It is found that at low irradiance intensity the performance of compensated crystalline silicon solar cells is relatively worse than that of the reference silicon solar cells, while at high temperature it is relatively better than that of the reference silicon solar cells.
It suggests that compensated silicon might be more acceptable for the future of PV industry since the temperature of PV modules is generally higher than 25 °C under real working conditions.

At low irradiance intensity, compensated silicon solar cells show relatively worse performance than the reference silicon solar cells, which has been explained by the strong injection dependence of the carrier lifetime due to the existence of high concentration of B–O complexes in compensated silicon.
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 upon the operating temperature. Solar cells vary under temperature changes; the change in temperature will affect the power output from the cells.
For the same rated output power, compensated crystalline silicon solar cells generate less electricity than the reference silicon solar cells at low irradiance intensity, owing to the strong injection dependence of the carrier lifetime due to high concentration of B–O complexes in compensated silicon.
At the same operating temperature, silicon (Si) heterojunction (SHJ) cells with a relative TC η of −0.29 %/°C present an efficiency of 18.70% [ 3 ], yielding a 0.51% absolute higher efficiency than that of the PERT cells. In general, the performance of Si-based solar cells is reduced at elevated temperatures [ 5 ].
