Perovskite solar cells : out of the lab and into a panel
Abstract/Contents
- Abstract
- Organic-Inorganic Metal Halide Perovskites are an increasingly promising next-generation solar absorber technology on pace to take the solar industry by storm. Although efficiency is the oft quoted figure of merit for solar cell technologies, their energy yield is a potentially more relevant metric when comparing different solar technologies as energy yield considers local weather conditions for a desired installation location. Energy yield calculations are used to compare the performance of various perovskite modules under a variety of weather conditions. As perovskites progress towards commercialization, problems that are not easily explored in typical laboratory conditions become more important. When a single solar cell in a panel is shaded, the illuminated cells that are connected in series with it can place a large reverse bias on the shaded cell to attempt to force current through it. While this situation can allow the panel to continue to produce power, it can cause significant problems for the shaded cell. Specifically, in the case of perovskite solar modules, a combination of Joule heating and irreversible electrochemical reactions will degrade the cell. We explore how many solar cells can be protected by one bypass diode in both single junction and multijunction perovskite modules. We also discuss how one might integrate bypass diodes into modules that are made by connecting singulated cells with wires versus those that are monolithically integrated. We show that an advantage of perovskite-silicon tandems is that the silicon substantially increases the breakdown voltage and thereby the number of cells that can be protected by one bypass diode. It is well known that stability is a major concern that must be addressed before perovskites enter the solar market. Accelerated aging is commonly used to evaluate the viability of any new technology on a reasonable time scale by probing various degradation mechanisms. Thermal acceleration factors for perovskites are explored as well as their relationship with the residual stress in the thin film absorber.
