Solar cell (image 2 of 3). Computer illustration of a solar cell charging in sunlight. Solar cells convert sunlight into electricity. This cell consists of 2 layers of silicon (Si,upper & lower left). The top layer also contains phosphorous (P) atoms. Atoms are seen as purple spheres. P normally holds 5 outer electrons (e-,blue),while Si holds 4. Sunlight on the top layer releases e- whose places around the P atom are taken by e- from the bottom layer. The e- build-up in the top layer can be discharged as an electric current. For the solar cell's structure & for it discharg- ing see images T155/108 and T155/110 respectively | |
