In printable mesoscopic perovskite solar cells (PSCs), carbon electrodes play a significant role in charge extraction and transport, influencing the overall device performance. The work function and electrical conductivity of the carbon electrodes mainly affect the open-circuit voltage ( VOC) and series resistance ( Rs) of the device.
Carbon-based perovskite solar cell development faces a challenge in modifying its electrode's work function for hole extraction and transport. To overcome this, we optimized the carbonization process, resulting in a dendritic graphite surface extension structure that increased photovoltaic conversion efficiency from 15.16 % to 18.19 %.
B.Y. and J.S. have manufactured the samples for analyzing the properties of perovskite solar cells with low-temperature carbon-based contacts (L-CPSCs). D.Ma., S.N., and A.V. have manufactured the samples for analyzing the properties of perovskite solar cells with high-temperature carbon-based contacts (H-CPSCs).
The released electrons then move through an electron transport layer (ETL), facilitating their transport towards the battery. At the interface between the perovskite solar cell and the LIB, an electrolyte or electrolyte medium is present, allowing the migration of lithium ions.
Precisely, we focus on Li-ion batteries (LIBs), and their mechanism is explained in detail. Subsequently, we explore the integration of perovskites into LIBs. To date, among all types of rechargeable batteries, LIBs have emerged as the most efficient energy storage solution .
Futures 2 022101 DOI 10.1088/2752-5724/acbbc2 Towards commercialization of perovskite solar cells (PSCs), further reducing the cost and increasing the stability of PSCs have been the most important tasks of researchers, as the efficiency of single-junction PSCs has reached a competitive level among all kinds of single-junction solar cells.

In addition, theoretical simulation and experiments show that the matching of electrode and perovskite layer is also very important. Au has a suitable work function to match CsPbIBr 2, but the high price limits the application of Au; the price of Ag is relatively low, but Ag can be diffused into PSC, resulting in device degradation this case, carbon with a good …

Carbon-Based Electrodes for Perovskite Photovoltaics
When these devices were tested under high thermal stress of 100 and 150 °C, 3D perovskite/carbon device retained 85% of the initial PCE and 3D/2D perovskite/carbon shows PCE 102% of the initial value. This is because the 2D interlayer prevented the ion migration and PEAI in the carbon electrode suppressed the thermal decomposition. On the other hand, the …
