Embodiment Construction

[0088] The present disclosure is further illustrated by the following experimental examples and examples. It should be understood that the subject matter disclosed in the Experimental Examples and Examples is for the purpose of illustration and is not intended to limit the scope of the present invention.

[0089] Solution-processed bulk heterojunction organic solar cells (BHJ OSCs) have been well-studied and considered as one of the most promising next-generation green technologies to replace inorganic solar cells because of their solution processability, low cost, and light weight. , and a high degree of flexibility.

[0090]In the past decade, intensive research has been conducted on the development of new organic semiconducting materials, including polymers and small molecules for BHJ photovoltaic devices. Although great progress has been made in polymeric electron donor materials, recent studies have shown that polymers are not the only way to achieve proper interpenetrat...

Abstract

Provided are porphyrin small molecules substitutes designed and synthesized for bulk hetero junction (BHJ) organic solar cells (OSOs). Provided are synthesized materials with strong and ordered self-assembly property, leading to form bicontinuous, interpenetrating networks which are required for efficient charge separation and transport in organic solar cells. The power conversion efficiency (PCE)of the solar cells devices based on the embodiments have the highest PCE among the solution-processed BHJ solar cell based on porphyrin small molecules up to date.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 356,018, filed June 29, 2016, and U.S. Nonprovisional Patent Application Serial No. 15 / 635,563, filed June 28, 2017, the disclosures of which are incorporated by reference into this article. technical field [0003] The porphyrin small molecules involved in the present disclosure have applications in bulk heterojunction (bulk heterojunction, BHJ) organic solar cells (organic solar cells, OSCs). The provided synthetic materials exhibit robust and ordered self-assembly properties, leading to the formation of bi-continuous, interpenetrating networks, which can be exploited for efficient charge separation and transport in organic solar cells. Compared with traditional solution-processed BHJ solar cell devices based on porphyrin small molecules, the power conversion efficiency (PCE) of the solar cells in the embodiments according to the pre...
