Solar cells used in photovoltaic (PV) crystalline silicon modules commonly feature grid fingers and bus bars as front contacts. The grid fingers and bus bars partially block the sunlight from reaching the semiconductor layers of a solar cell and therefore reduce the efficiency of a solar module. In this paper, we present experimental results of different technologies to reduce the shadowing effect that bus bars and grid fingers impose. We focus on two technologies that can be easily integrated…

Approaches to improving energy yield from PV modules
PV modules were fabricated that incorporated various methods to increase the amount of light which is ultimately transmitted to the solar cell in order to improve energy yield. The techniques
Reducing shadowing losses in silicon solar cells using cellulose nanocrystal: polymer hybrid diffusers.
Simulations showed that the CNP diffuser is an excellent candidate for reducingshadowing losses within a wide range of incident angles, as it can reduce more than 30% of shadowing losses at normal incidence, and nearly 50% of the lost light can be recycled at the incident angle of 60°.

A simple ray tracer to compute the optical concentration of photovoltaic modules
In a conventional photovoltaic module, some light that falls between the solar cells is internally reflected onto the cells via the backsheet and the glass–air interface of the module; thus, a module
