The SOLWAT system is a combined system for solar water purification and renewable electricity generation. Its photovoltaic and photocatalytic performance, along with the photovoltaic (PV) electricity production was studied under the degradation of three different pollutants: Methylene Blue, Acid...

Direct liquid-immersion cooling of concentrator solar cells was proposed as a solution for receiver thermal management of concentrating photovoltaic (CPV) and hybrid concentrating photovoltaic thermal (CPV-T) systems. De-ionized (DI) water, isopropyl alcohol (IPA), ethyl acetate, and dimethyl...

Better performance can be achieved when the bare silicon solar cells are immersed into liquids for the enhanced heat removing. In this study, the performance of solar cells immersed in liquids was examined under simulated sunlight. To distinguish the effects of the liquid optic and electric...

Direct liquid-immersion cooling of solar cells using dimethyl silicon oil is proposed as a heat dissipation solution for linear CPV (concentrating photovoltaic) systems. To reduce the liquid holdup, a narrow rectangular channel receiver was designed and its heat transfer performance was...

A solar assisted heat pump (SAHP) system was designed by using a roof-integrated solar collector as the evaporator, and then it was demonstrated to provide space heating for a villa in Tianjin, China. A building energy simulation tool was used to predict the space heating load and a three...

The operating mechanism of farmland water conservancy in China was analyzed from the perspective of anthropology, and its dual mechanism characteristics and rules were exposed. The dual mechanism took different focus at different periods, thus there were some defaults. To carry out...

Health inequality is a problem with great political importance all over the world. Urban-rural inequality in health has attracted great attentions in recent years in China, but very few researches have been undertaken into regional discrepancies in health. This research aims at measuring the...

In the paper, a new type of wind-solar hybrid system was proposed, in which multiple small wind turbines took the place of a bigger one. The electricity performance of the multi-turbine wind-solar hybrid system was studied in comparison with the traditional system. Two types of wind-solar hybrid...

Trade theory has no clear prediction on how import protection affects an importing sector's relative size. In this paper, we estimate the impact of US trade protection on industrial production relative size based on a translog GDP functional system. Using an industrial panel data set and...

One of main characteristics for building energy in urban environment is spatially distributed. Both electricity and gas per dwelling in London have positive spatial autocorrelation, which indicates that neighbourhoods tend to cluster together with similar energy use. More importantly, when...
