“…4, in which it can be seen that the As-deposited device without a Zn 2 SnO 4 buffer layer and CdCl 2 treatment show very poor parameters including open circuit voltage Voc, short circuit current density Jsc, Fill Factor FF and overall performance for both CdS thicknesses of 120nm and 80nm. This is well known to be attributed to the low temperature used to fabricate these layers at 200 C 0 that introduce poor structure properties and low CdTe layer doping as it has been already investigated previously (Kadhim, Harrison et al 2016. After exposing the device to the CdCl 2 treatment at 450C 0 as described in the experimental part above, the solar cells that has 120nm CdS thickness show improved Voc, Jsc, FF and efficiency ɳ (5.1%), (See Fig.4).…”

In this paper, a highly transparent and conductive Zinc Stannate (Zn 2 SnO 4) buffer layer is integrated between the transparent conductive oxide (TCO) layer and the Cadmium Sulfide (CdS) window layer to improve the optical properties of (TCO\Zn2SnO4\CdS\CdTe) heterojunctions in CdTe\CdS solar cells. This buffer layer is used to reduce the excess interdiffusion between the window and absorber layers when Ultra-thin CdS window layer, d < 100 nm, is employed, and post CdCl 2 treatment is applied at high temperature after deposition of CdTe layer. The fabricated Zinc Stannate (Zn 2 SnO 4) buffer layer was found to have ideal transmission, reflectance and absorption properties which helped in introducing good optical properties in the short wavelengths. It has been found that using the Zn 2 SnO 4 buffer layer enhanced the short circuit current Jsc and the open circuit voltage Voc of the solar cells that used Ultra-thin CdS thickness (80nm) by preventing TCO\CdTe direct contact, and led to improved solar cells' performance and reproducibility.

“…Its development dates back to the mid-1990s 264 , with commercialization by companies such as Symyx Technologies, PVD Products, Neocera and Intermolecular spanning a wide application space. The systems developed by these companies can deposit whole libraries of compositions, starting from elemental or even compound sources [265][266][267][268][269][270][271][272] . This enables searches for individual phases, disordered structures, solid solutions, multilayered heterostructures, super-lattices and other discoveries.…”

| The discovery and development of novel materials in the field of energy are essential to accelerate the transition to a low-carbon economy. Bringing recent technological innovations in automation, robotics and computer science together with current approaches in chemistry , materials synthesis and characterization will act as a catalyst for revolutionizing traditional research and development in both industry and academia. This Perspective provides a vision for an integrated artificial intelligence approach towards autonomous materials discovery , which, in our opinion, will emerge within the next 5 to 10 years. The approach we discuss requires the integration of the following tools, which have already seen substantial development to date: high-throughput virtual screening, automated synthesis planning, automated laboratories and machine learning algorithms. In addition to reducing the time to deployment of new materials by an order of magnitude, this integrated approach is expected to lower the cost associated with the initial discovery. Thus, the price of the final products (for example, solar panels, batteries and electric vehicles) will also decrease. This in turn will enable industries and governments to meet more ambitious targets in terms of reducing greenhouse gas emissions at a faster pace. volume 3 | mAY 2018 | 5 PERSPECTIVES

“…However, despite these advantages, the higher degree of control of the compositional gradient that can be achieved with PVD techniques makes them the preferred strategy for synthesizing thin-film combinatorial samples. [64] Focusing on chalcogenidebased solar cells, synthesized by combinatorial methods, there exist several works reporting the employment of sputtering, [69][70][71][72][73][74][75][76][77][78][79] a lower amount of articles report the use of thermal evaporation [80][81][82][83] and CBD, [66,84,85] and there are also reports describing the use of spray coating, [68,86] PLD, [87] and CVD. [88] The experimental setups required for adapting both PVD and CM techniques for the deposition of combinatorial samples are discussed in a review by McGinn.…”

Combinatorial Analysis Methodologies for Accelerated Research: The Case of Chalcogenide Thin‐Film Photovoltaic Technologies

et al. 2022

One of the fastest ways for the discovery, understanding, development, and further optimization of new complex materials is the application of combinatorial analysis methodologies, which have already shown impressive results for different organic and inorganic materials, leading to the fast development of different scientific fields and industrial applications. However, in the case of thinfilm materials for optoelectronic devices and, in particular, for second-generation photovoltaic (PV) devices, the application of combinatorial analysis is still quite uncommon with a desultory rather than systematic application. The present review discusses the main constraints for the application of combinatorial analysis to thin-film materials with a focus on chalcogenide compounds and different strategies to overcome them. Special attention is paid to the requirements for the preparation of graded thin films, characterization, and analysis of the results, providing different hints for the implementation of high-quality combinatorial analysis. Finally, an overview of the currently published results in the field of chalcogenide thin-film PV technologies is presented, showing the relevance of the combinatorial approach for boosting the development not only of this promising PV technology, but also of other optoelectronic devices based on complex materials and multilayered structures.
