The timeline of solar cells begins in the 19th century when it is observed that the presence of sunlight is capable of generating usable electrical energy. Solar cells have gone on to be used in many applications. They have historically been used in situations where electrical power from the grid was unavailable. == 1800s == * 1839 - Alexandre Edmond Becquerel observes the photovoltaic effect via an electrode in a conductive solution exposed to light. * 1873 - Willoughby Smith finds that selenium shows photoconductivity. * 1877 - W.G. Adams and R.E. Day observed the photovoltaic effect in solidified selenium, and published a paper on the selenium cell. 'The action of light on selenium,' in "Proceedings of the Royal Society, A25, 113. * 1878 - Augustin Mouchot displays a solar power generator at the Universal Exhibition in Paris. * 1883 - Charles Fritts develops a solar cell using selenium on a thin layer of gold to form a device giving less than 1% efficiency. * 1887 - Heinrich Hertz investigates ultraviolet light photoconductivity and discovers the photoelectric effect * 1887 - James Moser reports dye sensitised photoelectrochemical cell. * 1888 - Edward Weston receives patent US389124, "''Solar cell''," and US389125, "''Solar cell''." * 1888-91 - Aleksandr Stoletov creates the first solar cell based on the outer photoelectric effect * 1894 - Melvin Severy receives patent US527377, "''Solar cell''," and US527379, "''Solar cell''." * 1897 - Harry Reagan receives patent US588177, "''Solar cell''." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Timeline of solar cells」の詳細全文を読む スポンサード リンク
