Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
The first solid‐state solar cells, fabricated ≈140 years ago, were based on selenium; these early studies initiated the modern research on photovoltaic materials.
The solar cell''s ability to convert sunlight into electricity can be broken down into four main steps: Absorption of Sunlight: For a solar cell to function and generate electricity, it first needs to absorb sunlight. The cell is made up of a semiconductor material, commonly silicon, which has the ability to absorb photons (particles of light ...

Tervo et al. propose a solid-state heat engine for solar-thermal conversion: a solar thermoradiative-photovoltaic system. The thermoradiative cell is heated and generates electricity as it emits light to the photovoltaic cell.

In the lab, perovskite solar cell efficiencies have improved faster than any other PV material, from 3% in 2009 to over 25% in 2020. To be commercially viable, perovskite PV cells have to become stable enough to survive 20 years outdoors, so researchers are working on making them more durable and developing large-scale, low-cost manufacturing ...

These cells were first discovered in the 19th century, but they''ve come a long way since then. Made mostly from silicon, a material found in sand, PV cells work by capturing light particles called photons. When these photons hit a PV cell, they knock electrons loose, creating an electrical current.
