PV output temperature characteristics of the temperature rise will affect PV open circuit voltage drop, short-circuit current is increased slightly, with the photovoltaic cell photovoltaic junction temperature rise cooperation to join, its maximum output power declining, its efficiency as the temperature The rise and fall of photovoltaic power generation investment cooperation, namely photovoltaic cell having a negative temperature coefficient. For the commonly used silicon and polysilicon for photovoltaic power generation cooperation dealers, as the temperature increases the voltage, fill factor FF and efficiency have different degrees of decline. Overall, when the temperature rises rated power output of photovoltaic cells also declined slightly, ambient temperature level will have a direct influence on the maximum output power Hing volt battery. Solar thermal power generation is the first solar energy into heat, then heat into electricity, it has two conversion mode. One is the direct conversion of solar energy into electrical energy, such as a semiconductor or metal material temperature difference power generation, vacuum devices in the hot electron and ion thermal power generation, AMTEC, and MHD power generation. Another way is to drive the generator to generate electricity through solar thermal heat engines (such as steam turbines), and conventional thermal power generation similar, but not its heat from the fuel, but from solar energy.
