Creating the Silicon Wafers: Shaping the Future of Solar Energy
The solar panel fabrication process has improved a lot over the years. This has led to big growth in the photovoltaic industry. Especially, making silicon wafers has been key in this growth. Silicon is very important in crystalline silicon solar cells, holding a 90% market share. This shows its key role in making solar technology work well and efficiently.
The process starts with turning high-purity silicon ingots into silicon wafers. This is the foundation of solar cells. These ingots, sometimes over 800 kg for multi-crystalline types, are cut into 6 inches x 6 inches wafers. These are the standard sizes for cell making. Then, doping these wafers with boron creates p-type Si substrates. These are the most used type because they convert energy well and reliably.
Solar cells have become from less than 1% efficient in the 1950s to over 23% today. This big improvement is thanks to better manufacturing technologies. For instance, moving from Aluminum Back Surface Field (Al-BSF) cells to Passivated Emitter and Rear Cell (PERC) processes. These changes, although they need more tools, lead to about 21% efficiency. Some very advanced PERL cells even reach 24%. Many countries are investing in their production to be top players in the global market. They want a future where solar solutions are efficient and help lower carbon emissions.
Fenice Energy, with over twenty years in clean energy, has added these new methods to its facilities in India. The company is not just about making high-quality solar parts. It’s also about creating jobs and cutting CO2 emissions in production.
