What is a solar concentrator module?
Sandia Labs and MIT developed a concentrator module comprising a three-stage optical system. Various iterations were published. The first prototype involves a molded PMMA array of micro-lenses concentrating sunlight onto hexagonal silicon solar cells, achieving a concentration ratio of 36X. [ 107]
Does solar cell efficiency increase under concentrated light?
Theoretically, the efficiency of a solar cell increases slightly under concentrated light as shown in eqn (10) because both output and input energies increase due to solar concentration. However, this is not the case as losses occur within the solar cell due to the cell series resistance (Rs).
How does a solar concentrator unit work?
The concentrator unit was fabricated by incorporating an optical element on top of the solar cell and bonding it using a UV curable optical adhesive. Enough adhesive is applied on the base of the concentrator unit and then it is immediately placed on the solar cell surface.
How does solar concentration affect electrical efficiency?
Ideally, the electrical efficiency of the cell should increase with solar concentration, but losses caused due to internal resistances tend to decrease the power output substantially, which means there is an optimum level of solar concentration that a specific design of solar cell would be able to achieve.
How do solar cell concentrator lenses work?
