Improvement of Conversion Efficiency and Enhancement in Output Power of Solar Panel

Concentrating photovoltaics (CPV) is used to integrate the extraction of light energy and thermal energy. The water cooling system is proposed in this paper provides an effective cooling by circulating cold water to remove heat from the PV systems. The use of a water circulation cooling system improves photovoltaic power systems 2 % to 15 % and increases the efficiency of electricity production of photovoltaic 2.29 % - 3.37 %. Through the combined use of photovoltaic and thermal techniques, the total energy of the entire system can be improved by 37 % -59 %, even taking into account the cooling system power consumption. A solar hybrid system is designed to use novel photovoltaics (PV), thermoelectric modules (TE), and hot water (HW) through a multilayer of the building envelope. Water pipes are cast into a functionally graded material layer to serve as a heat sink, which allows because heat water easily transfer through some surface rich in aluminum, while being isolated by a polymer rich background. Compared to traditional solar panels, this design can achieve efficiencies with increased production of electricity and the use of thermal energy. Based on the limitations of the theoretical conversion efficiency, PV / TE / HW system exceeds PV / HW and traditional photovoltaic systems with 30 % more output power.
