Application of LCA to Determine Environmental Impact of Concentrated Photovoltaic Solar Panels—State-of-the-Art

Photovoltaic systems represent a leading part of the market in the renewable energies sector. Contemporary technology offers possibilities to improve systems converting sun energy, especially for the efficiency of modules. The paper focuses on current concentrated photovoltaic (CPV) technologies, presenting data for solar cells and modules working under lab conditions as well as in a real environment. In this paper, we consider up-to-date solutions for two types of concentrating photovoltaic systems: high-concentration photovoltaics (HCPV) and low-concentration photovoltaics (LCPV). The current status of CPV solar modules was complemented by the preliminary results of new hybrid photovoltaic technology achieving records in efficiency. Compared to traditional Si-PV panels, CPV modules achieve greater conversion efficiency as a result of the concentrator optics applied. Specific CPV technologies were described in terms of efficiency, new approaches of a multijunction solar cell, a tracking system, and durability. The results of the analysis prove intensive development in the field of CPV modules and the potential of achieving record system efficiency. The paper also presents methods for the determination of the environmental impact of CPV during the entire life cycle by life cycle assessment (LCA) analysis and possible waste management scenarios. Environmental performance is generally assessed based on standard indicators, such as energy payback time, CO2 footprint, or GHG emission

Application of deferred annuities in an occupational pension scheme

Aim of this paper is to construct a model that would allow to calculate expected benefit amount in a scheme financed by SPDA, and to compare it with an amount that could be achieved in a traditional DC scheme. Second aim is to extend the concept of SPDA scheme to allow for the risk of high annuity prices to be shared between member and employer [...]

Pensions today - economic, managerial, and social issues

The book is double-blind peer reviewed.Lodz University of Technology Press does not take responsibility for the content and editing of this publication.Cover design: Gajderowicz, AleksandraWydawnictwo PŁ nie ponosi odpowiedzialności za treść i opracowanie redakcyjne niniejszej publikacji.The monograph includes 23 chapters addressing the problems of contemporary pensions from both a general and a national view, studied from a theoretical or empirical perspective. The book is structured as follows. First, the managerial, administrative and business aspects of retirement and pension wealth are discussed. The next five sections are devoted to very important and current problems of family and gender issues in the context of old-age social security. The subsequent six chapters refer to other social and economic aspects of pensions with some references to social security reforms. In the next three sections, some financial and actuarial issues are discussed and investigated. Finally, in the last five chapters, the authors address selected problems of pension reform with special attention paid to their policy and legal aspects. In these 23 chapters, issues concerning various countries are presented. In some chapters, a single-country empirical approach is employed (with reference to Poland, Spain, Turkey, Slovakia, Latvia, or Czechia, for example), whereas some other sections present multinational studies

Impact of a pension system and an enterprise on employees’ retirement: an intergenerational context

Thus, the goal of this paper is to identify and characterize main elements of this nexus in the context of retirement decisions taking intergenerational relations into account. We focus on the pension system’s impact (with its main parameter, which is a pensionable age (statutory retirement age)) on the employers’ behaviour, as well as the employers’ (workplace) impact on employees’ retirement decisions (reflected in effective retirement age). The paper is structured as follows. First, we present a pension system in an intergenerational context. Second, we attempt to discuss a pensionable age as a determinant of an enterprise activity in the role of an employer. The subsequent section tackles the issue of the possible impact of the employer on employees’ retirement decisions. The paper ends with a brief summary of issues discussed

The effects of applying behavioral impulses (“nudges”) to stimulate the development of occupational pension schemes – comparative analysis

This paper studies the effect of introducing automatic enrollment into workplace pensions in the following chosen countries: New Zealand, Great Britain, Turkey). The main aim of the research, preliminary results of which have been presented in this paper, was to seek an answer to a fundamental question: whether behavioral stimuli (nudges) proved to be effective in different countries and in different pension schemes, or whether there were significant differences in the strength of their impact. And if such differences were identified – what factors would influence the effectiveness of nudges in pension systems of different countries [...]
