Transparent photovoltaic (TPV) devices have the potential to revolutionize photovoltaic (PV) technology by enabling on‐site generation while minimizing visual impact. However, a major challenge in the development of TPV, as well as for many PV technologies, is the open‐circuit voltage (Voc) deficit, which limits their efficiency. In this work, the development of wide‐bandgap inorganic‐based TPV devices is reported with a focus on low‐cost, earth‐abundant, stable, and nontoxic materials. The device structure consists of an ultrathin hydrogenated amorphous silicon (a‐Si:H) absorber and metal‐oxide layers as selective contacts. Herein, novel approach is presented to significantly improve device performance, especially in Voc, by introducing molecular dipoles in the device electron‐transport layer. By incorporating polyethyleneimine or poly(amidoamine) G1 and G2 dipoles, Voc (from 410 mV up to 638 mV) is significantly increased without sacrificing the average photopic transmittance of the device, leading to a record efficiency for this particular approach in TPV. Measurements confirm excellent long‐term stability. This approach can potentially allow tuning the work function of the selective contacts enabling the use of low‐cost, earth‐abundant materials that are not optimized for a particular absorber. Furthermore, this solution circumvents the issue of low Voc by a simple interface treatment.

resources involves the conversion of sunlight energy directly to electricity using photovoltaic technologies. In this regard, extensive research efforts are being been focused on the development of new photovoltaic devices, including organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). [1,2] Such devices benefit from the numerous advantages of organic compounds, which can be chemically modified to achieve the desired device performance. [3][4][5][6] With decades of study, organic semiconductors now exhibit outstanding electronic and structural properties that has led to the fabrication of innovative organic devices with impressive output characteristics, including high field-effect mobility (10 cm 2 V −1 s −1 ) in organic field-effect transistors (OFETs), and high efficiencies of 17% in OSCs and 25% in PVSCs. [7][8][9][10][11][12][13][14][15] Furthermore, the inexpensive access of organic materials that can be processed through low-cost solution processing methods is widely attractive for practical applications that require the light-weight devices to be flexible and transparent. [16] The performance of organic electronic devices depends primarily on the properties of the active layer and electrodes, but also relies heavily on the properties of the various device interfaces. In recent years, a remarkable advancement in device Compared to their inorganic counterparts, organic optoelectronic devices receive considerable attention due to their lower cost, mechanical flexibility, bandgap engineering, and solution processability. In particular, achieving sustainability in solar cells and light emitting devices is an important milestone in the development of green electronics. This has facilitated a close collaboration between different technological fields, opening new ways for low-cost production and application of biomaterials. Recently, biomass materials, mainly derived from plants, animals and microorganisms, have emerged as effective candidates to modify the interfacial properties, and thus enhance the performance, lifetime, and stability of organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). Compared to the commonly used synthetic interfacial materials, the use of biomass interlayer materials (BIMs) is still in its embryonic stages; however, their nontoxicity, biorelevance, sustainability, special proton conductivity, and rich functional groups are stimulating researchers around the globe to fabricate novel devices with improved efficiency. Herein, a comprehensive review of BIMs and their importance in next-generation optoelectronic devices is provided. A welltargeted comparison between the electrical and physical properties of different BIMs is provided, and how such characteristics improve the performance of three key optoelectronic devices: OSCs, PVSCs and OLEDs, is discussed.

Solar photovoltaics (PV) are poised to be crucial in limiting global warming by replacing traditional fossil fuel generation. Within the PV community, crystalline silicon (c‐Si) solar cells currently dominate, having made significant efficiency breakthroughs in recent years. These advancements are primarily due to innovations in solar cell technology, particularly in developing passivating contact schemes. As such, this review article comprehensively examines the evolution of high‐efficiency c‐Si solar cells, adopting a historical perspective to investigate the advancements in passivation contact techniques and materials to state‐of‐the‐art cell designs.
