Ndị ọkà mmụta sayensị anọwo na-anwale mkpụrụ ndụ anyanwụ nke perovskite. Perovskite bụ mineral na-adịghị ahụkebe n'elu ụwa, calcium titanate. Ebe ọ bụ na e mepụtara prototype mbụ nke cell cell perovskite na 2009, ngwaahịa ndị dị otú ahụ egosiwo mmụba ngwa ngwa na arụmọrụ: uru a ugbu a karịrị 25%.
Iji mee ka arụmọrụ dịkwuo elu, a na-atụ aro ka ịmepụta ihe dị n'elu nke oyi akwa na-ekpo ọkụ. Anyị na-ekwu maka usoro nke protrusions na grooves ọzọ: n'ihi nke a, ọkụ na-agbasasị nke ọma n'elu ihe ndị na-adịghị mma ma na-etinye uche nke ọma karị, nke na-eme ka o kwe omume ịbawanye arụmọrụ.
