“…Thin CdTe films can be synthesized by various techniques such as close-space sublimation [11], metal-organic chemical vapour deposition [12], molecular beam epitaxy [13], thermal-vacuum evaporation [14], electro-chemical deposition [15], etc. Among these methods, electrodeposition is a simple and attractive method with the benefits of low-cost technology, environment-friendly nature, isothermal process, mainly controlled by electrical parameters such as precursors of electrolyte solution, deposition potential, which decides the film quality, composition and morphologies of the films.…”

Semiconducting nanomaterials of II-VI groups are the key elements of continued technological approaches made in the field of optoelectronic, magnetic and photonic devices due to their size-dependent properties. Ion beams create changes in the material along their track; this not only exhibits excellent properties but also tailors new materials. This article reports the effect of Ar + ion implantation on the properties of cadmium telluride thin films of about 80 nm thickness. The implantation parameters were adjusted based on computer-aided learning using SRIM (stopping and range of ions in matter) software. The CdTe thin films were deposited by electrodeposition method on ITO substrate. Thin films of CdTe are exposed to Ar + ions with different fluencies of 1 × 10 15 , 5 × 10 15 and 1 × 10 16 ions cm −2 at Ion Beam Centre, Kurukshetra University, Kurukshetra, India. After implantation, the films were characterized using UV-visible spectroscopy, photoluminescence (PL) and a four-probe setup with a programmable current-voltage (I-V) source metre. The scanning electron microscopy of pristine film showed smooth and uniform growth of sphere-shaped grains on substrate surface. From optical studies, the values of optical band gap for as-deposited and argon-ion-implanted thin films were calculated. It was found that values of optical band gap decreased with the increase in fluence of ion beam. From PL studies it was found that the intensity got increased with ion fluence. A considerable increase in current was noticed from I-V measurements with ion fluence after implantation. Different properties of pre-and post-implanted thin films are studied.

“…This figure shows that the response observed below 500 nm is due to the small thickness of CdS (70 nm). This thin layer allows a fraction of photons with energy above its band-gap (2.42 eV) to be transmitted to the CdTe absorber layer, contributing to an increased photocurrent [27]. With further increase in wavelength an increase in η ext is observed.…”

“…It was found that the silver paste did not form a suitable ohmic contact when printed directly onto the CdTe surface. A carbon/silver stack was necessary to successfully form an ohmic contact as reported in the literature [8,9] to form large area CdTe modules. Comparable efficiencies using the screen printed pastes compared to the standard gold contacts were obtained when using laboratory scale contacts of 0.25 cm 2 as seen in Table I.…”

Thin film deposition process and integrated scribing technologies are key to forming large area Cadmium Telluride (CdTe) modules. In this paper, baseline Cd 1-x Zn x S/CdTe solar cells were deposited by atmospheric-pressure metal organic chemical vapor deposition (AP-MOCVD) onto commercially available ITO coated boro-aluminosilicate glass substrates. Thermally evaporated gold contacts were compared with a screen printed stack of carbon/silver back contacts in order to move towards large area modules. P2 laser scribing parameters have been reported along with a comparison of mechanical and laser scribing process for the scribe lines, using a UV Nd:YAG laser at 355 nm and 532 nm fiber laser.
