Incorporating solar harvesting into the side of buildings could enhance energy sustainability

If builders could incorporate solar harvesting into the siding of a building, the amount of energy from the grid that a structure would need may significantly decrease. In research published recently in Renewable Energy, a team of researchers from Rensselaer Polytechnic Institute, led by Diana-Andra Borca-Tasciuc, a professor of mechanical, aerospace, and nuclear engineering, demonstrated the potential of wedge-shaped luminescent solar

Say farewell to silicon, and hello to calcium titanium oxide

When it comes to the future of solar energy cells, say farewell to silicon and hello to calcium titanium oxide — the compound mineral better known as perovskite. Cornell University engineers have found that photovoltaic wafers in solar panels with all-perovskite structures outperform photovoltaic cells made from state-of-the-art crystalline silicon, as well as perovskite-silicon tandem cells, which are stacked pancake-style

Scaled-up perovskite solar cells developed by NTU Singapore scientists achieve highest recorded power conversion

A team of researchers at the Nanyang Technological University, Singapore (NTU Singapore) has created a perovskite solar mini module that has recorded the highest power conversion efficiency of any perovskite-based device larger than 10 cm2. Perovskites are new materials that have emerged as promising alternatives to silicon in solar cell applications. The material offers power conversion efficiencies similar to silicon solar cells

Cooling mechanism to increase solar energy harvesting for self-powered outdoor sensors

Sensors placed in the environment spend long periods of time outdoors through all weather conditions, and they must continuously power themselves in order to collect data. Many, like photovoltaic cells, use the sun to produce electricity, but powering outdoor sensors at night is a challenge. An illustration of thermoelectric devices using a wavelength-selective emitter and a broadband emitter. The device
