“…In order to meet these goals we developed a data mining workflow and applied it to two libraries differing in their MO composition and method of preparation, namely, a TiO 2 |CuO library reported by Anderson et al 4. and a TiO 2 |Cu 2 O library reported by Pavan et al 11. We demonstrate that the workflow is able to highlight those material descriptors which most affect PV properties and to develop models with good predictive statistics for several PV properties measured on the two input libraries.…”

Growth in energy demands, coupled with the need for clean energy, are likely to make solar cells an important part of future energy resources. In particular, cells entirely made of metal oxides (MOs) have the potential to provide clean and affordable energy if their power conversion efficiencies are improved. Such improvements require the development of new MOs which could benefit from combining combinatorial material sciences for producing solar cells libraries with data mining tools to direct synthesis efforts. In this work we developed a data mining workflow and applied it to the analysis of two recently reported solar cell libraries based on Titanium and Copper oxides. Our results demonstrate that QSAR models with good prediction statistics for multiple solar cells properties could be developed and that these models highlight important factors affecting these properties in accord with experimental findings. The resulting models are therefore suitable for designing better solar cells.

“…: The TiO 2 thin fi lm layer was deposited by a home-built spray pyrolysis system [ 31 ] on a commercially available fl uorine doped tin oxide (FTO) coated glass substrate, TEC 15 (72 mm × 72 mm, Hartford Glass Co., Inc.). The glass substrate was cleaned in a sonication bath with soap and deionized water then rinsed in dry ethanol, and washed again with deionized water.…”

plasmonic effect in the cells, and is not just supported or enhanced by it.The operation of plasmonic solar cells is dependent upon the optical excitation of surface plasmons, which are collective oscillations of the surface electronic cloud in metallic nanoparticles. One of the important characteristics of metallic nanoparticles is the coupling interaction of their plasmonic oscillations with incident photons of the same frequency; this coupling excites surface plasmon resonance (SPR). [ 1 ] The SPR gives rise to strong electromagnetic fi elds, which can be used for trapping or refl ecting light, enhancing photovoltaic activity, [ 2 ] surfaceenhanced Raman spectroscopy (SERS), [ 3 ] and photo-catalysis. [ 4 ] When the surface plasmon decays to the ground state it can cause electron excitation within the metallic nanoparticle itself, the excited electrons are often referred to as "hot" electrons. The "hot" electrons are highly active nonequilibrium electrons that have suffi cient kinetic energy to overcome potential barriers, or tunnel through thin layers of semiconductors. [ 5 ] Since the "hot" electrons are energetic they can be used in conjunction with a semiconductor, to form a Schottky barrier photovoltaic device. As the absorption and excitation of the SPR is very wide and extends beyond the visible range of the solar spectrum, depending on the material and structure, the "hot" electrons that are formed can extend the spectral response of the photovoltaic device. The "hot" electrons are directly injected into the conduction band of the semiconductor, forming and improving the photovoltaic activity.One of the semiconductors that is used extensively for renewable energy applications is TiO 2 , which is a wide bandgap (3.2 eV) metal oxide semiconductor. As it is a highly n-type material, it is utilized namely as an electron conducting layer in solar cells to help with charge separation, [ 6 ] or as a photocatalyst for water splitting. [ 7 ] The wide bandgap of the TiO 2 only allows it to be used for solar cells in conjunction with an absorbing material, be it dye, quantum dots, or other materials, since by itself it would only absorb light from the UV part of the solar spectrum. To improve or form the photovoltaic activity of the TiO 2 as an independent photovoltaic system, silver metallic nanoparticles or nanostructures can be used. The metallic nano particles form a Schottky barrier solar cell with the TiO 2 , and the "hot" electrons that have enough kinetic energy to overcome the Schottky barrier height are injected into the TiO 2 , asThe present work reports a simple and direct sputtering deposition to form solid state TiO 2 |Ag independent plasmonic solar cells. The independent plasmonic solar cells are based on a Schottky barrier between two materials, TiO 2 and Ag. The Ag functions as the absorber generating "hot" electrons, as well as the contact for the solar cell. The Ag sputtering is performed for different durations, to form Ag nanoparticles with a wide size distribution on the surface of rough sp...

“…Cu 2 O is mostly p-type semiconductor oxides, having a cubic crystal structure with a space group of Pn3m, its direct band gap of 2.1eV make it possible to possess high optical absorption property in visible spectrum thereby become suitable material for high efficient solar cells. Moreover, Cu 2 O is nontoxic, inexpensive, readily available and have low production costs which satisfy the environmental and economical requirements needed for large-scale applications in solar cell devices, gas and humidity sensors etc (Zulkiflee et al, 2016), (Jayathileke et al,2007), (Pavan et al, 2015)., (Saehana and Muslimin, 2013). Nowadays interest is focused on metal oxides heterojunction solar cell because of their advantage of a low price compared with silicon base solar cell (Pavan et al, 2015).…”
