“…In fact, these methods can be used to maximize light absorption and performance optimization. Additionally, Ergen et al [24] utilized screen-engineered field effect Cu 2 O-based solar cells to enable low-cost and high-efficiency cells. In addition, an optimization of InGaP/GaAs single-/multi-junction solar cell performance was presented by Kuan et Yuning in [25] to boost the photovoltaic conversion efficiency, in which when the tunnel junction and back surface field design was optimized, the cell's photovoltaic performance was increased.…”

Here we investigated a novel layer-based optimization technique to improve the performance of a CZTSe solar cell. By using this technique, the optical behavior and electrical properties of the proposed solar cell improved significantly as a result of the changes in the layer specifications and the layer materials. The structure of the cell consisted of an absorber laid on a conducting layer and covered by Indium Tin Oxide (ITO), with ZnO on its top surface. Due to the employment of the CSLO technique, a p+pn junction was formed between the absorber and window layers, which provided a lower recombination rate by transmitting more electrons and holes to the contacts. In addition, the main important parameters affecting the solar cell’s performance such as layer thickness, carrier lifetime, and total effect density were investigated. According to the results, the proposed CZTSe solar cell achieved a 32.6% and 79.5% efficiency and fill factor, respectively—which in comparison to a conventional solar cell is remarkable. Moreover, hybrid structures made by utilizing CZTS-based, Ge-based Cu2ZnGeSe4, and Si-based Cu2ZnSiSe4 with the proposed CZTSe-based solar cell were implemented and better results were achieved, yielding an efficiency of about 42, 50, and 34% and a fill factor of 66, 55, and 42%, respectively, due to the materials’ properties.

Binary copper oxides are a promising class of p-type semiconductors for solar energy conversion applications due to their particular electrical and optical properties, elemental abundance, and non-toxicity. So far, three phases with different copper ion oxidation states, including cuprous Cu2O, paramelaconite Cu4O3, and cupric CuO, have already been successfully synthesized by thin-film deposition techniques. This work reviews recent progress in determining the physical properties of these three phases from the viewpoints of both experimental and theoretical calculations, including their thermodynamics, structure, microstructure, band structure, defects, and their optical and electrical properties. In particular, we discuss some undecided issues regarding the properties of these materials. In addition, we summarize recent advances in photovoltaic cells using copper oxides as absorbers, including correlations between device performance and material properties.
