of the BH4 dye to answer the stability and wettability issues faced in solar driven water splitting applications. The unprecedented stability of the BH4 dye on NiO allowed the first use of low pH electrolytes to be used in p-type water splitting DSPECs. The ability to use acidic electrolytes likewise allowed the use of an acidically soluble and active earth abundant [Mo3S4]4+ homogeneous catalyst for the first time. Chapter 4 further utilizes the aqueous stability of the BH series dyes for aqueous based DSSCs. Utilizing water as the electrolyte solvent makes the already cost effective tandem DSSCs even more economical and environmentally friendly. The BH2 dye was used to fabricate entirely aqueous p-type DSSCs using the iodide/triiodide redox for the first time. The BH2 dye displayed aqueous p-type DSSC photocurrents greater than most non-aqueous p-type DSSCs and were stable for up to 4 months with no sign of photocathode degradation. Furthermore, aqueous tandem DSSC were fabricated with a completely aqueous electrolyte with all earth abundant materials with no use of any precious metals. Chapter 5 introduces a new dye (KC2) designed specifically for aqueous based dye sensitized electrodes. From what was learned in Chapters 2 – 4, there exists a dilemma between aqueous dye stability and wettability in the form of hydrophobicity. A novel layered amphiphilic structure is proposed to balance both the aqueous stability and wettability of dye sensitized films. The new amphiphilic KC2 dye was synthesized and fully characterized. It was compared to its purely hydrophobic analog (BH2) in all aspects including electrochemical, photo-physical and device performance properties. The KC2 dye doubles the aqueous wettability of sensitized NiO films and displays excellent stability identical to that of the hydrophobic BH2 dye. Finally from what was discovered from the KC2 dye, a new amphiphilic structure is proposed for further exploration. Chapter 6 summarizes the common experimental procedures and details used throughout the dissertation. More specific procedures relevant to each chapter are discussed in each corresponding chapter introduction.

Book excerpt: This book covers in a textbook-like fashion the basics or organic solar cells, addressing the limits of photovoltaic energy conversion and giving a well-illustrated introduction to molecular electronics with focus on the working principle and characterization of organic solar cells. Further chapters based on the author’s dissertation focus on the electrical processes in organic solar cells by presenting a detailed drift-diffusion approach to describe exciton separation and charge-carrier transport and extraction. The results, although elaborated on small-molecule solar cells and with focus on the zinc phthalocyanine: C60 material system, are of general nature. They propose and demonstrate experimental approaches for getting a deeper understanding of the dominating processes in amorphous thin-film based solar cells in general. The main focus is on the interpretation of the current-voltage characteristics (J-V curve). This very standard measurement technique for a solar cell reflects the electrical processes in the device. Comparing experimental to simulation data, the author discusses the reasons for S-Shaped J-V curves, the role of charge carrier mobilities and energy barriers at interfaces, the dominating recombination mechanisms, the charge carrier generation profile, and other efficiency-limiting processes in organic solar cells. The book concludes with an illustrative guideline on how to identify reasons for changes in the J-V curve. This book is a suitable introduction for students in engineering, physics, material science, and chemistry starting in the field of organic or hybrid thin-film photovoltaics. It is just as valuable for professionals and experimentalists who analyze solar cell devices.

Available in PDF, EPUB and Kindle. Book excerpt: With the increasing world-energy demand there is a growing necessity for clean and renewable energy. The sun being one of the most abundant potential sources accounts for less than 1% of the global energy supply. The market for solar cells is one of the most strongly increasing markets, even though the prize of conventional solar cells is still quite high. New emerging technologies, such as organic and hybrid solar cells have the potential to decrease the price of solar energy drastically. This book offers an introduction to these new types of solar cells and discusses fabrication, different architectures and their device physics on the bases of the author's teaching course on a master degree level. A comparison with conventional solar cells will be given and the specialties of organic solar cells emphasized.
