cpv

CPV is an acronym that can refer to more than one concept depending on the context. The two most common modern uses are concentrating photovoltaics in solar power and cost per view in online advertising.

Concentrating photovoltaics uses optical elements such as Fresnel lenses or mirrors to focus sunlight onto small, high-efficiency solar cells. The approach increases the electrical output per unit of PV material and often employs tracking systems to maintain alignment with the sun. CPV installations are typically used in utility-scale projects and desert or high-irradiance locations. Advantages include higher cell efficiency and reduced PV material per watt; challenges include higher upfront costs, greater cooling requirements, and more complex optics and tracking mechanisms. The technology depends on advanced multijunction solar cells to capture multiple wavelengths of light.

Cost per view is an online advertising pricing model where advertisers pay when a video advertisement is viewed by a user. A 'view' is typically defined by a minimum engagement threshold set by the platform, such as watching a certain portion of the video. CPV contrasts with cost per thousand impressions (CPM) or cost per click (CPC) models. It is commonly used in video platforms and social media campaigns, with pricing influenced by audience targeting, video quality, and ad quality signals. Critics note that measured views may include brief or non-engaged views, so publishers and advertisers should consider viewability and brand safety.

Other domain-specific meanings may exist; CPV should be interpreted from context.
