Abstract

В статье основное внимание уделено гетероструктурным кремниевым (англ. SHJ -Silicon Hetero-Junction) солнечным элементам, которые, в отличие от стандартных кремниевых солнечных ячеек (как PERC, TOPCon и IBC), где p-n-переход формируется с помощью термической диффузии, базируются на низкотемпературных (< 250 °C) методах изготовления, обладают максимальным КПД (> 26%) и двусторонностью (> 90%), а также низким температурным коэффициентом (< 0.3%/°C). Все эти преимущества делают SHJ-солнечные ячейки очень привлекательными для наземной фотоэлектрической промышленности. Использование низкотемпературных процессов при изготовлении SHJ-ячеек приводит к возможности использования более тонких (< 140 мкм) кремниевых пластин при их массовом производстве и особенностям сборки солнечных модулей на их основе. Статья продолжает тему второго номера журнала,посвященного фотовольтаике.Авторы выражают благодарность многочисленным коллегам из ФТИ им. А.Ф. Иоффе РАН, ООО “НТЦ ТПТ” и ГК “Хевел”, без участия которых не могла быть решена задача создания отечественной наземной солнечной энергетики как отрасли.
