What else can I help you with?
Mention the different types of photoelectric cells?
there are three types ,they are photoconductive cell ,photoemissive cell and photovoltiac cell
What is photoconductive cameratube?
A photoconductive camera tube is a type of electron tube used in early television cameras. It works by converting light into electrical signals. When light falls on the photoconductive materials inside the tube, they change their electrical resistance, allowing the tube to capture and convert the light information into an electronic signal.
What are some selenium uses?
Some applications of selenium:- red glass fabrication- rubber vulcanization- manganese refinning by electrolysis- component of alloys- solar cells- photoconductive materials- inorganic dyes
What happens when selenium is exposed to light?
Selenium is photoconductive, meaning its electrical conductivity increases when exposed to light. This property is used in applications such as photocopiers and solar cells. However, prolonged exposure to bright light can degrade selenium's performance.
What are photo conductive polymers?
photoconductive polymers are materials that change their electrical conductivity when subject to light (infra red- visible - ultraviolet - gamma). They are mainly used in photocopiers and holography.
What has the author William George Williams written?
William George Williams has written: 'The hole mobility and photoconductive properties of rubrene'
What does a photoresistor do?
What does a photoresistor do ?Photoresistors (also often called phototransistorsor CdS photoconductive photocells; use 'photocell' for digikey) are simple resistors that altar resistancedepending on the amount of light place over them.
What has the author Eugene Paul Steinmetz written?
Eugene Paul Steinmetz has written: 'The minority carrier lifetimes in germanium and silicon semiconductors by the methods of photoconductive-decay' -- subject(s): Semiconductors
Is photocurrent proportional to the intensity of light?
Yes, photocurrent is typically proportional to the intensity of light. Higher intensity light generates more electrons in the photoconductive material, leading to a higher current.
WHAT IS A photo conductive?
I think It is a cell that absorbs light like in plants but I'm not 100%
What has the author J R Houck written?
J. R Houck has written: 'Long wavelength photoconductive detectors for airborne and orbital infrared astronomy' -- subject(s): Infrared astronomy, Photoconductivity
What are the chemical and physical properties of selenium?
Selenium is a nonmetal element with the atomic number 34. It is a brittle solid at room temperature with a metallic luster. It exhibits both photovoltaic and photoconductive properties, making it useful in solar cells and photocopying. Selenium is a semiconductor that can conduct electricity under certain conditions. Its chemical properties include forming compounds with both metallic and nonmetallic elements, and it is essential for various biological functions in trace amounts.
