Photoelectric Properties of Solar Cells Based on Perovskites

Here we discuss materials and construction of particular solar cells that could be possible replacement for the current silicon-based photovoltaic cells, and methods of studying their performance. Solar cells based on the general perovskite structure (ABX3) attracted in recent years much attention. These materials, due to the possible variability of both cations and anions in their composition, offer almost endless possibilities for synthetic preparation. For the active layer of a solar cell is often used the CH3NH3PbI3-2Cl2 perovskite structure, i.e., a structure containing an organic component. We have built photovoltaic cells with such an active layer and tested them by static and dynamic methods using the unique photoelectric research instrument by Zahner using the method CIMPS (Controlled Intensity Modulated Photocurrent Spectroscopy)
