Closing the loop for perovskite solar modules

  • Posted by R2ES Laboratory
  • On 25 Giugno 2021
Perovskite solar cell modules are expected to enter the market in the near future, but their implications in terms of sustainability compared to other photovoltaic devices are still debated. Now a study lays the groundwork for their eco-design. ince the first demonstration in 2009, perovskite solar cells (PSCs) have emerged as a disruptive class of […]

Synthesis and Characterization of New Organic Dyes Containing the Indigo Core

  • Posted by R2ES Laboratory
  • On 27 Luglio 2020
A new series of symmetrical organic dyes containing an indigo central core decorated with different electron donor groups have been prepared, starting from Tyrian Purple and using the Pd-catalyzed Stille-Migita coupling process. The effect of substituents on the spectroscopic properties of the dyes has been investigated theoretically and experimentally. In general, all dyes presented intense […]

Environmental and economic optima of solar home systems design: A combined LCA and LCC approach

  • Posted by R2ES Laboratory
  • On 11 Luglio 2020
This paper compares the economic and environmental optimal design of Solar Home Systems (SHSs) and explores the role of economic incentives (such as tariffs and technology costs) in approximating the two optima. To achieve that, we present a methodology for the environmental and economic evaluation of grid-connected SHSs: user-scale electric systems involving a photovoltaic (PV) […]

Exergo‐Economic and Environmental Analysis of a Solar Integrated Thermo‐Electric Storage

  • Posted by R2ES Laboratory
  • On 6 Luglio 2020
Renewable energies are often subject to stochastic resources and daily cycles. Energy storage systems are consequently applied to provide a solution for the mismatch between power production possibility and its utilization period. In this study, a solar integrated thermo‐electric energy storage (S‐TEES) is analyzed both from an economic and environmental point of view. The analyzed […]

Life Cycle Assessment of Classic and Innovative Batteries for Solar Home Systems in Europe

  • Posted by R2ES Laboratory
  • On 4 Luglio 2020
This paper presents an environmental sustainability assessment of residential user‐scale energy systems, named solar home systems, encompassing their construction, operation, and end of life. The methodology adopted is composed of three steps, namely a design phase, a simulation of the solar home systems’ performance and a life cycle assessment. The analysis aims to point out […]

Integrating urban metabolism and life cycle assessment to analyse urban sustainability

  • Posted by R2ES Laboratory
  • On 15 Gennaio 2020
In recent decades, the close correlation between urban development and the concept of sustainability has become increasingly evident and important. This is demonstrated by European Union policies concerning EU cities and the United Nations 2030 Agenda for Sustainable Development, including sustainable development goal (SDG) 11: Sustainable cities and communities. In the context of increasing urbanization, it […]

Prospective life cycle assessment of third-generation photovoltaics at the pre-industrial scale: A long-term scenario approach

  • Posted by R2ES Laboratory
  • On 13 Gennaio 2020
The development of sustainable technologies for energy generation should necessarily undergo sustainability assessment. A well-recognized, valuable tool to accomplish this task is the life cycle assessment. In particular, prospective life cycle assessment can provide the useful methodological framework to calculate eco-profiles of third-generation photovoltaic technologies with a future-oriented perspective. In this paper, we present the […]

Environmental analysis of a nano-grid: A Life Cycle Assessment

  • Posted by R2ES Laboratory
  • On 14 Novembre 2019
Renewable energy sources are fundamental to face the problem of climate changes. Unfortunately, some resources, such as wind and solar radiation, have fluctuations affecting the electrical grids stability. Energy storage systems can be used for a smart energy management to accumulate power from renewable sources. For such reason, these devices play a key role to […]
