20+ hour, 51+ min ago   (333+ words) Yunnan University team demonstrates underwater power supply for marine robots with durable perovskite modules A research team led by Professor Zhang Wenhua of the School of Materials and Energy at Yunnan University in China verified the performance of perovskite solar…...

1+ day, 13+ hour ago   (489+ words) Tin halide perovskites have long been the tantalizing alternative to lead-based perovskites in next-generation solar cells. They offer a narrower bandgap that is ideal for harvesting more of the solar spectrum, and they replace toxic lead with an environmentally friendlier…...

1+ day, 16+ hour ago   (698+ words) Perovskite solar cells have spent more than a decade rewriting the record books, but the most valuable real estate in these devices has always been the interface, the razor-thin boundary where the light-absorbing perovskite layer meets the contacts that siphon…...

3+ day, 9+ hour ago   (371+ words) Researchers at China’s Nanjing University have fabricated a perovskite-organic tandem solar cell featuring a bottom organic subcell that uses a low-bandgap (LBG) acceptor to enhance near-infrared (NIR) absorption while reducing voltage losses. The researchers said previous studies have used various…...

2+ day, 15+ hour ago   (726+ words) Perovskite solar cells have spent the past decade shattering one efficiency record after another, but the technology’s most ambitious configuration—stacking three perovskite absorbers on top of one another in a single monolithic device—has remained stubbornly out of reach....

4+ day, 3+ hour ago   (331+ words) One drawback of most solar cells made with efficiency-boosting perovskite is the presence of hazardous lead in the materials that turn sunlight into electricity. Next-generation solar cells made with the most promising, lead-free replacement — non-toxic tin perovskite — have had their…...

4+ day, 9+ hour ago   (323+ words) The researchers built the monolithic perovskite-silicon tandem solar cell with a crystalline silicon (c-Si) bottom cell and an inverted p-i-n perovskite top cell. The silicon subcell features intrinsic amorphous silicon (a-Si(i)) and doped nanocrystalline silicon oxide (nc-SiOₓ(n)) passivating contacts,…...

5+ day, 1+ hour ago   (235+ words) A new review provides an integrated perspective on two-dimensional (2D) and quasi-2D lead-free halide double perovskites (LFHDPs), an emerging class of materials for more sustainable optoelectronic technologies. The review connects crystal structure with optical and electronic properties and device performance, covering…...
