Fabrication of Perovskite Solar Cells by the Smart Stacking Process

Received: 21 September 2022;  Published: 25 November 2022;  doi: 10.21926/jept.2204038

Abstract

The most commonly used process for fabricating perovskite solar cells is based on wet chemistry, which greatly limits the choice of materials suitable for optimizing the performance of the device. We developed a new approach for the fabrication of perovskite-based solar cells. In the smart stacking process, the perovskite solar cell was assembled by stacking two pieces of perovskite films prepared separately. A working perovskite solar cell was developed with PCE = 0.78% and the perovskite layer [...]

The Impacts of Offshore Wind Farms (OWFs) on Local Tourism and Recreation -- Evolving Lessons from Practice

Received: 06 July 2022;  Published: 16 November 2022;  doi: 10.21926/jept.2204037

Abstract

The article examines the nature of impacts of the rapidly growing Offshore Wind Farm (OWF) industry on tourism and recreation in coastal communities, especially in the UK. The multi-methods research approach includes reviews of literature, content of OWF Environmental Statements (ESs) for predicted impacts, recent practice for actual impacts, and the use of mitigation and enhancement measures. Findings from literature indicate that the overall impact on tourism appears relatively benign, and som [...]

A Data-Based Reliability Analysis of ESP Failures in Oil Production Wells

Received: 27 September 2022;  Published: 14 November 2022;  doi: 10.21926/jept.2204036

Abstract

Electrical Submersible Pumps (ESPs) are one of the most widely used artificial lift methods in the petroleum industry. However, ESP failures are unanticipated and common occurrences with significant financial impacts for the operators. Analysis of the ESP performance and failures are essential in its design and optimization. This paper presents a statistical approach for diagnosing and evaluating the root causes of ESP failures. The analysis is based on the field data gathered from the surface a [...]

Comparing Environmental Impacts Arising from the Use of Electric Two-Wheeler vis-a-vis Gasoline Two-Wheeler in India

Received: 26 July 2022;  Published: 09 November 2022;  doi: 10.21926/jept.2204035

Abstract

Electric vehicles are becoming popular among consumers while BS-VI norms have been introduced and mandated for conventional vehicles in India. In the present study, the environmental impacts from the use phase of electric two-wheeler (EV) and gasoline two-wheeler (GV) have been evaluated and compared using the life cycle assessment (LCA) perspective. The functional unit adopted was 1000 km driven by one vehicle under Indian road and traffic conditions. CML 2001 and ReCiPe 2016 method [...]

A Dual-PRF Scan Mode and Adaptive Doppler-Velocity Dealiasing to Increase Radar Clear-Air Velocity Data Coverage and Usability

Received: 05 August 2022;  Published: 13 October 2022;  doi: 10.21926/jept.2204034

Abstract

By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the [...]

TEA of a Unique Two-Pathways Process for Post-Combustion CO2 Capture

Received: 01 August 2022;  Published: 13 October 2022;  doi: 10.21926/jept.2204033

Abstract

A unique two-Pathways process using aqueous sodium glycinate for CO2 capture from a split flue gas stream emitted from 600 MWe post-combustion coal power plant was developed in Aspen Plus v.10. The split gas flow rate used was 44.75 ton/h and contained 0.0023 mol% SO2 and 13.33 mol% CO2. The process includes a washing unit, a CO2 absorption unit, a reverse osmosis unit, and a solvent regeneration unit or [...]

The Physical Potential for Dutch Offshore Wind Energy

Received: 04 August 2022;  Published: 10 October 2022;  doi: 10.21926/jept.2204032

Abstract

In the Netherlands, an important way to contribute toward achieving climate goals is the large-scale deployment of wind turbines in the North Sea. The North Sea is a unique location for offshore wind power thanks to its strong winds, shallow waters, and proximity to large energy users. Wind turbines generate electricity by extracting kinetic energy from the atmosphere. This kinetic energy is replenished at a finite rate through the mixing of atmospheric layer [...]

A Robust Second-Order Conic Programming Model with Effective Budget of Uncertainty in the Optimal Power Flow Problem

Received: 29 December 2021;  Published: 09 October 2022;  doi: 10.21926/jept.2204031

Abstract

Integrating large-scale wind energy in modern power systems necessitates high-efficiency mathematical models to address classical assumptions in power systems. In particular, two main assumptions for wind energy integration in power systems have not been adequately studied. First, nonlinear AC power flow equations have been linearized in most of the literature. Such simplifications can lead to inaccurate power flow calculations and result in technical issues. Second, wind power uncertainties are [...]
