Assessment of Cu(In, Ga)Se2 Solar Cells Degradation due to Water Ingress Effect on The CdS Buffer Layer

Received: 28 October 2020;  Published: 06 January 2021;  doi: 10.21926/jept.2101001

Abstract

The effect of water ingress on the surface of the buffer layer of a Cu(In, Ga)Se2 (CIGS) solar cell was studied. Such degradation can occur either during the fabrication process, if it involves a chemical bath as is often the case for CdS, or while the modules are in the field [...]

Solar Thermal Energy Stills for Desalination: A Review of Designs, Operational Parameters and Material Advances

Received: 28 September 2020;  Published: 29 December 2020;  doi: 10.21926/jept.2004018

Abstract

The demand for high-quality freshwater is increasing due to global population growth, intensifying agricultural practices and expanding industrial development. Additionally, many global regions have low levels of rainfall which makes them arid and incapable of supporting large human populations or a [...]

Further Understanding of Uncertainties in the Impedance Spectrum of the Polymer Electrolyte Fuel Cell due to Inductive Effects and Oxygen Diffusion Time Constant

Received: 31 July 2020;  Published: 24 November 2020;  doi: 10.21926/jept.2004017

Abstract

In this study, uncertainties during the assessment of the electrochemical impedance spectrum of the polymer electrolyte fuel cell (PEFC) attributed to inductive artefacts at high frequencies and inductive loops at low frequencies as well as oxygen diffusion time constant are discussed. A validated i [...]

Research Requirements to Move the Bar forward Using Aqueous Formate Salts as H2 Carriers for Energy Storage Applications

Received: 01 September 2020;  Published: 23 November 2020;  doi: 10.21926/jept.2004016

Abstract

In this perspective on hydrogen carriers, we focus on the needs for the development of robust active catalysts for the release of H2 from aqueous formate solutions, which are non-flammable, non-toxic, thermally stable, and readily available at large scales at reasonable cost. Formate salts can be st [...]

Testing the Correlation between Prior Knowledge of - and Visualisation Guided WTPs for Reducing the Visual Impacts Visual from Offshore Wind Farms

Received: 28 April 2020;  Published: 12 August 2020;  doi: 10.21926/jept.2003015

Abstract

Visual external costs are significant elements in the cost-benefit analysis of wind farm locations. This has been demonstrated well in the literature. However, in the assessment of the visual costs, a large share of the earlier studies used no or only simplistic visualizations of the visual impacts [...]
