From the earliest days of solar-powered satellites to modern rooftop arrays and utility-scale solar farms, this is the complete history of solar energy—and a look at its exciting potential in the years to come. The story of solar energy begins in 1839 with the work of French physicist Edmond Becquerel.
• 1954 - Bell Labs announces the invention of the first modern silicon solar cell . These cells have about 6% efficiency. The New York Times fo recasts that solar cells will eventually lead to a source of "limitless energy of the sun." • 1955 - Western Electric licences commercial solar cell technologies.
In the late 1700s and 1800s, researchers and scientists had success using sunlight to power ovens for long voyages. They also harnessed the power of the sun to produce solar-powered steamboats. Ultimately, it's clear that even thousands of years before the era of solar panels, the concept of manipulating the power of the sun was a common practice.
In 1966, NASA launched the world's first Orbiting Astronomical Observatory, powered by a one-kilowatt array. In 1973, the University of Delaware was responsible for constructing the first solar building, named "Solar One." The system ran on a hybrid supply of solar thermal and solar PV power.
This period began with the success of the first Telstar communication satellite launched in 1962 and powered by silicon solar cells as shown in figure 1.1a. Then in the 1970s, silicon cells were evolved for use in terrestrial installations. Figure 1.1b shows a typical terrestrial silicon solar cell today.
However, solar cells as we know them today are made with silicon, not selenium. Therefore, some consider the true invention of solar panels to be tied to Daryl Chapin, Calvin Fuller, and Gerald Pearson's creation of the silicon photovoltaic (PV) cell at Bell Labs in 1954.
It has now been 175 years since 1839 when Alexandre Edmond Becquerel observes the photovoltaic (PV) effect via an electrode in a conductive solution exposed to light . It is instructive to look at the history of PV cells since that time because there are lessons to be learned that can provide guidance for the future development of PV cells.

1883 - Charles Fritts develops a solar cell using selenium on a thin layer of gold to form a device giving less than 1% efficiency. [5] 1887 - Heinrich Hertz investigates ultraviolet light photoconductivity and discovers the photoelectric effect; 1887 - James Moser reports dye sensitized photoelectrochemical cell.
(1883) A few years later in 1883, Charles Fritts invented the very first proper solar cell. This rudimentary cell was a thin layer of gold coated substrate with a thin layer of selenium. The resulting efficiency of the first solar cell was at about 1%.
Solar cells: Definition, history, types & how they work. Solar cells hold the key for turning sunshine into into electricity we can use to power our homes each and every day. They make it possible to tap into the sun''s vast, renewable energy. Solar technology has advanced rapidly over the years, and now, solar cells are at the forefront of creating clean, sustainable energy from sunlight.
It has now been 184 years since 1839 when Alexandre Edmond Becquerel observed the photovoltaic (PV) effect via an electrode in a conductive solution exposed to light [1]. It is instructive to look at the history of PV cells [2] since that time because there are lessons to be learned that can provide guidance for the future development of PV cells.

Plotting current vs. voltage for a particular solar cell, array, or module is called its I-V characteristics. Using I-V characteristics, the efficiency and energy conversion ability of a solar cell is calculated. By knowing P max of a solar cell or panel, the performance and solar efficiency of the device can be determined . The current produced in a solar cell is directly …

The three inventors created an array of several strips of silicon (each about the size of a razor blade), placed them in sunlight, captured the free electrons and turned them into electrical current. They created the first solar panels. Bell Laboratories in New York announced the prototype manufacture of a new solar battery. Bell had funded the research. The first …
Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
The history of solar cells involves scientific discovery, invention, and rivalry. We often consider solar power to be a new technology, but it dates back to ancient times. Humans have been using solar energy for light and heat for hundreds of years. Chinese, Greek, and Roman inventors built structures that tracked the sun to capture light and ...
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
In 1959, the US launched Explorer 6 launched with wing-shaped solar arrays consisting of Hoffman solar cells. By 1960, solar cells were the main power source for orbiting satellites and probes. In 1973, Elliot Berman founded Solar Power Corporation, a subsidiary of Exxon, and made huge strides in the cost of solar cell production.
