Experimental and economical performance investigation of V-trough concentrator with different reflectance characteristic in photovoltaic applications

open access: yesJournal of Cleaner Production, 2020
Abstract Lack of consideration of photovoltaic panel temperature in a concentrating photovoltaic (CPV) system causes a great misconception and leads to the financial risk of system installation since the increment in PV cell temperature significantly reduces the performance.

When Do Robots Go Green? Unveiling Mechanisms, Thresholds, and Spillovers of Industrial Robotics on Global Ecological Capacity

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper examines the relationship between industrial robotics adoption and ecological capacity, measured by biocapacity, using panel data from 50 countries over the period 2000–2024. We investigate the transmission mechanisms, non‐linearities, spatial spillovers, and heterogeneity characterizing this relationship.

Techno-economical evaluation of parabolic trough collectors systems for steam processes in the Chilean industry [PDF]

open access: yesAIP Conference Proceedings, 2018
The Chilean industry sector presents an extensive energy consumption which is mainly supplied by fossil fuels. The solar resource available in the country offers an opportunity to supply heat to low and medium temperature processes. The present study evaluates the techno-economical potential of generating solar process heat through a parabolic trough ...
