GCL Technology has unveiled its revolutionary #perovskite-#silicon tandem module, set to disrupt the #solar industry with its #competitive pricing and high efficiency. The #company claims these modules will cost just $0.075 per watt, which is half the price of current #crystalline silicon #modules. The pure perovskite module boasts an #efficiency of just over 19%, while the tandem module impressively achieves over 26% efficiency. Mass production is scheduled to begin in late 2025. GCL anticipates the tandem module efficiency to exceed 27% next year, with ambitious plans to surpass 30% in the future.

Increasing voltage in cadmium telluride solar cells through nickel oxide back buffer layer: Cadmium telluride solar cells are commonly based on non-ohmic back contacts that affect the device open-circuit voltage. Researchers in the United Kingdom sought to address this issue by adding a nickel oxide back buffer layer, which formed an ohmic back contact and increased open-circuit voltage levels. #Renewables #Energy #Technology

First attempt to design CIGS/SWCNT tandem solar cells promises 38.91% efficiency: Indian researchers have proposed to build tandem solar cells based on a CIGS top cell and a bottom cell relying on a single-walled carbon nanotube (SWCNT) absorber. SWCNTs were previously used in solar research as an alternative to conventional metal grid contacts or hole transport layers (HTLs), as they combine optoelectronic properties, flexibility, chemical stability, and simple transfer protocols. #ModulesUpstreamManufacturing #TechnologyandRD #photovoltaic

I'm thrilled to share about our jointly collaborated work, that has been published in the prestigious Solar Energy journal (Elsevier, Cite score:13.1, IF:6.7, Q1, SCIE) Article Title: Efficiency enhancement of hybrid-solar cell by optimizing CuSCN and V2O5 based dual hole transport layer Publication Date: 31/05/2024 In this paper, we explore the third generation solar cell technologies which shows superior performance in terms of conversion efficiency. This simulation study provides detailed modeling and analysis of hybrid solar cells (HSC). Proposed work seeks to boost device efficiency by introducing a novel dual hole transport layer (HTL). The HSC achieves highest efficiency, utilizing a dual combination of the HTLs in the Copper materials, specifically, Copper zinc tin sulphide (CZTS). In the current simulation, TiO2 and both V2O5, and CuSCN are employed as carrier transport layers (CTL). The dual hole transport layer enhances the open-circuit voltage (VOC)and efficiency upto 23.45 %. Additionally this work examines thickness, defect density, and temperature dependencies on the targeted device structure. https://lnkd.in/gnVFZixy A huge thank you to all the co-authors, collaborators for their support and contributions.

Smart optimization paves the way for improved silicon solar cell performance Graphical abstract. Credit: ACS Applied Materials & Interfaces (2024). DOI: 10.1021/acsami.3c16202 In the face of the ever-growing threat of climate change, the past few decades have witnessed great progress in solar energy technology. In particular, silicon heterojunction (SHJ) solar cells have become a hot topic in this field since they can reach very high energy conversion efficiencies. The performance of SHJ solar cells depends, in great part, on the quality of their passivation layer. This thin film made of intrinsic hydrogenated amorphous silicon (i-a-Si:H) helps prevent light-excited charge carriers (like electrons) from being lost through the process of recombination. Recently, researchers from the Japan Advanced Institute of Science and Technology (JAIST) have been focusing on using a method known as catalytic chemical vapor deposition (Cat-CVD) to form thin passivation films on SHJ solar cells. Overall, Cat-CVD is an attractive and highly efficient technique that can deposit films without causing damage to the substrate, unlike plasma-based deposition methods. However, determining the optimal deposition conditions to obtain high-quality i-a-Si:H films has proved difficult. This is because Cat-CVD has several adjustable parameters, including substrate temperature, gas flow rates, and deposition time. Thus, determining the best combination through trial and error is extremely time consuming. Now, in a recent study published in ACS Applied Materials and Interfaces, a research team led by Professor Keisuke Ohdaira from JAIST has developed an innovative and efficient strategy to obtain the optimal deposition conditions for Cat-CVD. The study was co-authored by Ryota Ohashi, a Master's student, Research Assistant Professor Huynh Thi Cam Tu and Senior Technical Specialist Koichi Higashimine from JAIST along with Dr. Kentaro Kutsukake, a researcher at RIKEN.#solarenergy #greenenergy #optimization #techtalks
