A Solar cell, or photo-voltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. And it is also, one of the few devices that have potential to fully replace our conventional energy generation devices to a completely new era of safe and free energy but despite having tremendous plus points, like everything has its own flaws. Solar cell also comes with a heavy drawback i.e. it efficiency is quite low.

A New Solar Efficiency 

But Now researchers at the Australian National university (ANU) just hit a new record in the development of a low-cost solar cell that could truly change the way we generate solar electricity.

Previously this kind of efficiency have only been achieved using the high-cost materials normally used in satellites but due to this new development ” We are now a step closer to a low-cost alternative”, which could lead to a massive change in a way we use solar energy.

The ANU researchers have achieved this record by using a low-cost semi-transparent perovskite solar cells. Perovskite is a calcium titanium oxide mineral composed of calcium titanate (CaTiO3). It’s having a lattice-like structure that can help harvest light. They have successfully achieved 26 percent efficiency by mechanically combining perovskite with silicon cells.

The team, consist of Professor Kylie Catchpole and Ph.D. student The Duong. These folks able to achieved 26 percent efficiency in converting sunlight into energy using perovskite solar cells.

Professor Catchpole said while it was thermodynamically impossible to reach 100 percent solar cell efficiency, the researchers was aiming to increase efficiency to 30 percent and beyond.

While Researchers is trying to achieve this massive breakthrough in the field energy, it is not that far we’ll able to use high efficient low-cost solar cells.
