SiC Schottky diodes stop the batteries from discharging from the photo voltaic cells at night and stop higher-undertaking solar cells from discharging by way of lower-general performance solar cells. With AlGaN and AlGaInN, even shorter wavelengths are achievable. Close to-UV emitters at wavelengths around 360–395 nm are currently low cost https://funny-lists.com/story14131936/what-does-bare-die-sic-schottky-diodes-mean
