“…An analysis of the absorption coefficient (Fig. 2a) shows that the rise of a in the photon energy range hv Q 1.40eV follows the relation, sll = (A,/hv)(hv -Egl)"', (1) with Egl = 1.29eV which corresponds to an allowed direct transition between parabolic bands. However, if we calculate a1 using A , and Eg, , for energies above 1.40 eV, we find that a1 becomes considerably smaller than the absorption coefficient (a) measured experimentally, indicating the existence of additional absorption processes.…”

“…A theoretical value of 0.21 at absolute zero has also been calculated [116]. A preponderance of the room temperature data is in the range of 0.14 [120] to 0.16 [121] so the intermediate value of b = 0.151 from the original work by Bodnar and coworkers is accepted here [122], leading to the following expression for α-CuIn1-XGaXSe2:…”

This project was initiated after the Boeing Company decided to terminate its photovoltaic research and development efforts, and donated some research equipment to UF. Billy Stanbery, who was part of the Boeing team, decided then to enroll at UF to pursue a Ph.D degree. As such these events constituted a rare direct technology transfer from industry to a university. This helped to preserve more than the published legacy of the solar cell efforts at Boeing, and jump-started a comprehensive, multifaceted, and multidisciplinary copper indium diselenide solar cell research effort at UF. 5-15 Micro-Raman scattering spectra of islands on two indium-rich CIS films grown on GaAs (100). The uppermost curve is from an island "pool" on a sodium-dosed film and the lower two are single and averaged spectra from isolated islands on the sample without sodium shown in Figure 5- field. It focused primarily on the physical and opto-electronic properties of the general class of I-III-VI2 and II-IV-V2 compound semiconductors. More recent reviews specifically oriented towards CIS materials and electronic properties [2][3][4][5][6] are also recommended reading for those seeking to familiarize themselves with key research results in this field.There are also a number of excellent books and reviews on photovoltaic device physics [7,8], on the general subject of solar cells and their applications [9,10], and others specifically oriented towards thin-film solar cells [11,12] Researchers have not always been careful to reserve the use of the compound designation CuInSe2 for single-phase material of the designated stoichiometry, an imprecision that is understandable in view of the difficulty in discriminating CuInSe2 from some other compounds in this material system, as will be discussed in detail elsewhere in this treatise. The compound designations such as CuInSe2 will be reserved herein for reference to single-phase material of finite solid solution extent, and multiphasic or materials of indeterminate structure composed of copper, indium, and selenium will be referred to by the customary acronym, in this case CIS. 3 This review begins with an overview of the physical properties of the principal copper ternary chalcogenides utilized for PV devices, including their thermochemistry, crystallography, and opto-electronic properties. All state-ofthe-art devices rely on alloys of these ternary compounds and employ alkali impurities, so the physical properties and effects of these additives will be presented, with an emphasis on their relevance to electronic carrier transport properties. This foundation will provide a basis from which to address the additional complexities and variability resulting from the plethora of materials processing methods and device structures which have been successfully employed to fabricate high efficiency PV devices utilizing absorbers belonging to this class of materials.

Thin-film solar cells are preferable for their cost-effective nature, least use of material, and an optimistic trend in the rise of efficiency. This paper presents a holistic review regarding 3 major types of thin-film solar cells including cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and amorphous silicon (α-Si) from their inception to the best laboratory-developed module. The remarkable evolution, cell configuration, limitations, cell performance, and global market share of each technology are discussed. The reliability, availability of cell materials, and comparison of different properties are equally explored for the corresponding technologies. The emerging solar cell technologies holding some key factors and solutions for future development are also mentioned. The summarized part of this comparative study is targeted to help the readers to decipher possible research scopes considering proper applications and productions of solar cells.
