АНАЛИТИЧЕСКАЯ ФОРМА ВОЛЬТАМПЕРНОЙ ХАРАКТЕРИСТИКИ СОЛНЕЧНЫХ ПРЕОБРАЗОВАТЕЛЕЙ НА ОСНОВЕ W-ФУНКЦИИ ЛАМБЕРТА ДЛЯ ЕЕ ПРЯМОЙ И ОБРАТНОЙ ВЕТВИ

ANALYTICAL EXPRESSION FOR THE CURRENT-VOLTAGE CHARACTERISTIC OF PV CELLS BASED ON LAMBERT W-FUNCTION FOR ITS FORWARD AND REVERSE BRANCHES

АНАЛИТИЧЕСКАЯ ФОРМА ВОЛЬТАМПЕРНОЙ ХАРАКТЕРИСТИКИ СОЛНЕЧНЫХ ПРЕОБРАЗОВАТЕЛЕЙ НА ОСНОВЕ W-ФУНКЦИИ ЛАМБЕРТА ДЛЯ ЕЕ ПРЯМОЙ И ОБРАТНОЙ ВЕТВИ

Abstract

Предложена двухдиодная модель фотоэлектронного солнечного преобразователя, позволяющая представить в единой аналитической форме полную вольтамперную характеристику преобразователя (ВАХ) с учетом прямой и обратной ветви на основе W-функции Ламберта. Модель позволяет достаточно детально изучать влияние на обратную ветвь ВАХ в отрицательной области напряжений явлений, связанных с ударным механизмом размножения носителей заряда в области p-n перехода. Показано хорошее совпадение между экспериментальными и модельными кривыми для кремниевых солнечных элементов. С практической точки зрения ВАХ, записанная в виде единого аналитического уравнения с W-функциями Ламберта, позволяет анализировать поведение последовательного соединения солнечных элементов, модулей и панелей, находящихся при неравномерной их освещенности, имеющее место на действующих солнечных электростанциях.

Two-diode model of PV cell is proposed, which makes it possible to present in a unified analytical form the full current-voltage characteristic considering both forward and reverse branches based on the Lambert W-function. The model allows a fairly detailed study the effect of avalanche breakdown mechanism in the p–n junction on the reverse branch of the I–V characteristic. Good fitting has been show between the experimental and modeled I-V curves for silicon PV cells. From a practical point of view, a unified analytical form of the full current-voltage characteristic with Lambert W-functions is allows to analyze behavior of the series connection of PV cells and modules under uneven illumination in running solar power plants.
