Self-assembly construction of a homojunction of Sn–Pb …
All-perovskite tandem solar cells (PTSCs) demonstrate higher power conversion efficiency (PCE) and lower levelized cost of electricity than single-junction perovskite solar cells (PSCs). However, narrow bandgap (NBG) sub-cells with a Sn–Pb alloy cause severe p-type self-doping by surface oxidized Sn4+ to gen
Work function tuning of a weak adhesion homojunction for stable …
In this work, we reveal the existence of a built-in potential at the homojunction interface of the perovskite film near the electron-transporting SnO2 layer. Adjusting the energy-level alignment at this interface is found to play a critical role in mitigating ion migration, which eventually enhances photovoltaic performance and stability.

Here, we developed a one-step self-assembly strategy to construct a p/p − homojunction of Sn–Pb perovskite using the antioxidant 4 …
Homojunction
A homojunction is a semiconductor interface that occurs between layers of similar semiconductor material; [1] these materials have equal band gaps but typically have different doping. In most practical cases a homojunction occurs at the interface between an n-type ( donor doped) and p-type ( acceptor doped) semiconductor such as silicon, this is called …

What is Homojunction and Heterojunction Semiconductor?
Is homojunction different from p-n junction? Mostly, it occurs at the interface between an n-type (known as donor doped) and p-type (known as acceptor doped) semiconductor such as silicon. For example, n-type to n …
Integrating Energy Band Alignment and Oxygen Vacancies Engineering of TiO2 Anatase/Rutile Homojunction for Kinetics‐Enhanced Li–S Batteries ...
The inferior shuttle effect of intermediate lithium polysulfides and the sluggish kinetics of sulfur redox reaction are two serious puzzles for the application of lithium–sulfur batteries. Herein, energy band alignment is combined with oxygen vacancies engineering to obtain TiO2 anatase/rutile homojunction (A/R‐TiO2) with effective …
Phototransistors: What Are They & How Do They Work?
What is a Phototransistor? Phototransistors are semiconductor devices with either three terminals (emitter, base, and collector) or two terminals (emitter and collector) and have a light-sensitive base region. While all transistors are somewhat light-sensitive, phototransistors are specifically optimized for light detection. They are made …

What Is mAh, and How Does It Affect Batteries and Chargers?
If that battery can maintain a current output of one milliamp for 1 hour, you could call it a 1 mAh battery. A milliamp is a tiny amount of power, so this battery wouldn''t be very practical. Practically, we see mAh used in any electronic device with a battery, from phones to Bluetooth speakers .
