Reflection and Transmission of Radiation of the Structure Crystalline Silicon–Black Silicon–Perovskite

The reflection and transmission of crystalline silicon-black silicon-perovskite structures in the absence of optical losses have been investigated by the matrix transfer method. Analytical expressions for the reflection and transmission coefficients are obtained. Low values of transmittance and high values of reflection in the visible region of the spectrum are obtained. It is shown that the use of black silicon layers for the decreasing of the transmission for two-terminal tandem perovskite-silicon solar cells is promising.
