This book explores why the properties of liquid crystals make them ideal for use in photovoltaic applications. It achieves this by presenting a description of the properties of liquid crystals and how their electronic properties compare to that of polymers used in organic photovoltaics. It explores how the type of liquid crystal chosen can help in improving the efficiency of the photovoltaics. It compares experimental and theoretical ways in which the efficiency is directly or indirectly estimated between the organic photovoltaics and the organic photovoltaics that contain a liquid crystal. It first introduces liquid crystals and their different varieties, before reviewing their electronic transfer properties and how they can improve efficiency. It is an ideal text for graduate students and young researches considering entering the area of photovoltaics - specifically, organic photovoltaics – who do not yet have knowledge of this field.

    • Introduces the field of liquid crystals and provides basic information to those new to the field, in a concise and visual manner

    • Describes which characteristics of a liquid crystal are most advantageous to use in photovoltaics

    • Provides basic knowledge of photovoltaics for those who do not have previous knowledge of how they behave electronically
