“…With the objective of increasing the efficiency of thermoelectric materials, attempts have been made to increase the ZT value. For most recently developed materials, however, the figure of merit (FOM) has been less than 2 [33]. It has long been recognized that new materials are key to improving the FOM.…”

Energy harvesting refers to the set of processes by which useful energy is captured from waste, environmental, or mechanical sources and is converted into a usable form. The discipline of energy harvesting is a broad topic that includes established methods and materials such as photovoltaics and thermoelectrics, as well as more recent technologies that convert mechanical energy, magnetic energy and waste heat to electricity. This article will review various state-of-the-art materials and devices for direct energy conversion and in particular will include multistep energy conversion approaches. The article will highlight the nano-materials science underlying energy harvesting principles and devices, but also include more traditional bulk processes and devices as appropriate and synergistic. Emphasis is placed on device-design innovations that lead to higher efficiency energy harvesting or conversion technologies ranging from the cm/mm-scale down to MEMS/NEMS (micro- and nano-electromechanical systems) devices. Theoretical studies are reviewed, which address transport properties, crystal chemistry, thermodynamic analysis, energy transfer, system efficiency and device operation. New developments in experimental methods; device design and fabrication; nanostructured materials fabrication; materials properties; and device performance measurement techniques are discussed.

“…In recent years there have been done developments on airships, with the resurgence of these vehicles as a viable alternative of multipurpose platforms [35,36]. Several models and studies regarding the application of PV technology to airships were developed by [37][38][39][40][41][42][43]. These models can be extrapolated to the analysis of non-stratospheric aircrafts, such as radiation models [41], thermal behavior of the solar panels models [42], design and management of hybrid systems models, among others.…”

“…James et al [37] propose the use of a combined system of photovoltaic cells and fuel cells. Choi et al [38] refer to the possibility of using other options such as advanced systems thermoelectric energy conversion (ATE) and nano materials solar energy collection, designed by NASA Langley Research Center. They show an approach to calculate the solar energy incident on the airship.…”

a b s t r a c tThis paper presents the analysis of the technical feasibility to use a photovoltaic system to supply the electrical demand on two referential commercial aircraft, Airbus A340-300 and Cessna Conquest 441. The methodology approach comprises a process given by the selection of the photovoltaic technology, the calculation of the available solar radiation, the determination of the electrical demand, the layout definition of solar cells, the photovoltaic system capacity calculation, the estimation of the photovoltaic system weight, the estimation of fuel savings for photovoltaic system equipped aircrafts, and finally, the extrapolation of results to other aircrafts. The study concludes that the use of photovoltaic technology to supply power to the aircraft electrical system can result viable from the point of view of operational profitability, generating savings in fuel consumption. These fuel savings depend on the type of aircraft, the flying route and schedules of operation.
