Abstract

Emisi karbon dioksida (CO2) di atmosfer yang yang meningkat seiring dengan berjalannya waktu dapat memberikan efek yang signifikan terhadap pemanasan global. Teknologi penangkap karbon merupakan salah satu upaya untuk mengurangi emisi CO2 tersebut. Dalam penelitian ini, disintesis karbon berpori sebagai material adsorben untuk aplikasi penangkap karbon dioksida dari biomassa batang jagung dengan doping atom N yang berasal dari urea (CH4N2O) dan aktivator KOH. Variasi rasio massa raw material:KOH:urea yang digunakan adalah (1:1:1), (1:1:2), dan (1:1:3). Keberhasilan doping N pada karbon diuji dengan karakterisasi EDS, FTIR dan XPS. Hasil pengukuran EDS menunjukkan adanya kandungan atom C, O yang berasal dari biomassa dan unsur N yang berasal dari doping. Spektra FTIR untuk semua variasi rasio doping, menunjukkan adanya gugus fungsi C-N pada bilangan gelombang 1066-1124 cm-1, yang menunjukkan bahwa doping N telah berhasil dilakukan pada karbon. Pengukuran XPS menunjukkan adanya ikatan antara atom C dan atom N dalam bentuk Pyrrolic N, Pyrridinic N, dan Oxidized N dengan energi ikat masing-masing 400,1 eV, 398,2 eV, dan 404,6 eV. Hasil EDS, FTIR dan XPS ini menunjukkan bahwa karbon berpori dengan doping N telah berhasil disintesis. Foto SEM menunjukkan terbentuknya pori atau rongga yang tidak terstruktur akibat aktivator KOH dan doping N. Hasil analisis pengukuran BET menunjukkan bahwa rasio (1:1:2) menghasilkan luas permukaan paling tinggi, yaitu 563,494 m2/g, volume total pori sebesar 0,397 cm3/g, dan diameter rata-rata pori sebesar 2,82 nm. Dengan demikian, sampel (1:1:2) memiliki potensi yang paling besar untuk diaplikasikan sebagai material karbon berpori penangkap karbon dioksida.

Abstract

The transition towards new and renewable energy in an effort to address environmental issues and limitations of conventional energy reserves remains a global priority to this day. Solar energy, with photovoltaic technology, is one of the promising options in reducing the impact of conventional energy on the environment. This is supported by the fact that solar energy is a sustainable energy source and one way to reduce dependence on fossil energy. Solar cells or photovoltaic cells are devices made of semiconductor materials that can convert solar energy into electrical energy. In the first generation, solar cells were divided into monocrystalline, polycrystalline, and III-V single junction based on GaAs. This article examines the characteristics of first-generation silicon-based solar panels, including efficiency, absorption, and light transmission, which dominate the global market. This review aims to provide an in-depth understanding of the factors that affect the performance of silicon-based solar cells, for the development and application of solar cell technology in the future.

Abstract

Efficiency and cost are important points in the development of the renewable energy industry, especially solar cells. While the first generation of crystalline silicon-based solar cells had the biggest constraint in cost, the second generation of thin-film solar cells is trying to offer innovations with relatively lower cost but high flexibility compared to the first generation. This article explores the essential developments in the invention of second-generation thin-film solar cells, including materials, performance, and technology. Through their respective fabrication processes, ultra-thin-film solar cells based on various materials such as amorphous silicon, Cadmium Telluride/Cadmium Sulfide (CdTe/CdS), and Copper Indium Gallium Selenide/Copper Zinc Tin Sulfide (CIGS/CZTS) were discovered. With these types of thin-film cells as well, the use of solar cells is more flexible for various applications mainly due to their lighter weight. Although the efficiency of their photovoltaic effect or light-to-electricity conversion is generally lower than that of crystalline silicon solar cells, these thin-film solar cells are efficient in absorbing light in dimmer conditions.

Abstract

Perovskite is one of the materials used for solar panels that offers high efficiency comparable to conventional silicon-based solar cells. This article aims to analyze the latest developments in perovskite solar cells from various important aspects, starting from material development, various fabrication techniques, as well as opportunities and challenges in its development. Perovskite is a type of material that has a crystal structure with the chemical formula ABX3. Perovskite fabrication can be done using various methods such as spin coating, spray coating, doctor blading, inkjet printing and others. In its development, various innovations have been made, such as the development of cells without a hole transport layer (HTL-free), the addition of ethylenediammonium cations (en), and efforts to replace lead with more environmentally friendly materials such as tin. The results of the study showed that the power conversion efficiency (PCE) of perovskite solar cells has reached more than 25%. Although this development is promising, there are still major challenges in maintaining the long-term stability of the device, especially related to degradation due to humidity, heat, and prolonged lighting. The development of fabrication techniques that can mass produce perovskite solar cells with high performance and stable reliability is essential. With continued research and material innovation, perovskite solar cells have great potential in supporting sustainable clean energy transitions such as their applications in building-integrated photovoltaic (BIPV) systems, wearable electronic devices, and agrivoltaic systems.

Abstract

One of the emerging technologies that has gained attention as an alternative for meeting renewable energy demands is the Organic Solar Cell (OSC). OSC is a type of photovoltaic device that utilizes organic electronic materials. The fundamental operating principle of OSC is based on the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO), with organic compounds serving as the active materials, enabling the conversion of light energy into electricity. Research on OSC has continuously evolved over the years to achieve optimal performance. The substrate/transport layer, which serves as the foundation for the organic active layer in OSC, can be categorized into several types, including ITO-based OSC, conducting polymer-based OSC, silver nanowire-based OSC, metal-based OSC, and graphene-based OSC. Organic solar cells offer several promising prospects, such as relatively low production costs, as well as flexible and transparent design features. However, OSCs also face several challenges, including relatively low efficiency and environmental stability concerns. Addressing these challenges is crucial to unlocking the full potential of OSC technology. This article first provides a general overview of OSC advancements, followed by a summary and analysis of its working principles, performance parameters, and structural components. Finally, we explore recent breakthroughs in OSC development in detail.
