Contents
Big picture
| Time period | Development summary | More details |
|---|---|---|
| 1970s | As oil prices rise, demand for solar power increases, and research drives costs down.[1] |
Full timeline
| Year | Event type | Details | Location |
|---|---|---|---|
| 7th century BC | "In theory, solar energy was used by humans as early as 7th century B.C. when history tells us that humans used sunlight to light fires with magnifying glass materials. "[2] | ||
| 3rd century BC | "Later, in 3rd century B.C., the Greeks and Romans were known to harness solar power with mirrors to light torches for religious ceremonies. These mirrors became a normalized tool referred to as “burning mirrors.”"[2] | ||
| 20 AD | "The Chinese civilization documents the use of mirrors for the same purpose later in 20 A.D."[2] | China | |
| Late 1700s – 1800s | Researchers and scientists have success using sunlight to power ovens for long voyages. They also harness the power of the sun to produce solar-powered steam boats.[2] | ||
| 1839 | French physicist Edmond Becquerel first discovers the photovoltaic effect. This process occurs when light is absorbed by a material and creates electrical voltage. Most modern solar cells use silicon crystals to attain this effect.[1][3] | France | |
| 1873 | English electrical engineer Willoughby Smith discovers that selenium has photoconductive potential.[2][1] | United Kingdom | |
| 1876 | "William Grylls Adams’ and Richard Evans Day’s 1876 discovery that selenium creates electricity when exposed to sunlight."[2] | ||
| 1877 | American scientists William Adams and Richard Day publish The action of light on selenium.[4] | United States | |
| 1883 | American inventor Charles Fritts produces the first solar cells made from selenium wafers.[2] Fritts coats selenium with a thin layer of gold. This cell achieves an energy conversion rate of 1–2% (most modern solar cells work at an efficiency of 15–20%).[1] | United States | |
| 1887 | German physicist Heinrich Hertz first observes the photoelectric effect, where light is used to free electrons from a solid surface (usually metal) to create power. Hertz finds this process produces more power when exposed to ultraviolet light, rather than more intense visible light. Albert Einstein later receives the Nobel Prize for further explaining the effect. Modern-day solar cells rely on the photoelectric effect to convert sunlight into power.[1] | Germany | |
| 1888 | American chemist Edward Weston receives the first US Patent for solar cell.[4] | United States | |
| 1888 – 1891 | Russian physicist Aleksandr Stoletov develops the first solar cell using the outer photoelectric effect.[4] | ||
| 1902 | German physicist Philipp Lenard observes that the energy of individual emitted electrons increases with the frequency (which is related to the colour) of the light.[5] | Germany | |
| 1904 | German physicist Wilhelm Hallwachs develops a semiconductor-junction solar cell.[4] | Germany | |
| 1905 | Albert Einstein publishes his theory of “photoelectric effect”.[4] | ||
