Solar energy: the perovskites break the record again!

At present, work is being carried out on several tracks to improve the efficiency of many different techniques for generating solar energy. The researchers have succeeded in the novel Perovskite silicon tandem solar cells to achieve an efficiency of almost 30, more precisely 29,15%. This is another record in the category.

Success in efficiency was achieved through the use of an experimental 1 cm x 1 cm plate. After three hundred hours of laboratory operation, the tandem cell has retained 95% of its original efficiency, which is considered a promising result. At the beginning of 2020 a new record was registered, but with the announcement of the result the publication of a scientific paper on this topic in "Science" was waited for.
Last year also saw further records in the conversion efficiency of solar energy. In April, a group of scientists from the American National Renewable Energy Laboratory (NREL) reported that the construction of their six-connector solar cell had achieved an efficiency of 47,1% with a concentration of sunlight. This record exceeds the previous result from a few years ago by one percent. Another design that did not use a concentration achieved an efficiency of 39,2%, which was also considered a record.
