Photovoltaic windows are (semi)transparent modules that can be used to replace a number of architectural elements commonly made with glass or similar materials, such as windows and skylights. In addition to producing electric energy, these can create further energy savings due to superior thermal insulation properties and solar radiation control.
CIGS is a I-III-VI 2 compound semiconductor material composed of copper, indium, gallium, and selenium.The material is a solid solution of copper indium selenide (often abbreviated "CIS") and copper gallium selenide, with a chemical formula of CuIn x Ga (1−x) Se 2, where the value of x can vary from 1 (pure copper indium selenide) to 0 (pure copper gallium selenide).
The selective contacts (also referred to as the "window layers") are then similarly formed by deposition of the p-and n-type highly doped amorphous silicon layers. [ 71 ] [ 72 ] Examples of dopant gases include phosphine (PH 3 ) for n -type and trimethylborane (B(CH 3 ) 3 ) or diborane (B 2 H 6 ) for p -type. [ 73 ]
The smallest, often portable photovoltaic systems are called pico solar PV systems, or pico solar. They mostly combine a rechargeable battery and charge controller, with a very small PV panel. The panel's nominal capacity is just a few watt-peak (1–10 W p ) and its area less than 0.1 square metres (1 sq ft) in size.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
From a solar cell to a PV system. Diagram of the possible components of a photovoltaic system. Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor ...

According to energyinfomative.org, the average cost for a residential solar system is between $15,000 and $40,000 (USD), and about $7 per watt. [11] In the article, it says that at today's rates, it would take 10 years to pay off an average system. As a solar panel may last more than 20 years, [12] in the end, it becomes a benefit.
