Achieving high temperature thermal outputs from concentrating photovoltaic/thermal (PV/T) systems presents a challenge in that the performance of the PV cells declines with increasing temperature. Spectral beam splitting is an attractive approach to address this conflict by thermally decoupling...

In this paper we propose a new solar thermal collector which is suitable for providing heat for endothermic chemical reactions. The particular reaction that is considered is hydrogen production by menthol reforming. The design presented here is based on CPC (compound parabolic concentrator)...

The efficient utilization of the solar spectrum has been intensively addressed by solar researchers in the last decades. For instance, many efforts have been made to improve the efficiency of PV cells and to allow their operation at high temperatures and concentration ratios (CR). On the other...

Hybrid photovoltaic/thermal (PV/T) devices can simultaneously generate thermal and electrical energy, but have been limited to low temperature applications. This is done to avoid performance degradation of the PV cell at high temperatures. While the low temperature approach limits PV losses, it...

In late 2001, soon after numerous financial reporting failures including the much publicized demise of Enron, the SEC began a series of initiatives to improve critical accounting policy (CAP) and critical accounting estimate disclosures included within the MD&A section of Form 10-K. The first...
