Amorphous Silicon Solar Panels Efficiency

Some would say amorphous panels are the most efficient solar technology available to the public today.

Amorphous silicon solar panels efficiency.

Four 25 watt solar panels give you plenty of clean quiet energy. While crystalline silicon achieves a yield of about 18 percent amorphous solar cells yield remains at around 7 percent. This has led the industry to develop double and even triple layer devices that contain cells stacked one on top of the other. Solar cell energy conversion efficiencies for commercially available multicrystalline si solar cells are around 14 19.

Due to complicated thermodynamics and the degradation of amorphous silicon among other factors amorphous solar cells are less than half as efficient as mono or poly crystalline solar panels. In most conditions in australia we strongly recommend poly monocrystalline panels. Amorphous silicon a si is the non crystalline form of silicon used for solar cells and thin film transistors in lcds. But through the manufacturing process of stacking several layers the efficiency of a si thin film solar panels have higher efficiency rates around 6 8 percent.

Amorphous silicon solar cells for maximum output in both bright and cloudy conditions. Amorphous solar panels offer around a 7 efficiency rate while mono and poly crystalline panels have efficiency ratings of anywhere from 14 to 20. The only exceptions being far north queensland and the northern territory where amorphous thin film may have some performance advantages during the hottest times of the year and given the amount of solar radiation in those areas a separate issue to heat. Amorphous is inherently less efficient than crystalline only being around 7 10 efficient at light conversion compared to a crystalline panel of the same size which has typically between 12 15 efficiency.

Solar cells manufactured with amorphous silicon have been typically less efficient and geared more toward small scale applications. Solar cell efficiencies vary from 6 for amorphous silicon based solar cells to 44 0 with multiple junction production cells and 44 4 with multiple dies assembled into a hybrid package. Yes they do require twice as much surface area to produce the same amount of energy but they produce that energy in a wider range of conditions and at a fraction of the weight. The amorphous solar cells offer efficient output in both bright and cloudy conditions.
