Query: Modeling of high-efficiency silicon solar cells in realistic operating
  conditions   The selfconsistent model for the temperature dependence of photoconversion
efficiency $\eta$ for highly efficient silicon solar cells (SCs) is developed.
It is demonstrated that effect of the efficiency decrease due to increasing
temperature is less pronounced in the SCs with lower surface recombination
velocity, thus offering a possibility to improve the cells' performance.
  The photoconversion efficiency of the high efficiency silicon solar cells is
modeled for the realistic ambient conditions. The SC operating temperature is
determined by self-consistently solving the photocurrent, photovoltage, and
energy balance equations, considering both radiative and convective cooling
mechanisms. The SC temperature is shown to be substantially higher than the
ambient temperature even at very high convection coefficients, such as, e.g.,
300 $W / (m^2 \cdot K)$, used in our examples. The photoconversion efficiency
for this case is substantially below the efficiency of thermally stabilized SC,
for which the operating temperature is close to the external temperature.
  The open-circuit voltage and photoconversion efficiency of the high-quality
silicon solar cells under concentrated illumination are also investigated
including the tradeoff between SCs heating and cooling processes.
