Laten we nu kristallen als voorbeeld nemen om het proces van fotovolta\u00efsche energieopwekking te introduceren. P-type kristallijn silicium kan worden gedoteerd met fosfor om N-type silicium te verkrijgen, waardoor een PN-overgang ontstaat. Wanneer er licht op het oppervlak van een zonnecel schijnt, worden sommige fotonen geabsorbeerd door het siliciummateriaal. De energie van de fotonen wordt overgedragen aan de siliciumatomen, waardoor elektronen migreren en vrije elektronen worden. Deze elektronen verzamelen zich aan beide zijden van de PN-overgang en vormen een potentiaalverschil. Wanneer het circuit is verbonden met de buitenwereld, zal er onder invloed van spanning een stroom door het externe circuit vloeien, waardoor een bepaald uitgangsvermogen wordt gegenereerd. De essentie van dit proces is het proces waarbij fotonenergie wordt omgezet in elektrische energie.<\/p>\n<p><a href=\"https:\/\/www.ray-tron.com\/nl\/\" data-internallinksmanager029f6b8e52c=\"14\"
