The efficiency of a solar cell is determined as the fraction of incident power which is converted to electricity and is defined as:P max =VOCI SC FF where V oc is the open-circuit voltage;where I sc is the short-circuit current; andwhere FF is the fill factorwhere Î·is the efficiency.
As seen from the Earth, a solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks (occults) the Sun. This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy.
Best Answer: A solar eclipse happens when the moon moves between the earth and the sun. In that case, the sunlight hits the moon on the side away from the earth, and the side towards the earth is dark. This means that the moon phase is 'new'. A lunar eclipse happens when the earth moves between the sun and the moon. In that case, the sunlight hits the moon on the side toward the earth and the phase is 'full'.
