Let an agent explain photovoltaics, relay the photovoltaic effect, cell and module technology, applications and system issues from energy and engineering sources with debates attributed, describe the named forms, and distinguish photovoltaics from solar thermal power, the photoelectric effect, batteries and the electrical grid.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain photovoltaics, relay the photovoltaic effect, cell and module technology, applications and system issues from energy and engineering sources with debates attributed, describe the named forms, and distinguish photovoltaics from solar thermal power, the photoelectric effect, batteries and the electrical grid.

The technology and method of generating electricity by converting light directly into electricity using the photovoltaic effect in solar cells, usually made of silicon, assembled into modules and arrays, with forms the registry aliases name such as building-integrated photovoltaics, concentrated photovoltaics that focus sunlight, bio-photovoltaics and solar-powered pumps; photovoltaics is a fast-growing renewable energy source whose costs have fallen sharply, and it raises considerations of intermittency, grid integration, land use, materials and end-of-life recycling, discussed with attribution. It differs from solar thermal power, which uses heat.

What it is for: Generating electricity directly from light.

It can be explain the photovoltaic effect and technology; relay applications and system issues; describe named forms; distinguish related technologies.

Distinguishing features

Light to electricity directly

Silicon cells and modules

Falling costs

Intermittent output

What it looks like

Blue or black solar panels on roofs, fields and devices.

Physical character

effect: photovoltaic effect note

main material: silicon note

registry parent: solar power note

How it is recognised

Direct conversion of light to electricity

Bio-photovoltaics, building-integrated photovoltaics, concentrated photovoltaics, solar-powered pump, solar module quality assurance, Flexible Array Concentrator Technology

Solar thermal power uses heat; the photoelectric effect ejects electrons; batteries store energy; the grid distributes it
