Summary: The material iron pyrite (FeS2) has great potential for solar cell applications due to its high absorption coefficient and low cost. However, its efficiency is still relatively low at around 2.8% due to the presence of an acceptor-type surface inversion layer (SIL) with a significant band gap. This study provides a comprehensive analysis of the band gap and doping variation of SIL, suggesting that a higher band gap of 0.72 eV and a doping of 10(19) cm(-3) can achieve a conversion efficiency of 5.36% in FeS2 solar cells.

Summary: Perovskite solar cells exhibit high radiative efficiency, long carrier lifetimes, and high carrier mobilities. However, Auger recombination losses significantly limit their V-OC below the Shockley-Queisser limit. By analyzing the effects of Auger capture coefficients in mixed-cation perovskites, it is shown that increasing the acceptor concentration and Auger capture coefficients drastically reduce V-OC and FF, leading to a decrease in device performance. The findings suggest that the Auger recombination coefficients should be less than 10(-24) cm(6) s(-1) to improve the efficiency of perovskite solar cells and mitigate the effects of Auger recombination.

The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
