A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to po...
Using an innovative device that can energise old solar cells with multiple times the intensity of sunlight, scientists from EtaVolt, a spin-off from NTU Singapore can rejuvenate old solar panels qu...
What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs. In order to withstand the outdoors for many years, cells are sandwiched between protective materials in a combination of glass and/or plastics. ...
There are breakthroughs in solar technology announced nearly every day from laboratories around the world. Here's a rundown of solar technologies that will actually have an impact in the near future.

Princeton Engineering researchers have developed the first perovskite solar cell with a 30-year lifespan. The new device is the first of its kind to rival the performance of silicon-based solar cel...
TOPCon solar cell technology is one of the latest trends in the solar industry, developed as an upgraded and more advanced version of the PERC/PERT technology. One of the main advantages of TOPCon solar cells is that the structure is only slightly different from PERC/PERT solar cells , meaning that manufacturers can use practically the same production line with a few improvements to produce TOPCon solar cells. The main setback of this new technology compared to PERC/PERT is that the TOPCon solar cells require a larger amount of silver (Ag) for ...
Silicon-based solar cells have a theoretical efficiency limit of around 30 per cent, but adding a perovskite layer enables new designs to harvest more energy
Solar panels are cooler than the night air, creating a temperature difference that can be exploited to produce electricity
