La perovskite (talvolta perowskite) è un minerale costituito da titanato di calcio. Il nome deriva dal grande collezionista di minerali russo Perovskij, e venne attribuito a cristalli opachi di forma cubica trovati dal mineralogista tedesco Gustav Rose nel 1839 ad Achmatovskaja, nei Monti Urali russi .
Since its introduction in 2009, photoconversion efficiencies (PCE) of perovskite solar cells has hiked from 3.9% to 25.8% by 2021. Despite the swift increase in PCE, perovskite …

Rohelise energia tootmine on üks suurimaid keskkonnasõbralikke muutusi, mida oma elus teha. Päikesepaneelide abil vähendad enda ökoloogilist jalajälge, hoiad kokku elektrikuludelt ja saad elektrit tagasi võrku müüa. Et toodetud energiat maksimaalselt ära kasutada, soovitame lisaks paneelidele soetada ka energiasalvesti.
Light-emitting diodes based on halide perovskites have undergone rapid development in recent years and can now offer external quantum efficiencies of over 23%. However, the practical application ...
We demonstrate a monolithic perovskite/CIGS tandem solar cell with a certified power conversion efficiency (PCE) of 24.2%. The tandem solar cell still exhibits photocurrent mismatch between the subcells; thus optical simulations are used to determine the optimal device stack. Results reveal a high optical potential with the optimized device reaching a …
