Q:Solar water heater plate can be directly converted into electrical energy?
Solar panels: solar panels are the core of the solar power system and the highest value part of the solar power generation system, which transforms the sun's radiant power into electricity or stores it in a battery or drives the load The quality and cost of solar panels will directly determine the quality and cost of the entire system;
Q:Why and what is the low efficiency solar cell?
The technical problems will cause the low efficienct of the solar cells, including solar and thermal energy, solar cells are now either absorb light energy, or absorb heat, there is little light and heat absorbed together.
Q:Doping and Diffusion Principle in Solar Cell Processing
The doping of semiconductors mainly relies on the principle of ion diffusion from high concentrations like low concentrations.
Q:Which brand of the solar cells is sold with the lower price on the market? Which brand is more practical for the countryside?
SMI is a professional solar cell provider in the current market, I am sure they can provide the solar cells with low price as you expected.
Q:How to generate solar cells, the principle of PN junction
Salt, such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenium and other multi-compound materials for the battery; 3, functional polymer materials prepared by the large solar cells; 4, nano-crystal solar cells.
Q:Do you believe you can make a solar cell by using kitchenware?
Really? Can you show me how?
Q:Anybody ever heard of solar roll flexible solar panel?
The flexible solar cells is more convenient to take with you, and also easy to charge as long as you do know how to use it properly.
Q:My solar cells are broken, can I just buy one and replace it?
You need to hire a professional to fix that for you.
Q:What are the advantages and disadvantages of solar panels and diodes?
If it is parallel in the positive and negative, then the protective effect, the diode is connected to the negative power supply, the diode negative connected to the positive power supply.
Q:What is the most commonly used material for solar cells?
Because of the commercialization of solar cells. The variety of solar cells includes monocrystalline silicon solar battery, poly silicon solar cell, non crystalline silicon solar battery, there are also,cadmium, copper indium, etc.
