The Progress of Hole Transport Layer for Enhancement of Performance and Charge Transport Stability in Perovskite Solar Cell | Book Publisher International

 

Recently, a new generation of photovoltaic solar cell materials has been developed. Featuring special characteristics such as a high absorption coefficient, an ideal band gap, high defect tolerance, and a long carrier diffusion length. These advancements have led to experimental improvements in the performance of both organic and inorganic hybrid lead/tin halide perovskite solar cells. However, to complete the photovoltaic process, suitable electrodes and transport materials are essential. This is due to the phenomena of charge carrier separation, transportation, and charge collection at the interfaces between layers. As a result, the power conversion efficiency (PCE) has improved from 3.9% to 33.6%. This book chapter focuses on the progress made in enhancing hybrid perovskite solar devices, emphasising the role of charge generation through the photovoltaic effect and the stability of charge using conjugated polymers.

Metal Oxide Thin Films Used as Solar Absorbers: Review| Chapter 1 | Progress in Chemical Science Research Vol. 1

Metal oxide materials are gaining popularity due to their remarkable physical, optical, and electrical qualities. Laser devices, supercapacitors, solar cells, biosensors, biomedicine, photo catalysis, and luminous materials are just a few of the uses for these thin films. Many scientists have documented the synthesis of metal oxide films utilising various deposition processes such as physical and chemical approaches. Characterization is a crucial step in ensuring that the thin films produced can be utilised for certain applications. Based on a literature study, the major goal of this work is to report on the creation or improvement of thin film based solar cells, perovskite solar cells, and dye sensitised solar cells. The photovoltaic properties (short-circuit current, open-circuit voltage, fill factor, and efficiency) of solar cells made under diverse circumstances were examined. The many types of solar cells were built, and the efficiency of power conversion was highlighted. Metal oxide films might be used as an electron transport layer, electron conducting medium, anti-reflecting layer, and hole transport material, according to the overall experimental results.
