Preparation and characterization of organic solar cell.Bell, July Teboho. 12 February 2014 (has links)
Organic molecules based photovoltaic cells were fabricated in an open laboratory conditions without the use of glove box or clean room. Conducting
polymers such as P3HT and PCBM were used as a photo-active layer of the
devices. We found significant difference in the performance of the devices
by employing two laboratory conditions of the polymer solutions. Enhanced
current density has been observed from P3HT/PCBM bulkheterojunction
solar cell after diluting a well sonicated polymers solution with fresh chloroform solvent. As the result of such current surge in the devices the efficiency
rose to more than double compared to those devices without dilution of the
P3HT/PCBM solution. An average power conversion efficiency of 4.5% was
then recorded from the new preparation condition. This is an encouraging
development toward achieving low cost organic photovoltaic devices. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Design and performance analysis of hybrid photovoltaic-thermal grid connected system for residential application.Mutombo, Ntumba Marc-Alain. January 2012 (has links)
High output electrical energy is obtained from photovoltaic (PV) systems subject to high
irradiance. However, at high irradiance, the efficiency of PV systems drops due to increase of
the temperature of the systems. In order to improve the efficiency of photovoltaic systems, much
effort has been spent on developing hybrid photovoltaic thermal (PVT) systems using water as a
coolant to withdraw heat from solar modules.
This research is focused on the study of the behavior of hybrid PVT collectors using rectangular
channel profiles which provide a large surface for heat exchange between PV panels and thermal
collectors unlike the circular channel profile used in conventional PV systems. In hybrid PVT
systems, coolant water circulates in a closed circuit by means of the thermosyphon phenomenon
and the heat from this water is extracted from a storage tank and can be used in hot water
systems instead of an electric geyser.
Numerical models of water velocity in channels due to the thermosyphon phenomenon and the
temperature of solar modules was developed and a system was designed for modest Durban
household demand. A simulation was run for specific summer and winter days comparing a
conventional PV system and a hybrid PVT system. The results were very encouraging, and
demonstrated that the equipment is capable of extending the PVT application potential in the
domestic sector where more than 40% of electricity cost is heating water. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, Durban, 2012.
