Question:

Solar Panels heat absorption?

Do solar panels work with any type of heat or only sunlight? I have a bunch of little ideas floating around in my head and Id like to get them on paper but only if they really would work.Also does a concentrated amount of heat on one solar panel piece (quot;xor so) produce a higher or equal amount of electricity than a less concentration over a larger area?

Answer:

Solar photovoltaics require light, any kind of light. A torch would work, for example. The effect of concentration depends on the amount of light and the material you're shining it on. In CdTe, warmer temperatures and more intense light may lead to better performance. In silicon I think the opposite is true (I don't know though, I've only done research work with CdTe). It depends on properties of the semiconductor, like its band structure. To get an 'order of magnitude' estimate, you may assume a constant efficiency of solar cell so total amount of light (= area * intensity) largely determines the output in standard operating conditions.
solar panel just suit the sunshine.because it has big light intensity . it can make solar panel produce electric charger.
Last year here in the UK we had in my area snow most days quite heavy lays of it I noticed after clearing my solar cell panels in daylight conditions without any sun they were producing a fairly good voltage/amp ration, also as daft as it sounds in the middle of a January night with a good moon shin the snow refection produced a good electricity supply!. absolutely true.
Solar panels . Are you talking about solar cells or panels ? Solar panels can be either for hot water or electricity but i take it your talking about solar cells that make electricity . Heat has nothing to do with making electricity . In fact when they heat up they give out less so its good to keep them cool . With size they give out equal amounts of volts but less amp the larger the more amp you get. Solar cells work with white light that knock the electrons around that produce electricity . To much such as putting a magnifying glass on them will burn them up but will kick out twice the volt but only for a short amount of time before they burn up . If you can keep them cool with an intense light like that im not sure what they will do but to much heat will destroy them. Edit: Yep you got that right . As far as the desert to make up for the loss of volts because of the heat they just add a few more cells . Say there going for 2 volt it takes 24 cells because each gives you /2 volt but most use around 36 cells if not more . That would give you 8 volt then a regulator regulates the amount going into the battery . Most will put 3 volt into the battery to 4 volt . Freezing temps aren't going to do a thing to them as long as the sun hits them without snow covering them . I build mine with 40 cells getting 20 volt and a bit more on some . That way if its a cloudy day i still get over 3 volt and plenty of amps .
