3. Influence of temperature
The FF was determined by the following equation (4):
\(FF=\frac{I_{m}.V_{m}}{J_{\text{sc}}.V_{\text{oc}}}\) (4)
Where Im and Vm are the photocurrent and the photo voltage for the maximum power, respectively, and Jsc is the courant short-circuit and Vocis the open circuit voltage. We obtained the η parameter using the equation (a):
\(\eta=\frac{J_{\text{sc}}.V_{\text{oc}}\text{.FF}}{P_{\text{in}}}\)(5)
