Perovskite-based solar cell for space application

Objetivo

Perovskite solar cells (PSCs) are promising candidates for space applications; however, the space environment involves harsh conditions such as radiation exposure and temperature cycling. Thermal cycling experiments on PSCs have revealed changes in the phase transitions of the perovskite absorber layer. It is also well established that proton irradiation introduces defects in PSCs, which can either enhance or degrade device performance depending on the material system.

To evaluate PSC operation under combined radiation and thermal stress, systematic testing is required under controlled temperature variations and irradiation exposure. In this study, PSCs will first undergo thermal cycling and subsequently be subjected to proton irradiation in order to analyze the effects of both conditions in combination. Advanced experiments are therefore essential to understand the fundamental performance and stability of PSCs in such extreme environments.

In this project, we propose in-situ J–V measurements under AM0 solar spectrum conditions during proton irradiation (68 MeV) using the cyclotron facility at HZB. Complementary material characterization and device physics measurements will be conducted to gain insights into defect formation, phase stability, and performance evolution. The host group, led by Dr. Felix Lang at the University of Potsdam, is internationally recognized for its pioneering work in PSC development and possesses unique expertise in device engineering. The project will generate industrially relevant strategies for improving PSC robustness, which are critical for their deployment in space applications.
