Jan 1, 2013 · Solar cell performance decreases with increasing temperature, fundamentally owing to increased internal carrier recombination rates, caused by increased carrier concentrations.
The decrease in the efficiency of m-Si cells and thin film cells are observed to be about 15% and 5%, respectively, as the module temperature rises from 300 K to 330 K. Currently, most of the growth in solar PV utilization is mono c-Si and poly c-Si technologies (Fig. 2), which are the PV types for which is most affected by module temperature.
The efficiency of a solar cell is the ratio of delivered output power to the global radiation and module area. The performance of the PV systems depends on the power output, which is related to cell characteristics and ambient conditions. Some factors which affect the output of the PV system are explained below.
Photovoltaic modules (Figure 2) are interconnected solar cells designed to generate a specific voltage and current. The module's current output depends on the surface area of the solar cells in the modules. Figure 2. A flat-plate PV module. This module has several PV cells wired in series to produce the desired voltage and current.
The efficiency of PV modules is determined by how well they convert solar power to electrical power, influenced by factors like sunlight intensity and cell temperature.

Martin Green describes the Solar Cell Efficiency Tables that have been providing 6-monthly updates of record solar cell performance since the 1990s. Keeping track of the rapidly improving solar cell performance is not as easy as it seems.
The efficiency of a solar cell is determined as the fraction of incident power which is converted to electricity and is defined as: η is the efficiency. The input power for efficiency calculations is 1 kW/m 2 or 100 mW/cm 2. Thus the input power for a 100 × 100 mm 2 cell is 10 W and for a 156 × 156 mm 2 cell is 24.3 W
