A "photoelectrochemical cell" is one of two distinct classes of device. The first produces electrical energy similarly to a dye-sensitized photovoltaic cell, which meets the standard definition of a photovoltaic cell.

Photoelectrochemical cells (PECs) extract electrical energy from light, including sunlight. Each cell consists of one or two semiconducting photoelectrodes and also auxiliary metal and reference electrodes immersed in an electrolyte.

Photoelectrochemical cells (PEC) 实质上是基于太阳能电池的一个半导体-电解质界面。 早在1970年开始，就对这种易于形成的完美固液界面进行了大量的研究。 但是，这个研究热度急剧下降，直到出现染料敏化太阳能电池 (DSSC)-基于非常高的基底面积，由分子厚度的染料层可产生很好的光吸收 (即产生光电流)。 这个想法很快被 半导体敏化剂 研究所采用。 但在相当长的一段时间内，这种思路在半导体-敏化太阳能电池的研究都比较分散且进展缓慢。 但在过去的5年，发生 …

2016年4月30日 · This chapter serves as a reference for the basic design, testing, and efficiency definitions for photoelectrochemical (PEC) water-splitting cells. In particular, design principles and standards are given for PEC cells that utilize thin film semiconductor...

A photoelectrochemical cell (PEC) is a device that converts solar energy (light) into chemical energy or electricity. Light activates a semiconductor or photosensitizer component within the cell and either: Generates electrical energy, similar to how dye-sensitized solar cells work.

The PEC cell, unlike the traditional solar cell, converts solar energy to chemical energy, and this chemical energy is embodied in a chemical bond. How Does a PEC Cell Work? A PEC cell consists of two sides, the anode and the cathode (Fig. 1).

使用吸收光的半导体电极利用阳光的能量来电解水的尝试可以追溯到40多年前被广泛引用的 Fujishima 和 Honda 的工作，他们使用n型金红石（TiO2）单晶通过光生空穴驱动水的氧化，同时在铂负电极上生成氢。他们的论文发表于1973年石油危机爆发之时，引发了十多年的持续努力，以开发稳定、高效的太阳能水分解光电电化学（photoelectrochemical, 简称PEC）装置。 令人印象深刻的高效系统是在实验室中开发的，例如使用单晶掺磷 磷化铟 作为光电阴极。 1998年， …

2001年11月15日 · Research on photoelectrochemical cells went through a frantic period after the oil crisis in 1973, which stimulated a worldwide quest for alternative energy sources. Within a few years well over...

Photoelectrochemistry (PEC) is a multidisciplinary field involving surface science, electrochemistry, solid-state physics, and optics. This article focuses on the electrochemical aspects, whereas sevaral sources listed in the Bibliography, provide more detailed information on other aspects of the field.

The PEC cell consists of a photoactive semiconductor working electrode (either n-or p-type) and counter electrode made of either metal (Pt) or semiconductors. Both electrodes are immersed in the electrolyte containing suitable redox couples.
