Low Temperature Solar Collectors

Demonstration of Solar Heating and Cooling System using Sorption Integrated Solar Thermal Collectors

Producing cost-competitive small and medium-sized solar cooling systems is currently a significant challenge. Due to system complexity, extensive engineering, design and equipment costs; the installation costs of solar thermal cooling systems are prohibitively high. In efforts to overcome these limitations, a novel sorption heat pump module has been developed and directly integrated into a sola...

Roof Integrated Solar Absorbers: The Measured Performance of “Invisible” Solar Collectors: Preprint

The Florida Solar Energy Center (FSEC), with the support of the National Renewable Energy Laboratory (NREL), has investigated the thermal performance of solar absorbers which are an integral yet indistinguishable part of a building’s roof. The first roof-integrated solar absorber (RISA) system was retrofitted into FSEC’S Flexible Roof Facility in Cocoa, Florida in September 1998. This “proof-of...

Transparent carbon nanotube sheets as 3-D charge collectors in organic solar cells

Strong transparent multiwall carbon nanotube (t-CNT) sheets [M. Zhang, S. Fang, A.A. Zakhidov, S.B. Lee, A.E. Aliev, C.D. Williams, K.R. Atkinson, R.H. Baughman, Science 309 (2005) 1215] can be used as effective anodes in organic photovoltaic cells (OPV) [A.D. Pasquier, H.E. Unalan, A. Kanwal, S. Miller, M. Chhiwalla, Appl. Phys. Lett. 87 (2005) 203511]. We prove here that t-CNT plays an essent...

Exergy Analysis of Flat Plate Solar Collectors

This study proposes the concept of the local heat loss coefficient and examines the calculation method for the average heat loss coefficient and the average absorber plate temperature. It also presents an exergy analysis model of flat plate collectors, considering non-uniformity in temperature distribution along the absorber plate. The computation results agree well with experimental data. The ...
