How do solar panels work wikipedia

Photons strike and ionize semiconductor material on the solar panel, causing outer electrons to break free of their atomic bonds.

Due to the semiconductor structure, the electrons are forced in one direction creating a flow of electrical current. Some of the light spectrum is reflected, some is too weak to create electricity infrared and some ultraviolet creates heat energy instead of electricity. Diagram of a typical crystalline silicon solar cell. The resulting structure creates a pathway for electrical current within and between the solar cells. The PV effect was observed as early as by Alexandre Edmund Becquerel, and was the subject of scientific inquiry through the early twentieth century.

In , Bell Labs in the U. The energy crisis of the s saw the beginning of major interest in using solar cells to produce electricity in homes and businesses, but prohibitive prices nearly 30 times higher than the current price made large-scale applications impractical. Industry developments and research in the following years made PV devices more feasible and a cycle of increasing production and decreasing costs began which continues even today.

Rapidly falling prices have made solar more affordable than ever. The shadow of ships and asteroids can potentially render the panels useless, while glass panels will only partially reduce solar exposure. The power grid gives priority to use of solar power, therefore any reactors on the same ship or station can remain active, but will only consume uranium once the power draw exceeds the capacity of both the solar panels and the discharging Batteries.

A Solar Panel attached to a large ship produces a maximum of kW when aimed directly at the sun. The small ship version can reach only 30 kW. The maximum output listed in the control panel indicates its potential output at the current angle, as it takes a short time for them to warm up.

One Panel with full production will produce enough energy to supply a Medical Room , meaning that you are theoretically independent from uranium in order to survive. One Assembler , one Refinery and one Gravity Generator will use up to 1, Metal conductive plates on the sides of the cell collect the electrons and transfer them to wires. At that point, the electrons can flow like any other source of electricity.

Recently, researchers have produced ultrathin, flexible solar cells that are only 1. In fact, the cells are so light that they can sit on top of a soap bubble , and yet they produce energy with about as much efficiency as glass-based solar cells, scientists reported in a study published in in the journal Organic Electronics. Lighter, more flexible solar cells such as these could be integrated into architecture, aerospace technology, or even wearable electronics.

There are other types of solar power technology — including solar thermal and concentrated solar power CSP — that operate in a different fashion than photovoltaic solar panels, but all harness the power of sunlight to either create electricity or to heat water or air.
