The role of climatic-design-operational parameters on combined PV/T collector performance: a critical review

PV/T technology attracted numerous researchers and professionals during the last decades. There are many review papers in the literature evaluated the R&D aspects of PV/T collectors. In fact, there are abundant of case studies discussed the parameters of climate, design and operational conditions affected the PV/T collector performance. But, a comprehensive compilation of the information of those case studies is still a missing link in the literature. Hence, this paper intended to review thoroughly the information regarding the parameters affecting the PV/T collector performance mainly and PV module performance partially. The parameters are supported with the most available R&D to measure the accurate influence of each parameter on the performance. The outcomes from the study are highlighted in lessons learned section

Voluntary disclosure research: which theory is relevant?

The purpose of this paper is to overview the most popular theories that have been used in prior research to explain voluntary corporate disclosures and to provide guidance about the choice of a suitable theory or theories for different types of voluntary disclosure research. It presents a comprehensive comparison of voluntary disclosure theories and relates each of the theories to the type of information disclosure being examined. Following prior research, we classify disclosures into strategic and forward looking, financial, and non-financial information. We show that similarities and differences between theories stem from underlying paradigm differences which are related to incentives to disclose and the costs and benefits considered by each theory. The choice of a suitable theory to underpin the research depends on the type of information disclosure being examined and the external parties considered
