Why and what is the low efficiency solar cell?
The first thing we need to think about when the solar cells is becoming low efficient is to measured the reflectivity of the solar cells.
I do know when the energy is absorbed by the solar cell, there will be loss in the conversion, that is one of the reason that the solar cell becomes low efficient.
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.
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
The low efficient solar cells is usually considered to be the solar cells which can not provide as much power supply as the other conventional solar cell. Reaons varies based on different materials.
