The sunlight is a group of photons having a finite amount of energy. For the generation of electricity by the cell, it must absorb the energy of the photon. The absorption depends on the energy of the photon and the band-gap energy of the solar semiconductor material and it is expressed in electron-volt (eV).

This is known as the power conversion efficiency (PCE) and is the ratio of incident light power to output electrical power.
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 power output of solar modules can be boosted by 10% just by applying a large transparent sticker to the front. The sticker is a polymer film embossed with microstructures that bend incoming sunlight. The result is that the active materials in the panels absorb more light and convert more of it into electricity.
A solar cell efficiency is defined as the maximum output power (PM) divided by the input power (PIN). It is measured in percentage (%), which indicates that this percentage of input sunlight power is converted to electrical power. The input power is power density. Therefore, to calculate efficiency multiply PIN at STC by area.
The power output at the maximum power point under strong sunlight (1 kW/m2) is known as the ‘peak power’ of the cell. Hence photovoltaic panels are usually rated in terms of their ‘peak’ watts (Wp). The fill factor (FF), is a measure of the junction quality and series resistance of a cell. It is defined as
