photodiodes are basically reverse biased diodes with optical windows that allow like to shine on the PN junction. Like any diode, the leakage current (otherwise known as a photodiodes 'dark' current) increases exponentually with temperature in accordance to William Shockley's idea diode eqation. The other effect in a photo diode is the probability of a photon of a certain energy allowing an electron to cross the PN junction. This is known as the quantum efficiency of the photodiode. Because increasing temperatures increase the vibration of the silicon atoms, making them easier to be knocked loose by a photon. Thus the quantum efficiency of a photodiode will increase with tempature, as well as the thermally induced noise. photodiodes are basically reverse biased diodes with optical windows that allow like to shine on the PN junction.

The photodiode's voltage drop varies with the temperature and current flowing through it. The typical voltage drop (VBIAS - VREF) across the MAX4007 series is 0.8V, with a guaranteed maximum of 1.1V.

Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
1) Bi metallic strip ,which acts as overload protection switch in electrical appliances. 2) Thermocouples, which use heat and cold effect to generate electricity. 3) Thremo resistor which change their resistance with a change in temperature.
conductivity of semiconductors increases with increase in temperature as breakdown of covalent bonds take place in the semiconductor due to increase in temp but more & more increase in the temp may result in the breakdown or damage of the semiconductor which results in the decrease in conductivity of semiconductor
When Einstein discovered photoelectric effect!

One can purchase a photodiode from retail stores like Target, Walmart and many more. One can also purchase a photodiode from online websites like eBay or Amazon.
the function of a photodiode is produce some reverse current in the external resistor of circuit.
effect of temperature
since the mouse having photodiode installed in them are so fast in response and have less chances of damage.
A light-emitting diode (LED) emits light when an electric current passes through it. A photodiode, on the other hand, generates an electric current when exposed to light. In summary, an LED produces light, while a photodiode detects light.

Avalanche photodiode advantages and disadvantagesThe avalanche photodiode has a number of different characteristics to the normal p-n or p-i-n photodiodes, making them more suitable for use in some applications. In view of this it is worth summarising their advantages and disadvantages.. The main advantages of the avalanche photodiode include:Greater level of sensitivityThe disadvantages of the avalanche photodiode include:Much higher operating voltage may be required.Avalanche photodiode produces a much higher level of noise than a p-n photodiodeAvalanche process means that the output is not linear
yes, temperature does effect plastic if it gets to hot it can melt it.
