Perovskite Solar Cell

Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into light. The technique opens the door to engineering materials tailored for use in next-generation printed LEDs and lasers—and holds promise for engineering other materials…

CSIRO achieves groundbreaking efficiency with fully roll-to-roll printed solar cells, promising lightweight, flexible, and cost-effective clean energy solutions for diverse applications.

Until recently, chalcopyrite-based solar cells have achieved a maximum energy conversion efficiency of 23.35%, as reported in 2019 by Solar Frontier, a former Solar Energy company based in Japan. Further boosting this efficiency, however, has so far proved challenging.

The two-layer panels still suffer from rapid decay of performance, though.

Physicists in the U.S. jumped a major hurdle standing in the way of the commercialization of solar cells created with halide perovskites as a lower-cost, higher-efficiency replacement for silicon when generating electricity from the sun.

A new approach to manufacturing perovskite solar cells has addressed previous problems and yielded devices with high efficiency and excellent stability, researchers at the National Renewable Energy Laboratory (NREL) report in the new issue of the journal Science.

Incorporated inside and outside buildings—even in windows—new panels could help expand green energy potential

Metal halide perovskites (ABX3) have emerged as promising candidates for various optoelectronic applications due to their excellent optoelectronic properties and low-cost fabrication. At present, the light-absorbing layer of the highest-efficiency single-junction perovskite solar cells (PSCs) is almost all based on FAPbI3 perovskite, achieving power conversion efficiency (PCE) that is comparable to commercial…

A team of researchers has found that the tiny defects which limit the efficiency of perovskites -- cheaper alternative materials for solar cells -- are also responsible for structural changes in the material that lead to degradation.

Here's how it acquires power even at night.

A new study has unlocked nanoscale secrets for designing next-generation solar cells. The work will help researchers tune surface properties of perovskites, a promising alternative and supplement to silicon, for more efficient photovoltaics.

Solar panels are mostly made of silicon, which derives from sand. Here's how that abundant substance is transformed into something that generates electricity.

Companies say perovskite tandem solar cells are only a few years from bringing record efficiencies to a solar project near you.

Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique developed by a team of international scientists could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing…

The Biden administration is announcing more than $80 million in funding as part of a push to make more solar panels in the U.S. and make solar energy available in more communities.

The Biden administration announced more than $80 million in funding Thursday in a push to produce more solar panels in the U.S., make solar energy available to more people, and pursue superior alternatives to the ubiquitous sparkly panels made with silicon. The Department of Energy announced the investments in the

Electrostatic doping has been widely used in low-dimensional materials, including carbon nanotube (CNT) and two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs). Unlike conventional lattice doping with impurity atoms, it is challenging to achieve doping in nanoscale materials due to the limited physical space. The electrostatic doping opens an effective pathway to tune the…
