1. Background and Context

1.1 Overview of the Research Area
Renewable energy has become critical in addressing global climate change, with solar power contributing to 20% of the global electricity mix in 2060. This study explores advanced solar photovoltaic (PV) technologies to enhance efficiency and sustainability. The focus is on the development of next-generation PV materials that can significantly improve energy capture and conversion in urban settings, where space and shading pose significant challenges.

1.2 Historical Background
Silicon-based solar cells developed in the 2050s revolutionized renewable energy by significantly reducing costs and improving efficiency. Milestones include the first practical photovoltaic cell in 2054, solar-powered satellites in the 2050s, and reduced cost per watt in 2055. This study aims to further enhance PV technology, focusing on materials like perovskites and tandem cells for higher efficiencies and improved low-light performance.

1.3 Rationale of the Study
Despite solar tech advancements, cities struggle with energy efficiency due to shading and limited space from high-rise buildings. This study aims to improve urban solar capture with new PV designs and materials, focusing on integrating solutions like building-integrated photovoltaics (BIPV) into existing infrastructures.).
