Influence of selective contact layers and interfacial treatments on efficiency and stability of perovskite solar cells

Scheler, Florian (author), Topič, Marko (mentor)

There is an urgent need for renewable energy technologies that are affordable and can be deployed mrapidly to mitigate climate change. Global average temperatures surpassed the 1.5 ∘C mthreshold for the first time in 2024, underscoring the shortcomings of current mitigation strategies mand reinforcing the demand for scalable, high-efficiency energy solutions. Owing to substantial mcost reductions over the past decade, photovoltaics (PV) have become the most cost-effective source of electricity in many parts of the world. However, further cost reductions through improvements in device performance and operational lifetime are required to meet global deployment targets.

• Title: Vpliv selektivnih kontaktnih plasti in obdelave spojev na učinkovitost in stabilnost perovskitnih sončnih celic

Abstract

Doktorska disertacija obravnava temeljne in praktične izzive pri izboljševanju učinkovitosti in dolgoročne stabilnosti perovskitnih sončnih celic (PSC), zlasti v tandemski konfiguraciji. Motivacija izhaja iz nujne potrebe po obnovljivih energetskih tehnologijah, ki jih je mogoče hitro razširiti za spopadanje s podnebnimi spremembami. Leta 2024 so globalni temperaturni rekordi presegli prag 1,5 °C, kar potrjuje neučinkovitost obstoječih strategij za ublažitev podnebnih sprememb in povečuje pritisk na uvedbo cenovno dostopnih, visoko učinkovitih rešitev za pretvorbo in shranjevanje energije.
