The output power of the PV cell is voltage times current, so there is no output power for a short-circuit condition because of VOUT or for an open-circuit condition because of IOUT = 0. Above the short-circuit point, the PV cell operates with a resistive load.
The photovoltaic (PV) cell has been described by non-linear outputs characteristics in current-voltage and power-voltage. This outputs is affected by various effects such as; solar irradiance, temperature, wind and dust. Also, it is depending of the material used in P-N junction and it can vary with ideality factor of P-N junction.
Moreover, the Newton iterative method is used for the non-linear characteristics equation to find the I-V and P-V curves. So, the outputs characteristics of PV cell are affected by several factors such as; change in temperature and solar irradiation.
At the output terminals of the PV cell, voltage and current are respectively denoted V and I. For an open cell, V becomes a potential difference unladen and is known as open circuit voltage (Voc). The current reaches its maximum when the output terminals are short-circuited, and, in this case, it is called the short-circuit current (Isc) .
For an open output, the voltage, VOC is maximum (0.6 V) in this case, but the current is 0 A, as indicated. The output power of the PV cell is voltage times current, so there is no output power for a short-circuit condition because of VOUT or for an open-circuit condition because of IOUT = 0.

The conversion efficiency is a measure of how much incident light energy is converted into electrical energy.
