一种独特的太阳能电池制造过程已经开发出使用天然花青素染料提取的浆果。它可以用最少的资源复制，以便为低年级本科生学习生物提取，物理化学和光谱学以及环境科学和电子转移的基本原理提供跨学科的方法。电子转移是驱动地球上生命过程的能量学的基础，发生在活细胞的线粒体膜和绿色植物和藻类的光合细胞的类囊体膜中（1）。虽然我们依赖于这种电子和能量转移的石油和农产品，但21世纪世纪最大的挑战之一是，我们还没有创造出可用于直接利用这种能量的最终来源的设备。因此，创建了一个实验室程序，以便在三小时的实验室时间内说明自然和人造太阳能转换之间的联系。
A unique solar cell fabrication procedure has been developed using natural anthocyanin dyes extracted from berries. It can be reproduced with a minimum amount of resources in order to provide an interdisciplinary approach for lower-division undergraduate students learning the basic principles of biological extraction, physical chemistry, and spectroscopy as well as environmental science and electron transfer. Electron transfer is the basis of the energetics that drives the processes of life on Earth, occurring in both the mitochondrial membranes of living cells and in the thylakoid membranes of photosynthetic cells of green plants and algae (1). Although we depend on the petroleum and agricultural products of this electron and energy transfer, one of the greatest challenges of the 21st century is that we have yet to create devices that can be used to tap directly into the ultimate source of this energy on an economic scale. An experimental lab procedure was therefore created in order to illustrate the connections between natural and man-made solar conversion within a three-hour lab period.
