ABSTRACTNonadiabatic energy dissipation by electron subsystem of nanostructured solids unveil interesting opportunities for the solid-state energy conversion and sensor applications. We found that planar Pd/n-SiC, Pt/n-GaP and Pd/n-GaP Schottky structures with nanometer thickness metallization demonstrates a nonadiabatic channel for the conversion into electricity the energy of a catalytic hydrogen-to-water oxidation process on the metal layer surface. The observed abovethermal current greatly complements the usual thermionic emission current, and its magnitude is linearly proportional to the rate of formation and desorption of product water molecules from the nanostructure surface. The possibilities and advantages of utilizing the nonadiabatic functionality in a novel class of chemical-to-electrical energy conversion devices are discussed. The technology has a potential for a very high volumetric energy density due to the intrinsically planar device architecture.

The sustainable development of clean and efficient electricity generation techniques accelerated the research for invention of alternative electricity generation methods. In this chapter, the conceptual analysis of newly invented photon-enhanced thermionic emission (PETE) energy conversion process has been presented. It is a promising option for harvesting solar energy in terms of capturing photon as well as thermal energy simultaneously and converting solar energy into electrical energy based on photovoltaic and thermionic emission processes of energy conversion. Thus, the PETE process utilizes photons for PV conversion and heat of radiation for thermionic emission process. The main objective of this chapter is to review and analyze the performance of PETE converters including thermal modeling, choice of materials, and parametric optimization. The appropriate choice of material requirements for cathode and anode of PETE converters is necessary for practical design of PETE converters. The PETE converter may be an efficient future option for electricity generation using solar energy.

Among the various forms of natural energies, heat is the most prevalent and least harvested energy. Scavenging and detecting stray thermal energy for conversion into electrical energy can provide a cost-effective and reliable energy source for modern electrical appliances and sensor applications. Along with this, flexible devices have attracted considerable attention in scientific and industrial communities as wearable and implantable harvesters in addition to traditional thermal sensor applications. This review mainly discusses thermal energy conversion through pyroelectric phenomena in various lead-free as well as lead-based ceramics and polymers for flexible pyroelectric energy harvesting and sensor applications. The corresponding thermodynamic heat cycles and figures of merit of the pyroelectric materials for energy harvesting and heat sensing applications are also briefly discussed. Moreover, this study provides guidance on designing pyroelectric materials for flexible pyroelectric and hybrid energy harvesting.
