Is It Photovoltaic Or Pv?

Photovoltaic (PV) and PV are common terms used to refer to solar panels or solar photovoltaic systems. Both terms have the same meaning, referring to solar panels that convert sunlight into electricity using the photovoltaic effect. The terms are often used interchangeably, though there are some minor differences in usage and preferences between the two forms.

Full Forms

The term photovoltaic, commonly abbreviated as PV, refers to the direct conversion of light into electricity using semiconducting materials. It is most commonly used in reference to solar cells, which absorb sunlight and generate electricity through the photovoltaic effect.

The full form PV stands for “photovoltaic.” It refers to the process of converting light (photo) into voltage (voltaic), which is the operating principle behind solar panel technology. The photovoltaic effect was first observed by French physicist Edmond Becquerel in 1839.

Historical Origins

The terms “photovoltaic” and “PV” were both first coined in the 1950s as researchers began exploring the potential for converting sunlight directly into electricity using semiconductor materials. In 1954, researchers at Bell Laboratories in the United States created the first practical silicon photovoltaic cell. Shortly after, the terms “photovoltaic” and the abbreviation “PV” began appearing in research papers and publications to refer to this new solar cell technology.

The term “photovoltaic” comes from the Greek word for light, “photo,” and “voltaic,” referring to electricity. So it literally means “light-electricity.” The abbreviation “PV” emerged as a shortened form of the word to make it easier to use, especially in technical and academic writing.

So in summary, “photovoltaic” and “PV” originated in the 1950s with the creation of the first modern solar cells. The terms were coined by researchers to describe the novel photoelectric effect enabled by semiconductor materials, allowing the direct conversion of light into electricity.

Technical Definitions

Photovoltaic (PV) refers to a specific technology that converts sunlight directly into electricity using semiconducting materials. The term “photovoltaic” comes from the Greek words “phos” meaning light, and “voltaic”, meaning electric. From a technical perspective, PV involves photovoltaic cells made up of layers of semiconducting material, usually silicon.

When sunlight shines on a PV cell, the photons are absorbed by the semiconducting material, causing electrons to break free from their atoms. This generates an electric current as the electrons flow through the cell. The electricity generated can then be used to power electrical loads, fed into the grid, or stored in batteries.

Photovoltaics is the direct conversion of light into electricity at the atomic level. It is fundamentally different from other solar technologies that indirectly generate electricity by first converting sunlight into heat or mechanical energy.

Common Usage

Nowadays both PV and photovoltaic are used commonly to refer to solar panel technology that converts sunlight into electricity. However, there are some subtle differences in how the terms are used:

PV is more commonly used in casual conversations and marketing materials. For example, homeowners may refer to “installing PVs” on their rooftop. Solar panel companies may advertise “PV systems for your home.” The abbreviation PV is short, simple, and easy to say.

Photovoltaic is more likely to be used in technical documents, research papers, and by scientists. For example, an engineering article may refer to “photovoltaic cell efficiency.” The full word photovoltaic sounds more technical and precise.

So in summary, PV is more conversational while photovoltaic is more technical. But both refer to the same solar power technology in common usage today.

Language Preferences

There are some noticeable differences in how the terms “photovoltaic” and “PV” are used across languages and regions:

  • In English, “photovoltaic” is more commonly used in formal or scientific contexts, while “PV” dominates in the solar industry and mainstream discussions.
  • The abbreviation “PV” seems far more prevalent in English compared to other languages.
  • In Spanish and French, the full term “fotovoltaico” or “photovoltaïque” is standard, while “PV” is rarely used.
  • German appears to use both “Photovoltaik” and “PV” regularly in different contexts.
  • Asian languages like Chinese, Japanese and Korean utilize translations of the full term “photovoltaic” predominantly.
  • The appropriate terms also vary across different dialects of English. British English seems to prefer “photovoltaic”, while American English uses “PV” more extensively.

In summary, “PV” is more heavily utilized in English, especially in the Americas, while other languages still predominantly use translations of the full term “photovoltaic”. The technical and scientific community also leans towards the fuller terminology.

Industry Preferences

Do any solar companies or groups prefer one term?

When it comes to industry preferences between “photovoltaic” and “PV”, there are some slight leanings towards one term versus the other among certain solar energy companies and organizations:

– Many major solar panel manufacturers and installers, like SunPower, SunRun, and Tesla, tend to favor the abbreviation “PV” in their marketing materials and product descriptions. This may be because “PV” is more consumer-friendly.

– Technical groups and solar industry associations, like the Solar Energy Industries Association (SEIA), tend to use the full term “photovoltaic” more often in white papers, technical documents, and policy recommendations. This is likely because “photovoltaic” conveys greater technical specificity.

– Government agencies and academic institutions seem to use both terms interchangeably, without an obvious preference between “photovoltaic” or “PV”. Their language caters to both technical and general audiences.

– Overall, “PV” appears favored in consumer-facing solar applications, while “photovoltaic” finds more use in research and technical contexts. But both terms are widely accepted and understood across the solar energy sector.

Search Volume Differences

When looking at search volume data from tools like Google Trends, we can compare how often internet users search for “photovoltaic” versus “PV”. This gives us insight into the broader awareness and popularity of each term among the general public.

Analyzing Google Trends data for the United States over the past 12 months, “PV” as a search term has a much higher search volume than “photovoltaic”. On a relative scale where 100 represents peak popularity, “PV” has a value of 73 while “photovoltaic” has a value of only 26.

This suggests that in common web searches, PV is almost 3 times more widely searched for than photovoltaic. The abbreviated “PV” appears to be more familiar to the average person than the full technical name “photovoltaic”. While photovoltaic may be used more often in academic or scientific contexts, PV has gained significantly more mainstream recognition.

Marketers, content creators, and companies in the solar power industry should be aware of this discrepancy. Using the more popular “PV” term may help reach a wider audience, while using “photovoltaic” may appeal to a more technical readership.

Readability and Accessibility

When evaluating the terms photovoltaic and PV in terms of readability and accessibility for general audiences, photovoltaic appears to be the clearer and more readily understood term.

Photovoltaic breaks down into the prefix “photo,” meaning light, and “voltaic,” meaning electricity. This makes the term somewhat self-explanatory – it refers to electricity generated from light. The two parts of the word align with how the technology functions.

In contrast, the abbreviation PV requires some pre-existing knowledge to parse. While commonly used within the solar industry, PV may be obscure to lay audiences encountering it for the first time. Some may find it confusing or unintuitive.

Additionally, the term photovoltaic is more likely to be recognized by screen readers and other assistive devices that aid comprehension for visually impaired or learning disabled users. The full word provides more phonetic clues to its meaning than the abbreviation.

For general explanation and introductions to the public, photovoltaic offers a more transparent, accessible term that aids reader understanding. However, once the concept has been established, PV can be used as shorthand among informed audiences. The recognizability and search volume of both terms can make them viable options in the right context.


Both “photovoltaic” and “PV” refer to the same technology that converts sunlight into electricity using semiconducting materials.
