Abstract
Photovoltaic is one of the promising renewable sources of power to meet the future challenge of energy need. Organic and perovskite thin film solar cells are an emerging cost-effective photovoltaic technology because of low-cost manufacturing processing and their light weight. The main barrier of commercial use of organic and perovskite solar cells is the poor stability of devices. Encapsulation of these photovoltaic devices is one of the best ways to address this stability issue and enhance the device lifetime by employing materials and structures that possess high barrier performance for oxygen and moisture. The aim of this review paper is to find different encapsulation materials and techniques for perovskite and organic solar cells according to the present understanding of reliability issues. It discusses the available encapsulate materials and their utility in limiting chemicals, such as water vapour and oxygen penetration. It also covers the mechanisms of mechanical degradation within the individual layers and solar cell as a whole, and possible obstacles to their application in both organic and perovskite solar cells. The contemporary understanding of these degradation mechanisms, their interplay, and their initiating factors (both internal and external) are also discussed.
Highlights
Organic photovoltaic (OPV) and Perovskite solar cell (PSC) are promising emerging photovoltaics thin film technology
Effective thin film encapsulation is crucial to prevent the permeation of water vapour and oxygen for achieving the stability and desired life times of organic and perovskite solar cells
New materials and technology are required to satisfy the requirements of encapsulation to prevent the permeation of moisture and oxygen for the reliability and stability of devices
Summary
Organic photovoltaic (OPV) and Perovskite solar cell (PSC) are promising emerging photovoltaics thin film technology. The power conversion efficiency (PCE) of OPV devices have overpassed 14% for single junction and 17% for tandem devices to date with the development of low band-gap organic materials and device processing technology [2,3,4,5]. PCE of PSCs over 23.3% has shown promising future directions for using in large-scale production, together with traditional silicon solar cells [6]. Low-temperature (
