A Status Review on Cu2ZnSn(S, Se)4-Based Thin-Film Solar Cells Int. J. Photoenergy (IF 1.88) Pub Date : 2020-09-01 Sudipto Saha
Photovoltaics has become a significant branch of next-generation sustainable energy production. Kesterite Cu2ZnSn(S, Se)4 (copper-zinc-tin-(sulfur, selenium) or CZTS(Se)) is considered one of the most promising, earth-abundant, and nontoxic candidates for solar energy generation over the last decade. However, shallow phase stability of the quaternary phase and the presence of various secondary phases

Performance Analysis of Ti-Doped In2O3 Thin Films Prepared by Various Doping Concentrations Using RF Magnetron Sputtering for Light-Emitting Device Int. J. Photoenergy (IF 1.88) Pub Date : 2020-08-28 Wittawat Poonthong; Narong Mungkung; Pakpoom Chansri; Somchai Arunrungrusmi; Toshifumi Yuji
The influences of doping amounts of TiO2 on the structure and electrical properties of In2O3 films were experimentally studied. In this study, titanium-doped indium oxide (ITiO) conductions were deposited on glass substrate by the dual-target-type radio frequency magnetron sputtering (RFS) system under different conditions of Ti-doped In2O3 targets, from Ti-0.5 wt% to Ti-5.0 wt%, along with 10 mTorr

Analyzing the Off-Grid Performance of the Hybrid Photovoltaic/Diesel Energy System for a Peripheral Village Int. J. Photoenergy (IF 1.88) Pub Date : 2020-08-17 Ahmed I. M. Iskanderani; Ibrahim M. Mehedi; Makbul A. M. Ramli; Md. Rafiqul Islam
Grid extension from the distribution network is being used to meet the demand for rural electricity all over the world. Due to the extra cost of extending electric lines to rural villages, it is not feasible as the installing and commissioning costs are directly related to several constraints such as distance from the main grid, the land location, utilities to be used, and the size of the approximate

A Modified ESC Algorithm for MPPT Applied to a Photovoltaic System under Varying Environmental Conditions Int. J. Photoenergy (IF 1.88) Pub Date : 2020-08-13 Arnaud Flanclair Tchouani Njomo; Godpromesse Kenne; Rostand Marc Douanla; Lionel Leroy Sonfack
Photovoltaic solar energy is one of the most important renewable energy sources. However, the production of this energy is nonlinear and varies depending on atmospheric parameters. Therefore, the operating point of the photovoltaic panel (PV) does not always coincide with the maximum power point (MPP). A mechanism that allows the research of the maximum power point known as maximum power point tracking

Study on the Improved Electrical and Thermal Performance of the PV/T Façade System Int. J. Photoenergy (IF 1.88) Pub Date : 2020-08-12 Ruobing Liang; Yan Gao; Peng Wang; Chao Zhou
This paper is aimed at improving the performance of a building-integrated photovoltaic thermal (BIPV/T) system driven by a refrigerant pump. The research is aimed at optimizing and upgrading the BIPV/T system to address the shortcomings of the original system by replacing roll-bond PV/T units with improved heat transfer features. The system’s connecting form was redesigned using a liquid separator
