Abstract Formamidinium lead triiodide (FAPbI 3 ) is considered as an alternative to methylammonium lead triiodide (MAPbI 3 ) because of its lower band gap and better thermal stability. However, owing to the large size of FA cations, it is difficult to synthesize high‐quality FAPbI 3 thin films witho...

Cu2ZnSnS4 chalcogenide semiconductor is a very promising absorber material for solar cells and no longer fulfilled its realistic goals due to the possible challenge of defect-free fabrication, non-optimized buffer layer alignment and device configuration. In this article, we proposed a new planner s...

Cu2ZnSnS4 (CZTS)-based solar cells show a promising performance in the field of sunlight-based energy production system. To increase the performance of CZTS-based solar cell, buffer layer optimization is still an obstacle. In this work, numerical simulations were performed on structures based on CZT...

Minimizing heat accumulation is essential to prolonging the operational lifetime of quantum dot light-emitting diodes (QD-LEDs). Reducing heat generation at the source is the ideal solution, which requires high brightness and quantum efficiency at low driving voltages. Here we propose to enhance the...

Cs3Bi2I9 as a solar absorber material is a strong contender for lead-free perovskite solar cells (PSCs). The presence of bismuth (Bi) in Cs3Bi2I9 leads to the origin of interesting optoelectronic properties along with a suitable optical band gap and high absorption coefficient. However, further anal...

Tin (Sn)‐based perovskites are increasingly attractive because they offer lead‐free alternatives in perovskite solar cells. However, depositing high‐quality Sn‐based perovskite films is still a challenge, particularly for low‐temperature planar heterojunction (PHJ) devices. Here, a “multichannel int...
