**Modeling of an equivalent circuit for dye-sensitized solar**

Equivalent electric circuit A solar module can be seen as a black box that with two connectors, producing a current, I , at a voltage, U . For the purpose of the electrical characteristics of a solar cell, the inside of that black box can be described by an electric cicuit with only 4components:... parameters, solar cells with optimized PV conversion efficiencies in excess of 8% can be achieved, with open- circuit voltages V OC in the region of 500-550 mV [1]. As SC is varied either side of this optimum concentration there is a reduction in solar cell efficiency.
