With the rapid increase in energy demand and the rise of CO2 levels due to traditional energy production from fossil fuels, it is critical to the transition to a sustainable and renewable energy sources. Recently, photovoltaic technology has been raised as a promising alternative to fossil fuel energy production. Solar cells, predominately crystalline silicon technology, are currently 3.6% of electricity production. To maintain this progress, coupling the perovskite and silicon in tandem devices has enormous potential to increase the efficiency of solar energy production, where perovskite solar cells emerged as a promising technology. Textured silicon solar cells are a well-established technology; keeping the advantage of this technology, it is crucial to employ the perovskite to be a compatible top cell for silicon-based tandems.
Here, we optimize the silicon bottom cell by understanding the influence of temperature, time, and etchant concentration on the optical properties and performance of the device. Then, we investigate the impact of the textured silicon on the optoelectronic properties of perovskite. Using hyperspectral imaging, we demonstrate that different texturing substrates influence the PL of perovskite, which is associated with the thickness of the perovskite. Lastly, we explored the delamination of the devices due to the weak adhesion between C60/SnO2 after the deposition of IZO and MgF2, which was found to be caused by the deposition conditions. The high temperature and power density caused a weak adhesion between C60/SnO2. Overall, these findings will help to alter the design of Perovskite/Silicon tandem devices to accelerate the commercialization of tandem technology.
