Tandem solar cells with a perovskite top cell and crystalline silicon (c-Si) bottom cell have reached certified efficiencies of 28% (on 1 cm2 by Oxford PV) in just about 4 years. This success is mainly attributed to the optimized design in the perovskite top cell and the crystalline silicon bottom cell.
The composition of the perovskite active layer and the thickness of functional layers were the same as that used in 1 cm 2 ST-PSCs. The large-area ST-PSC was placed on the top of the hybrid BC silicon solar cell as a filter, and the remaining light traveled through the ST-PSCs was absorbed by the silicon solar cell.
A matched JSC was observed in the external quantum efficiency (EQE) spectra of the perovskite top cell and the silicon bottom solar cell (Fig. 4g). We reconstructed the surface structure of perovskite films using the surface reconstruction method and obtained ultra-smooth surfaces.
The semitransparent perovskite cell integrated to 17.3 mA/cm2 when illuminated through the TiO2 layer. However, the EQE was only 11.4 mA/cm2 when illuminated through the spiro-OMeTAD layer. There are no front texturing and passivation for the silicon bottom cells.
Our review will emphasize the important role of the C-Si bottom cell with different passivation structures for perovskite/silicon tandem cells, which provides a guidance to enhance the performance of tandem cells.
