The Structure and Composition of Photovoltaic Cells
Solar technology is really popular now because it can give us clean, renewable energy. Photovoltaic cell components are what make solar panels work. The most important part of these cells is the P-N junction. This junction is where p-type and n-type silicon come together. It makes an electric field that helps separate electrons from holes.
The electrical current made by solar cells is taken out through metal contacts. These contacts are on both the top and bottom of the cell. They are designed to collect and move the current outside the cell. Solar cells also have an anti-reflective coating. This coating cuts down on light lost by reflection. That way, more photons are absorbed, and the cell works better.
Here’s a table that shows different solar technologies and how they compare:
| Material | Average Efficiency | Cost (INR per W) | Notable Feature |
|---|---|---|---|
| Crystalline Silicon | 20.8% (PERC Cells) | ₹71.15 (Utility Scale, US 2020) | Durability >25 years |
| CdTe (Cadmium Telluride) | 10-15% | ₹74.77 (Commercial, China 2013) | Cd-free Manufacturing |
| CIGS (Copper Indium Gallium Selenide) | Up to 23.35% | Varies | High Lab Efficiencies |
| Perovskite | >25% | Not commercially standardized | Rapid Efficiency Improvements |
| Quantum Dot | Not highly efficient | Not commercially standardized | Challenges in Electrical Connections |
| Multijunction Cells | >45% | Not commercially standardized | Used in Space Exploration |
