Perovskite is a mineral and a family of crystalline materials with a specific ABX3 structure, notable for its semiconductor properties used in solar cells and optoelectronic devices. In scientific contexts it denotes a class of compounds with a characteristic crystal lattice, especially the synthetic variants studied for photovoltaics. The term also appears in materials science literature to describe related perovskite phases and derivatives.
"Perovskite solar cells have rapidly improved in efficiency over the past decade."
"Researchers synthesized a new organic–inorganic perovskite to enhance stability in outdoor environments."
"The crystal structure of perovskite enables unique light–matter interactions useful for lasers and LEDs."
"Thermal annealing helped to optimize film formation in the perovskite layer of the device."
The word Perovskite originates from the mineral perovskite (calcium titanate, CaTiO3) discovered in 1839 by Gustav Rose and named after Russian mineralogist Lev Perovski (de: Perovsk) who studied the mineral in 1839. The mineral was named in his honor, with the suffix -ite denoting a mineral or rock. The term later broadened in the 20th century as a family of compounds sharing the same ABX3 crystal structure (where A and B are cations and X is an anion). In modern materials science, “perovskite” refers to artificial crystal systems mimicking CaTiO3, including organic–inorganic lead halide variants used in solar cells. First known use in a scientific sense to describe the mineral dates to the 19th century; its application to a class of functional materials emerged in the late 20th and early 21st centuries with advances in perovskite photovoltaics and light-emitting applications.

🎵 Rhyme tip: Practicing with rhyming words helps you master similar sound patterns and improves your overall pronunciation accuracy.
Pronounce as /ˌpɛrəvˈskaɪt/ in US/UK/AU. The primary stress lands on the third syllable 'skaite' (/ˈskaɪt/). Break it into pe-roe-vskite with a light initial, a clear ‘roe’ as /rə/ or /rɔː/ in some accents, and end with /skaɪt/ (rhymes with 'bite'). Visualize: per-OV-skite, with emphasis starting on the second syllable and releasing into the final /skaɪt/. For audio reference, listen to standard English pronunciations of ‘perovskite’ in technical lectures and dictionaries.
Common errors include: 1) Shifting stress to the first syllable (PÉ-ro-vskite) or splitting ‘skaite’ as two sounds; 2) Pronouncing the middle syllable as /roʊ/ or /roʊv/ rather than /rəv/; 3) Ending with a soft ‘skite’ that lacks final crisp aspiration. Correct these by emphasizing /rəv/ and finishing with /skaɪt/, keeping the aura of technical precision. Practice with minimal pairs like ‘perovskite’ vs ‘perovskite-like’ and compound terms to lock the final /aɪt/ diphthong.
In US/UK/AU, the strongest difference is vowel quality in the first unstressed syllable and the rhoticity. US tends to be rhotic with /ˈpɛrəvˌskaɪt/ where /r/ is pronounced; UK often features non-rhotic tendencies in careful speech, giving a subtler /ˈpɛrəvˌskaɪt/ with weaker post-vocalic r; AU generally aligns with rhotic norms but may reduce some vowels slightly, keeping /ˈpɛrəvˌskaɪt/ in many scientific contexts. The final /skaɪt/ remains consistent across accents.
Two main challenges: 1) The sequence /rəv/ in the middle can blur, especially before a stressed /ˈskaɪt/ ending; maintain a crisp /r/ or rhotic approximant and avoid vocalizing the /ə/ too long. 2) The final /skaɪt/ blends quickly; practice a firm /s/ + /k/ + /aɪ/ + /t/ without an intrusive vowel. Overall, keep the stress on the second syllable’s onset and deliver a clean coda /t/.
No silent letters in standard pronunciation. Each letter participates in the phoneme sequence /ˌpɛrəvˈskaɪt/. The tricky part is not silent letters but the multi-syllabic rhythm and the consonant cluster at the syllable break (/r-/ and /v/ before /skaɪt/). Keeping the syllable boundary clear—per-ov-skite—helps avoid run-together speech.
