Which two statements correctly describe the role of a semiconductor in a solar cell? A. When the semiconductors become charged, current flows from the positive one to the negative one.

B. When photons are absorbed, electrons from the semiconductor are freed because of the photoelectric effect.

C. The electrons frees from the semiconductor by light exit the cell and never return.

D. When the semiconductors become charged, current flows from the negative one to the positive one. ​

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
