Photovoltaic cell efficiency at elevated temperatures
In order to determine what type of photovoltaic solar cell could best be used in a thermoelectric photovoltaic hybrid power generator, we tested the change in efficiency due to higher temperatures of three types of solar cells: a polymer cell, an amorphous silicon cell and a CIS cell. Using an …

The performance of an integral greenhouse solar air-heater
The Baird-type solar collector is a solar air-heater, utilising black shade-cloth as the absorber, that is incorporated as part of the roof of a greenhouse. It is intended to be used, in conjunction with a heat storage device, to provide greenhouse heating (and cooling), and so to assist in …
