变压器的主绝缘包括高压与低压绕组之间、不同相之间以及对地绝缘和引线等对地或对其他绕组的绝缘。主绝缘需确保这些部位的绝缘在工频1min试验电压和冲击试验电压下不发生击穿,在长期最大工作电压下不发生有害的局部放电。
A wafer-based solar cell is a unique type of non-mechanical semiconductor that uses a p-n junction to produce the photovoltaic effect — transforming photons from sunlight into direct current electricity. Semiconductors are an essential component of almost all modern electronic devices and appliances ...
Since the first report on a long-term durable solid-state perovskite solar cell with a PCE of 9.7% in 2012, a PCE as high as 19.3% was demonstrated in 2014, and a certified PCE of 17.9% was shown in 2014. Such a high photovoltaic performance is attributed to optically high absorption ...

“You can’t have a solar cell that decomposes quickly when it’s meant to last 20 years in the field,” Jamie added.“This is a missing link in the whole of techniques we have to throw at that problem.”1. What is the shortcoming of perovskite solar cells? A.It’s very expensive...
What Does Dye-Sensitized Solar Cell Mean? Dye-sensitized solar cells (DSSCs) are a special kind of a low-cost solar (photovoltaic) cell that efficiently converts visible light into electrical energy. Invented in 1991 by Professor Michael Graetzel and Dr. Brian O’Regan, it is given the ...
Drying anode material: Spreader anode material is dried to form an anode electrode. Preparation of packaged devices: The prepared solar cells are packaged in Glass or polymer packaged devices to form a complete solar cell module. Particularly important is that the perovskite-specific Automatic Film ...
There is a need for a potential alternative to the current market-dominating HTM due to its high cost of production, dopant requirements, moisture sensitivity, and low stability. Among several proposed HTMs, molecules derived from thiophene exhibit unique behaviour, such as the interaction with ...
