Photovoltaics systems harness sunlight by using solar cells to convert it directly into electricity. This course covers factors important in the design of solar cells which are studied with regard to their effects on spectral response, temperature sensitivity, resistive losses, current generation and open circuit voltages. A range of solar cell technologies are considered both at the laboratory and commercial levels, including advanced concepts and designs for photovoltaic modules. Significant emphasis is placed on applications including systems design, construction and operation with this subject building on the material introduced in the subject Applied Photovoltaics. Relevant types of systems receive particular attention. Experience will be gained with the computer-aided design procedures for photovoltaic systems. Management and entrepreneurial approaches in relation to starting a small business within the photovoltaic industry are also considered.
