silicon photocell directly converts light energy into electrical energy is a kind of semiconductor devices. Its structure is simple, the core part is a large area of p-n junction ( Figure 9) 。 You can make a simple experiment, put a transparent glass shell of point-contact diode and a microampere meter into closed loops, when the diode tube core ( P-n junction) By light, you'll see whose hands deflect microamps table, showing in the loop current, this phenomenon is called light born v effect.

p-n junction area of the silicon photocell than two big p-n junction diode solar street lamps, so the electromotive force and the current caused by light is much greater. For example, the model of 2 cr silicon photocell under the incident light intensity of 100 mw/cm2, open circuit voltage ( With high internal resistance of the dc millivoltmeter measurement) For 450 ~ 600 mv, short circuit current for 16 ~ 30 ma, conversion efficiency is 6% ~ 12%. 【 The above content of the solar street light for you publish 】
