Short-Circuit Current

In the dark the basic solar cell structure with the donor component, acceptor component, anode and cathode is a diode. Electrons and holes are injected in a certain way based on whether a forward bias or a reverse bias is to be achieved. In a reverse bias, where the electrons go from the anode to the cathode, there will hardly be any current. In order for electrons to go from the anode to the cathode, the electrons must jump to the LUMO of the donor component. This will be very high in energy. On the other hand, in a forward bias where the electrons go from the cathode to the anode, there will be an injection barrier. Only when the injection barrier is overcome can your current start flowing.

Open-Circuit Voltage

The open-circuit voltage, V OC , is the maximum voltage available from a solar cell, and this occurs at zero current. The open-circuit voltage corresponds to the amount of forward bias on the solar cell due to the bias of the solar cell junction with the light-generated current. The open-circuit voltage is shown on the IV curve below. An equation for V oc is found by setting the net current equal to zero in the solar cell equation to give:. The effect of temperature is complicated and varies with cell technology.

Series and parallel connection of solar cells - open-circuit voltage and short-circuit current

Коридор, выложенный кафельными плитками, довольно круто спускался вниз, и Сьюзан держалась за перила, стараясь не отставать. Воздух в помещении становился все прохладнее. Чем глубже под землю уходил коридор, тем уже он становился.

Вполне вероятно, он решит поскорее вернуться в Канаду. Или надумает продать кольцо. Беккер не мог ждать. Он решительно поднял трубку, снова набрал номер и прислонился к стене.

Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250. Юбка девушки высоко задралась от ветра, но она не обращала на это ни малейшего внимания. Беккер рванулся к. Неужели все это происходит со мной? - подумал.  - Я же терпеть не могу мотоциклы.

В трубке раздались длинные гудки.

 Ein Vorschlag? - У немца перехватило дыхание.  - Предложение. - Да. Я могу прямо сейчас отвести вас в участок… - Беккер выразительно замолчал и прищелкнул пальцами.

 Господи Иисусе! - воскликнул водитель.  - С вами все в порядке. Мы уж думали, вы все погибли.
