When the operating temperature increases, the efficiency of the photovoltaic panel is reduced almost linearly. Figure 23. Variation of the efficiency of the PV panel with the operating temperature for G med = 520 W/m 2. Figure 24, Figure 25 and Figure 26 represent the coefficients of variation of PV panel parameters with temperature.
The organic phase change material (melting point range 37 °C to 42 °C) was utilized to store thermal energy on the backside of the photovoltaic module. A sheet and tube type absorber was constructed with a spiral-shaped cooling water circulation channel within a PCM container to extract the stored heat.
The operating temperature plays a key role in the photovoltaic conversion process. Both the electrical efficiency and the power output of a photovoltaic (PV) module depend linearly on the operating temperature.
Coventry et al. analyzed the temperature change of a single PV system. The internal temperature of the cell showed that there was a temperature difference of up to 287.15 K between the middle and the edge of the cell. The uneven illumination strongly affects the temperature distribution on the SC.
The study results show that using the TMPL system can effectively eliminate the heat generated by the photovoltaic cells, thereby enhancing both temperature stability and efficiency of the cells. As shown in Fig. 21 b, the LCPV-TMPL system utilizes four photovoltaic cells with a diameter of 10 mm and a length of 5 m in the case study area.
Considering from the perspective of light, the increase in temperature is beneficial to PV power generation, because it will increase the free electron–hole pairs (i.e., carriers) generated by the PV effect in the cell to a certain extent . However, excessively high temperature cannot increase the final output of the SC.
