The energy scenario today is focused on the development and usage of solar cells, especially in the paradigm of clean energy. To readily create electron and hole pairs, solar cells utilize either photoactive or photosensitive components. A bulk heterojunction (BHJ) is a nanolayer consisting of donor and acceptor components with a large interpenetrated acceptor and donor contact area. In this context, a mix of P3HT and PCBM offers novelty for its use as an acceptor as well as a donor. In the work presented here, we address the mechanism of modelling and characterization of a BHJ-based polymer solar cell. Here, a new design of BHJ polymer solar cells have been designed, modelled, using Silvaco TCAD in the Organic Solar module, and matched with an already assembled device having similar features. Using this model, we have been able to estimate key parameters for the modelled devices, such as the short-circuit current density, open-circuit voltage, and fill factor with less than 0.25 error index compared to the fabricated counterpart, paving the way for fabless polymer solar cell design and optimization.

体异质结聚合物太阳能电池的设计、电气和光学建模

今天的能源场景集中在太阳能电池的开发和使用上，尤其是在清洁能源的范式中。为了容易地产生电子和空穴对，太阳能电池利用光敏或光敏组件。本体异质结 (BHJ) 是一种纳米层，由供体和受体成分组成，具有大的互穿受体和供体接触面积。在这种情况下，P3HT 和 PCBM 的混合物为其用作受体和供体提供了新颖性。在这里介绍的工作中，我们解决了基于 BHJ 的聚合物太阳能电池的建模和表征机制。在这里，使用有机太阳能模块中的 Silvaco TCAD 设计、建模了 BHJ 聚合物太阳能电池的新设计，并与具有类似特征的已组装设备相匹配。使用这个模型，
