Повышение эффективности кремниевых солнечных элементов легированием никелем

Abstract

It is shown that in the near-surface region of the solar cells SCs the concentration of nickel atoms is higher than in the bulk by 2ndash;3 orders of magnitude, therefore, the gettering rate in the near-surface region is higher. Optimal modes of gettering by nickel clusters i.e., nickel diffusion ndash; Т = 800ndash;850 deg;С, additional thermal annealing ndash; Т = 750ndash;800 deg;С and the structure of a silicon SC were experimentally determined, which makes it possible to increase the efficiency of silicon SCs by 25ndash;30% relative to the control. The physical mechanisms of the influence of the processes of diffusion of impurity nickel atoms and additional thermal annealing on the state of nickel atoms in the near-surface region and the SCs base and, accordingly, on the parameters of the SC are revealed. Physical models of the structure of a cluster of nickel atoms in silicon and the process of fast diffusing impurities gettering by clusters of nickel atoms are created. The binding energy of fast dissusing impurities atoms with a nickel cluster is estimated to be ~ 1.39 eV. The calculation shows that doping with nickel can increase the lifetime of minority charge carriers by 2ndash;4 times, and the collection coefficient by 1.4ndash;2 times. The experiment showed an increase in the minority charge carriers lifetime up to 2 times and an increase in efficiency by 25ndash;30%.

Показано, что в приповерхностной области солнечных элементов СЭ концентрация атомов никеля выше, чем в объеме, на 2ndash;3 порядка, поэтому скорость геттерирования в данной области больше. Экспериментально определены оптимальные режимы геттерирования класте-рами никеля то есть диффузии никеля ndash; Т = 800ndash;850 deg;С, дополнительного термического отжига ndash; Т = 750ndash;800 deg;С и структура кремниевого СЭ, позволяющая повысить его эффектив-ность на 25ndash;30% относительно контрольной. Выявлены физические механизмы влияния процессов диффузии примесных атомов никеля и дополнительного термического отжига на состояние атомов никеля в приповерхностной области и базе СЭ и соответственно на параметры СЭ. Созданы физические модели структуры кластера атомов никеля в кремнии и процесса геттерирования быстродиффундирующих примесей кластерами атомов никеля. Оценена энергия связи ~ 1,39 эВ атомов быстродиффундирующих примесей с кластером никеля. Расчет показывает, что легирование никелем может увеличить время жизни неосновных носителей заряда в 2ndash;4 раза, а коэффициент собирания ndash; в 1,4ndash;2 раза. Эксперимен-тально продемонстрировано увеличение времени жизни неосновных носителей заряда до 2 раз и рост эффективности СЭ на 25ndash;30%.
