Solar power is big news, but there's a problem with some types of solar cells. They just aren't very good at turning sunlight into energy. This is especially true for inorganic perovskite solar cells. These cells have a narrow bandgap, which makes them less efficient. But there's a new trick to make them work better. It involves a special chemical called guanidinoace...
Flexible solar cells have seen a lot of progress lately. They are getting better at turning sunlight into energy and staying tough. One big reason for this is the use of a special material called polyethylene naphthalate. This stuff is like the backbone of these solar cells, making them bendable and strong. Now, let's talk about something called 2D organic surface t...
The world of solar energy is always buzzing with new ideas. One of the latest focuses on tin-based perovskite solar cells. These cells have a special material called PSS. It's great at moving positive charges, but it has a big flaw. The acids in PSS react badly with the ITO electrode. This reaction can mess up the whole system. To fix this problem, researchers tried...
Tin-based perovskite solar cells (Sn-PSCs) have a problem. The material used to help transport charges, PEDOT:PSS, isn't doing a great job. It's not stable, and it doesn't work well with the tin perovskite. This is because of some issues with how they interact at the molecular level. But there's a clever solution on the horizon. A special molecule, called 2PADCB, is ...
Picture this: tiny gaps in a material that were once seen as a major issue. These are hydrogen vacancies in metal-halide perovskites, which are used to make solar cells. For a long time, scientists believed these vacancies caused a lot of energy loss as heat, instead of converting it into electricity. They called this nonradiative recombination. But guess wh...
Solar cells are getting a green makeover. Researchers are ditching toxic chemicals in favor of safer, eco-friendly solvents. This shift isn't just about being kind to the planet; it's also about making solar cells work better. Imagine trying to build a sandcastle with wet, sticky sand. It's a mess, right? That's similar to what happens when toxic solvents like chlor...
Solar power is a hot topic in the world today. Scientists are always trying to make solar cells more efficient. Recently, two types of polymers, P3CT and P3HT, have been used as hole transport layers (HTLs) in perovskite solar cells. These materials are important because they help collect the energy from sunlight. The structure and behavior of these polymers are cru...
Imagine a tiny helper molecule that melts, flows, and then seals itself around perovskite solar cells. This clever "stepwise melting-polymerizing molecule" (SMPM) is like a tiny shield, protecting the cells from damaging humidity. During the cell-making process, SMPM goes through three stages: it melts from solid to liquid, spreads out to cover grain boundaries, and ...
