Designs of Various Hybrid Photovoltaic-Thermal (PV/T) Solar Collectors

One of the crucial factors that affect the popularity of photovoltaic module is its relatively low efficiency. Until today, commercially available photovoltaic module efficiency claimed by manufacturers is from 6 to 16 %. However, the claimed efficiency is at a temperature of 25 °C. In reality, especially for countries with hot weather, their ambient temperature during a sunny day would be more than 35 °C. The rising of the PV temperature will result in the drop of module efficiency. By calculation, it was concluded that, for typical silicon-based PV, the efficiency of the cell would decrease 0.5 % with 1 °C increase in temperature .
