2. Testning av fotovoltaik (solceller)<\/h3>\n\n\n\n
I h\u00f6geffektiva solcellsprocesser som PERC och TOPCon anv\u00e4nds kvartsr\u00f6r f\u00f6r deponering av passiveringsskikt (t.ex. SiNx eller Al\u2082O\u2083) eller h\u00f6gtemperaturbr\u00e4nning.
B\u00e4rarlivsl\u00e4ngden p\u00e5verkar direkt cellens omvandlingseffektivitet. Om kvartsr\u00f6ret tillf\u00f6r f\u00f6roreningar kommer rekombinationshastigheten p\u00e5 skivans yta att \u00f6ka.

\n\n\n\n3. Materialforskning (t.ex. halvledare med brett bandgap)<\/h3>\n\n\n\n
H\u00f6gtemperaturprocesser (>1500\u00b0C) f\u00f6r kiselkarbid- (SiC) eller galliumnitrid- (GaN) komponenter kr\u00e4ver ultrarena kvartsr\u00f6r. F\u00f6roreningar kan \u00f6ka gr\u00e4nssnittets tillst\u00e5ndst\u00e4thet, vilket leder till minskad b\u00e4rarlivsl\u00e4ngd.
Forskningen fokuserar ofta p\u00e5 de elektriska egenskaperna hos epitaxiella skikt eller oxidskikt.<\/p>\n\n\n\n
\n\n\n\n4. Andra relaterade tester<\/h3>\n\n\n\n
B\u00e4rarens livsl\u00e4ngd p\u00e5verkar svarshastigheten. Om kvartsr\u00f6r kontaminerar k\u00e4nsliga material (t.ex. InGaAs) kan enhetens prestanda f\u00f6rs\u00e4mras.<\/p>\n\n\n\n
Vissa kunder kanske helt enkelt anv\u00e4nder kvartsr\u00f6r som reaktionsk\u00e4rl f\u00f6r att testa b\u00e4rardynamiken hos nya material (t.ex. perovskiter).<\/p>\n\n\n\n

Denna parameter \u00e4r kritisk inom halvledar- och solcellsomr\u00e5det, medan typiska industriella eller kemiska experiment i allm\u00e4nhet inte m\u00e4ter den specifikt.<\/p>\n\n\n\n
Allm\u00e4nna kemiska experiment har relativt l\u00e5ga renhetskrav f\u00f6r kvartsr\u00f6r, medan halvledar- och fotovoltaikprocesser \u00e4r extremt k\u00e4nsliga f\u00f6r kontaminering.<\/p>","protected":false},"excerpt":{"rendered":"
