“…People tried to use cheaper process like screen-printing technology and cheaper CZ wafers to make the back contact cells, the SunPower company has been the leader in this field for many years. Bunea et al made the back contact cell for concentration using the standard production processes of SunPower company, the size of the cell was also smaller than that of the common back contact cells made by SunPower company, the efficiency was 23% under 9 suns and 22.5% under 20 suns [73], Sunpower company developed a concentration system of 7 suns based on these cells [74]. Smith et al reported the latest generation 3 back contact cell made by Sunpower company using 121 cm 2 N-type CZ wafers, the highest efficiency reached 25% under 1 sun, which was equal to that of the PERL cell made by Zhao et al [75], the efficiency would reach 26% by decreasing the recombination of carriers further according to Swanson's prediction [76], and the efficiency would be higher under a certain concentration ratio.…”

“…However, we must balance the availability (or cost) and performance in the design of the experimental system. For example, the low-cost and easily accessible polysilicon cell is selected for the cell unit, and the back-contact monocrystalline silicon cell [30] with a higher efficiency might be better choice in future works.…”

a b s t r a c tThe present work developed a spectral splitting hybrid photovoltaic/thermal (PV/T) system based on polypyrrole nanofluid. This hybrid PV/T system can overcome the limitation of temperature in traditional PV/T, and achieve a high-temperature thermal output. In this system, the polypyrrole nanofluid employed in the spectral splitting filter can absorb the solar radiation that can't be efficiently utilized by PV cell unit, and convert it into medium-temperature thermal energy. The principle and methodology of the experimental system design was discussed, and the effect of particle concentration on the performance of system was investigated as well. The present work not only verifies the application potential of polypyrrole nanofluid in spectral splitting PV/T system, but also obtains some important rules on the performance. The results indicate that the temperature of nanofluid and the PV efficiency of cell unit itself increases with the particle concentration, but the thermal efficiency decreases simultaneously. The maximum overall efficiency of this hybrid PV/T system with polypyrrole nanofluid filter was 25.2%, which was 13.3% higher than that without filter. More importantly, the medium-temperature thermal energy can be harvested in such a hybrid system. Furthermore, an optimal particle concentration can probably realize a higher overall efficiency.

“…At low‐to‐medium concentration levels, the use of silicon cells is strongly preferred, due to the high performance‐to‐cost ratio of these devices, especially when converting wavelengths below 1100 nm. Unfortunately, in the current market scenario, there are few industrial groups producing Si solar cells usable under low or medium concentration; Narec Solar Ltd and Sunpower Corp. are two well‐known companies working also on this type of product . For the following estimations, the spectral response of a Si solar cell of 20% of efficiency produced by Narec Solar was considered.…”
