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 ...
To help you better understand how solar cells came to be, we’ve provided a timeline of the discoveries and inventions that led to their creation. French scientist Edmond Becquerel first discovered the photovoltaic effect in 1839. This process occurs when light is absorbed by a material and creates electrical voltage.
1954 - On April 25, 1954, Bell Labs announces the invention of the first practical silicon solar cell. Shortly afterwards, they are shown at the National Academy of Sciences Meeting. These cells have about 6% efficiency. The New York Times forecasts that solar cells will eventually lead to a source of "limitless energy of the sun".
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 . 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.
2.1.2. The silicon supply problem A big question mark for the future is the source of highly purified silicon for solar cells. Fifty percent of the cost of a module is due to the cost of processed silicon wafers. The PV industry has in the past used reject material from the semiconductor industry that was available at low cost.
In 1959, Hoffman electronics succeed in creating solar cells that were 10% efficient. Solar cell technology gradually became more efficient and by 1970s, terrestrial use of solar panels became feasible. The cost of the solar cell modules decreased significantly over the next years and their use become more widespread.
In 1994, the National Renewable Energy Laboratory developed a new solar cell from gallium indium phosphide and gallium arsenide that exceeded 30% conversion efficiency. By the end of the century, the laboratory created thin-film solar cells that converted 32% of the sunlight it collected into usable energy.

High efficiency in perovskite solar cells is achieved by using a molecular hybrid of a self-assembled monolayer with nitrilotribenzoic acid.
1913 - William Coblentz receives US1077219, "Solar cell." 1914 - Sven Ason Berglund patents "methods of increasing the capacity of photosensitive cells." 1916 - Robert Millikan conducts experiments and proves the photoelectric effect. 1918 - Jan Czochralski produces a method to grow single crystals of metal.
The irradiance spectrum is an important consideration in designing solar cells, as solar cells respond differently to photons of different energy. The spectrum of sunlight changes continually as a function of time of the day, weather, and location. Solar cells are exposed to different spectra and hence need to operate under a variety of irradiances.
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

After Willoughby Smith discovered the photoconductivity of selenium (Se) in 1873, Charles Fritts constructed the first solid-state solar cells in 1883 by sandwiching Se film between a metal foil and a thin gold (Au) layer () spite the low preliminary power conversion efficiency (PCE) of <1%, these early discoveries initiated the research of photovoltaic field and …

The most important material has been and still is silicon. It dominates the present world market, particularly in its crystalline form but amorphous silicon is also of importance. Crystalline silicon solar cells are still heavily dependent on the materials base of the semiconductor industry. This material still has a large potential for cost ...
