Abstract
Using a lens to concentrate sunlight and focus it on smaller sized solar cells increases the system’s output power and in the same time decreases the cost by replacing much of the expensive semiconductor photovoltaic cells with the cheaper optics. But the concentrated light will raise the temperature of the photovoltaic cell and that may affect the performance hence, will affect the output power of the CPV unit[1]. A CPV unit with a dynamic lens has been developed and manufactured. Light dependent resistors (LDR) were used to collect data then according to the electrical circuit the dynamic lens moves in a way that makes sure that the optimal intensity of the sunlight falling on the photovoltaic cell is achieved, hence we can gain an enhanced electrical output power. The developed CPV unit with the dynamic lens has been used for evaluating the voltage in the open circuit case and compare it with a fixed lens CPV unit under the same conditions.
