Book Description
The operation of everything in the universe needs a special „material“-energy. The earth is no exception. There are many kinds of energy sources on earth. But where does the earth‘s energy come from? The answer is that everything grows under the sun. Developing renewable energy is of strategic importance to achieve sustainable energy supply. Simulating natural photosynthesis is the ultimate goal of effi cient solar energy conversion. Photovoltaic technology has been widely used in industry and will be one of the major energy sources in the future. Developing new materials and structures, the photoelectric conversion effi ciency of solar cells will be improved day by day, and solar cells will attract more and more attention. This book presents principles of solar photovoltaic conversion, and introduces the physical and chemical processes involved. Mechanisms which affect solar cell performance are also discussed.

Book Description
Dye-sensitized solar cells (DSCs) are among the promising photovoltaic technologies that could potentially replace the expensive silicon. Liquid electrolyte-based DSCs have the highest efficiency but they suffer from potential stability and encapsulation problems when manufactured at high volumes. Research groups are actively pursuing solid state dye-sensitized solar cells (ss-DSCs), which uses a solid-state hole-transport material to replace the liquid electrolyte. SS-DSCs can potentially achieve higher power conversion efficiencies than the liquid-electrolyte because the open-circuit voltage can be adjusted by the choice of different hole-transport materials. However, current ss-DSCs are limited by both pore filling and electron-hole recombination such that the optimal thickness is around 2 microns, far thinner than the thickness needed to achieve good optical absorption. This thesis presents results that address two challenges facing the field of ss-DSC research - what is limiting the thickness of the device, and what can we do to boost light absorption and power conversion efficiency? In the first part, we describe how pore filling of hole-transport materials inside mesoporous TiO2 films is a limiting factor to the device thickness. This is accomplished by three closely-related pore filling projects: (a) quantifying the pore filling of hole-transport materials inside mesoporous TiO2 films; (b) experimenting with new methods to improve pore filling fraction; and (c) investigating the effect of pore filling on photovoltaic performances of ss-DSCs and the underlying photophysical mechanisms. This brings new physical understanding of the importance of pore filling and how pore filling a effects the photovoltaic performances. In the second part, we describe a new device architecture to increase the absorption through the use of plasmonic back reectors, which consist of two-dimensional (2D) array of silver nanodomes. They are incorporated into the ss-DSCs by nanoimprint lithography, and they enhance absorption through excitation of plasmonic modes and increased light scattering.

Book Description
The book provides an explanation of the operation of photovoltaic devices from a broad perspective that embraces a variety of materials concepts, from nanostructured and highly disordered organic materials, to highly efficient devices such as the lead halide perovskite solar cells. The book establishes from the beginning a simple but very rich model of a solar cell, in order to develop and understand step by step the photovoltaic operation according to fundamental physical properties and constraints. It emphasizes the aspects pertaining to the functioning of a solar cell and the determination of limiting efficiencies of energy conversion. The final chapters of the book establish a more refined and realistic treatment of the many factors that determine the actual performance of experimental devices: transport gradients, interfacial recombination, optical losses and so forth. The book finishes with a short review of additional important aspects of solar energy conversion, such as the photonic aspects of spectral modification, and the direct conversion of solar photons to chemical fuel via electrochemical reactions.
