Abstract
Concentrated photovoltaic system (CPV) uses different, uniquely designed components to capture the sunlight, also known as solar energy, and transfer that energy to a small photovoltaic cell. These small cells have high efficiency. Multi-junction solar cells are used in CPV as they provide higher conversion efficiencies, on the same time reducing the quantity of costly, environmentally sensitive semiconductor materials. Mostly, the previous designs have issues of low efficiency in terms of irradiance uniformity. To this end, a design methodology to increase irradiance uniformity over solar cell is presented. In the design, maximum sunlight will be focused over cell by minimizing losses. This CPV system comprises a parabolic trough which will work as a primary reflector, reflecting all the incident light to secondary reflector, designed uniquely. All the light rays will then be reflected from the secondary reflector to the solar cell. This will be basically used to pass the maximum captured sunlight on receiver (solar cell). Different quantities will be measured using LightTools®. The concentration module based on this design will be an optimistic option for the development of the economic photovoltaic solar energy generation.
