When used with a photovoltaic solar panel, these types of silicon diodes are generally referred to as Blocking Diodes. Bypass Diodes are used in parallel with either a single or a number of photovoltaic solar cells to prevent the current(s)

Fenice Energy is leading the way. They''re working on new ways to use solar power to cut down CO₂ emissions. For example, a home solar panel system can save about 200,000 lbs of CO₂ in 25 years. India is following
Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
Diodes are extensively used in solar panel installations. Since the prevent backflow of current (unidirectional flow of current), they are used as blocking devices. They are also used as bypass devices to maintain the reliability of the entire solar power system in the event of a solar panel failure.
However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance. A straight-forward method of estimating the series resistance from a solar cell is to find the slope of the IV curve at the open-circuit voltage point.
Therefore, the two main types of diodes used in a solar system are: A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from battery to solar panel thereby preventing the battery from discharging.
However the shunt resistor is connected in parallel to diode. That means "higher the shunt resistor greater the current output". How and why so? I thought not having many grain boundaries is what makes the monocrystalline cells more efficient than polycrystalline solar cells?!
In the circuit equivalent of a solar cell, shunt resistor is described as "The irregular polycrystalline lattice grain boundaries that resist to the flow of electrical current in the silicon material." If this explanation is correct, shouldn't it be "lower shunt resistance increases the current flowing".
