Summary: This paper proposes an alternative device structure for GaAs solar cells using zinc oxide as an electron-selective contact, achieving an efficiency of 18.5% with the potential for further optimization to over 25%. Detailed analysis shows higher efficiency and carrier selectivity compared to homojunction cells grown under similar conditions, while also reducing the complexity and cost of epitaxially grown cells.

Summary: In this study, a small molecule, N-methyl-4-piperidone (NMPD), was used as an interfacial passivation filler between the perovskite and electron transport layers in inverted organic-inorganic hybrid CH3NH3PbI3 perovskite solar cells. The filler effectively reduced non-radiative charge recombination and improved electron extraction efficiency, resulting in an increased power conversion efficiency (PCE) and enhanced stability of the perovskite devices.

Summary: Ultrathin solar cells, with one order of magnitude smaller thickness compared to conventional cells, reduce material usage and allow the use of lower-quality materials. Efficient photonic light-trapping is required to compensate for the limited absorber thickness. Quasi-random photonic crystals, which are more robust under angle and thickness variations, are predicted to provide high efficiency light-trapping. In this study, we experimentally demonstrate the use of quasi-random photonic crystals fabricated by polymer blend lithography for light-trapping in ultrathin GaAs cells, achieving an efficiency of 22.35% under the global solar spectrum.

Summary: This study presents a facile yet excellent approach to enhance the thermal stability and power conversion efficiency (PCE) of perovskite solar cells (PSCs) by introducing triphenylphosphine (TPP) as a passivator. The TPP-passivated devices exhibited superior ambient and thermal stability, with a retention of 71% of its initial PCE after long-term storage at high temperature and humidity.

Summary: A novel strategy using aluminum-doped zinc oxide (AZO) films for front passivation of solar cells is reported, achieving a high efficiency of 15.07% in CIGS solar cells without alkali metal post treatment and anti-reflective layer. The AZO films provide good passivation due to simulated field passivation. In addition, the films have high optical transparency, conductivity, and can be fabricated cost-effectively at room temperature. The study is significant for advancing the development of CIGS-based photovoltaic devices and can also be applied to other solar cells.
