“…Several types of fuels are used or tested but the most common is hydrogen with oxygen playing the role of the oxidant. The major disadvantage is still the very high cost of fuel cells, which is unmatchable by the conventional fuels despite the significant decrease being achieved during the last decade (Boudghene-Stambouli and Traversa, 2002). Should their cost become competitive to other energy sources, they could constitute a powerful solution to the GHG emissions, although the disposal of the used cells made from precious but toxic metals (platinum, palladium) would also be an issue of environmental concern.…”

“…Over the last several decades there have been extensive efforts in research and development to establish renewable energy sources, such as earthabundant biomass [3], hydrogen [4][5], solar power [6] and so on. Various systems have been proposed to efficiently utilize the energies via electro-or chemical reactions [7].…”

Design of novel materials in renewable energy systems plays a key role in powering transportation vehicles and portable electronics. This review introduces the research work of first principles-based computational design for the materials over the last decade to accomplish the goal with less financial and temporal cost beyond the conventional approach, especially, focusing on electrocatalyst toward a proton exchange membrane fuel cell (PEMFC). It is proposed that the new method combined with experimental validation, can provide fundamental descriptors and mechanical understanding for optimal efficiency control of a whole system. Advancing these methods can even realize a computational platform of the materials genome, which can substantially reduce the time period from discovery to commercialization into markets of new materials.

“…The solar cells based on copper oxide and zinc oxide are a promising alternative to conventional silicon cells because of the relatively low cost of production and theoretical efficiency of ≈16% [1][2][3][4][5][6][7][8][9]. This paper focuses on the characteristics of the ZnO layer -n-type, and Cu 2 O/CuO -p-type semiconductors prepared by using a method of electrodeposition, which allows to create transparent semiconductor layers with good optoelectronic properties [4].…”

The aim of this research was to fabricate zinc oxide/cuprous(I) oxide-based heterojunction solar cells with the use of electrodeposition methods, and further to investigate their structures and photovoltaic properties. The ZnO and Cu2O were used as n-and p-type semiconductors, respectively, to fabricate photovoltaic devices based on Ag/ZnO/Cu2O/Cu(100) heterojunction structures. The crystallite sizes of ZnO and Cu2O were determined to be 25.4(3) nm and 69.8(6) nm, respectively. It was pointed out that efficiencies of the solar cells can be gradually adjusted, using different thicknesses of Cu2O layers, to achieve values as high as 2.7%. The standard diode model and high device performance provide new insights into the issue, outlining guidelines for high-performance solar cells and suggesting that a metal-n-type semiconductor-p-type semiconductor nanostructure-crystal layered, sandwiched-type architecture is a promising platform to boost the efficiency.
