“…Interdigitated Back Contact solar cells developed by Richard Swanson since 1984 [48] to date at Sunpower Corp do not use front side metallization at all, but instead place both electrodes as well as the p-n junction on the rear side of the solar cell. The entire sunny side of the solar cell is covered with a highly optimized anti-reflective coating which must also provide excellent electronic passivation to avoid front surface recombination of minority charge carriers generated close to the sunny side of the solar cell far away from the p-n junction.…”

This chapter provides an overview of the physical challenges and concepts for light management in solar modules, as well as established solutions and current and novel approaches to realize the ambitious goal of the International Technology Roadmap for Photovoltaic (ITRPV) roadmap. Focusing on the typical construction of the crystalline silicon solar modules, a description of the physical phenomena that determine the losses of a light beam on its path through the several layers of a module is provided. The physics of anti-reflection and light trapping/light redirection concepts is provided with the report on experimental and simulation techniques to assess the achievable progress under consideration of the real field situation, expressed in parameters like spectral distribution and varying incidence angle of sunlight, or diffuse lighting. The chapter discusses technological solutions that are already implemented, that are on the threshold to industrial use, and novel concepts currently under basic investigation

“…A prudent approach to minimize the Si-M contact area (both at the front and back) is through appropriate grid design. This consideration has led to the design of point-contact and buried-contact cells [20,21]. This feature will also minimize the shadow loss for the incident light (except for back-contact cells).…”

“…The distance between fingers therefore had to be very lo,v and to minimise shadowing, the fingers had to be very narrow. [5] A word on the history of the solar cell. In 1977 Burgess et al [2] introduced a cell with what was at the time a high efficiency of 15% at 50-fold solar radiation.…”

“…In 1980 Khemthong et al [3] increased this value to over 20% (at 40 suns). A decisive improvement was achieved by Sinton et al [4] and Swanson et al [5] when they implemented and improved the structure :;uggested by Lammert et al [6] in 1974, the IBC [Interdigitated Back Contact]. As the name suggests, both n+ and p+ diffusion structures (Figure 8.1) and therefore also both connection contacts lie on the back of the cell.…”
