Perovskite solar cell: interface makes the difference

Perovskite-based solar cells are the fastest-advancing solar technology to date. Since they were first used in 2009, perovskite solar cells have achieved high efficiencies (over 22% under standard solar irradiation) at low production costs. Although most of the perovskite components are optimized, there’s still room for improvement. Especially in reference to the Hole Transport Materials […]

Do solar panels and home batteries save energy?

The energy produced over the lifetime of typical rooftop solar panels more than makes up for the energy it takes to make, mount and then eventually recycle them. But adding a home battery usually lowers those dividends, according to new research from Stanford University. Previous studies estimated the energy output to be about nine times […]

Stability of solar cells in near space tested

Chinese researchers have found that solar cells can retain most of their power conversion efficiency in near space, providing perspectives on the cells’ future application in space. Perovskite solar cells (PSCs) are known for their potential of achieving higher efficiency and low production costs compared to traditional silicon solar cells. These cells also have great […]

Scientists develops solar-powered device that creates water from thin air

In a “breakthrough”, scientists have developed a novel solar-powered harvesting system that absorbs moisture from the air and converts it into clean, usable water. The technology, described in the journal Advanced Materials, could be used in disaster situations, water crises or poverty-stricken areas and developing countries. It relies on hydrogels, gel-polymer hybrid materials designed to […]

Scientists develops simple, inexpensive frame that can boost solar cell efficiency

Scientists have designed a metal frame that increases the amount of sunlight captured by a solar cell, enhancing its energy production by almost one-third. The simple, inexpensive and ingenious method could increase solar energy captured for people in developing countries, as well as remote regions that are off the grid, researchers said. “In Uganda, between […]
