The Impact of Photosensitive Compounds on Solar Cell Efficiency: A Comprehensive Study

Abstract

Photosensitive substances are essential to solar cell efficiency, which is a crucial factor in determining the amount of renewable energy produced. The impact of both organic and inorganic photosensitive compounds on photon absorption, charge separation, and energy conversion efficiency has been brought to light by recent developments in material science. The chemical structures, light-harvesting capacities, and integration of diverse photosensitive compounds into various solar cell technologies are all thoroughly examined in this work. The study aims to establish a relationship between compound characteristics and solar cell efficiency by examining empirical data and previous research (Smith, 2020).

            The metrics included fill factor, power conversion efficiency, open-circuit voltage, short-circuit current density, and other elements. The results showed that ruthenium-based dye had the highest power conversion efficacy (8.7) and light harvesting efficiency (86), followed by organic dye (6.9%) and natural dye (4.1%). Another feature that showed ruthenium dyes were stable enough to retain up to 92% of their efficacy after being exposed to light for 120 hours was the stability analysis. It shows the importance of photosensitive materials in increasing solar cell efficiency and completes the design of more efficient dyesensitive solar technology.

            The study examine how these substances can be used in organic photovoltaics, dye-sensitized solar cells, and perovskite solar cells to improve photovoltaic performance. The results are intended to guide the development of next-generation solar cells with maximum potential for sustainability and energy conversion. To provide a comprehensive view of the topic, the study combines experimental observations with a survey of the literature using both qualitative and quantitative approaches (Lee, 2019).
