“…They are an essential component of displays and touchscreens in tablets and mobile phones. They are also key materials in light-emitting diodes as well as in photovoltaics; they form the front electrode in many solar cell technologies: either inorganic thin film solar cells (CIGS, CdTe, amorphous silicon) [2], organic [3] or even the state of the art silicon heterojunction devices [4]. For most of these applications, the specifications of the TCO layers are quite rigid: they must have very high transparency over a broad spectral range, and possess excellent electrical transport properties.…”

Abstract:We report on the electrical and optical properties of ITO and AZO films fabricated directly on silicon substrates under several growth and annealing temperatures. We use broadband spectroscopic ellipsometry measurements (from 300 nm to 20 µm) to obtain a consistent model for the permittivity of each of the films. The results are then used to design an optimized, single layer, high transparency, high conductivity film, suitable as front transparent electrode and low thermal emissivity coating for silicon based solar cells. The best performance is found using the properties of the ITO film grown at 250 ºC, with a state of the art resistivity of 0.2 mΩ-cm and an optimized thickness of 75 nm which leads to 0.79 average absorptivity in the solar range (300-2000 nm) and 0.21 average emissivity in the thermal range (5-20 µm). The structural characterization of the films using X-Ray diffraction, and the Hall mobility and resistivity measurements of all the films are also provided, complementing and supporting the observed optical properties.

“…The world global population is now exciding 7 billion, which implies a greater energy demand [178]. It has been calculated that this demand could by supplied, while the amount of solar energy that impacts the surface of the earth in less than an hour [179]. Solar energy is environment friendly, because it does not pollute like the combusting fossil fuels, this could help decrease the CO2 concentration that in the year 2012 reached 393 ppm, which is past the safe threshold of 350 ppm [180].…”

“…Energy generation through a solar cell depends of several factors, in general terms they are classified by composition and structure, as the following types [179]: First Generation: Single (p-n) junction mono or multi crystalline silicon solar cells, the mono crystalline solar cell has an efficiency record of 25% [184]. Second Generation: Thin films is currently composed of copper indium gallium selenide (CIGS) [179]. This type of cell has achieved efficiency of 20.4% on flexible polymer substrate [184,185].…”

Polymeric Materials for Conversion of Electromagnetic Waves from the Sun to Electric Power

Solar photoelectric energy converted into electricity requires large surface areas with incident light and flexible materials to capture these light emissions. Currently, sunlight rays are converted to electrical energy using silicon polymeric material with efficiency up to 22%. The majority of the energy is lost during conversion due to an energy gap between sunlight photons and polymer energy transformation. This energy conversion also depends on the morphology of present polymeric materials. Therefore, it is very important to construct mechanisms of highest energy occupied molecular orbitals (HOMO)s and the lowest energy unoccupied molecular orbitals (LUMO)s to increase the efficiency of conversion. The organic and inorganic solar cells used as dyes can absorb more photons from sunlight and the energy gap will be less for better conversion of energy to electricity than the conventional solar cells. This paper provides an up-to-date review on the performance, characterization, and reliability of different composite polymeric materials for energy conversion. Specific attention has been given to organic solar cells because of their several advantages over others, such as their low-energy payback time, conversion efficiency and greenhouse emissions. Finally, this paper provides the recent progress on the application of both organic and inorganic solar cells for electric power generations together with several challenges that are currently faced.
