A collaborative research effort from South Korea has detailed a new approach to constructing back-contact perovskite solar cells. According to a report from pv magazine, the work focuses on engineering the electron transport layer within the cell’s architecture.
The team created a bilayer structure using tin oxide, applied through a spin-coating process. This configuration is intended to improve the alignment of energy levels and the movement of electrical charges while decreasing losses from recombination. The cell is built on a glass base with a patterned indium tin oxide coating. A patterned nickel electrode, processed to form nickel oxide, serves as the hole transport layer. These two transport layers are arranged in an interdigitated pattern at the back of the device, allowing for lateral collection of electrical charges. Insulating and passivation layers were also incorporated to prevent short circuits and protect the material.
In this design, light enters the perovskite absorber directly from the top, unimpeded by front electrodes. The researchers constructed three test devices with variations of the tin oxide layer for comparison. Measurements indicated the device incorporating the bilayer tin oxide structure produced a higher average photocurrent than the other versions. That specific cell also demonstrated a maximum power conversion efficiency of 4.52% and showed improved operational stability, attributed to better control of charge recombination.
The researchers suggest that back-contact perovskite solar cells could be suitable for flexible devices and large-area modules due to their potential efficiency, stability, and scalable design. The study was published in the Journal of Power Sources.
