🌻 What are N-type solar cells?
🌻 Solar cells are large area p-n junctions. An N-type solar cell consists of a thin p-type silicon (doped with boron) layer over a much thicker n-type silicon (doped with phosphorus) layer. Electrical contacts are applied to both sides. The p-side is the front side facing the sun. It is given an antireflective coating, over which is pasted a clear adhesive (for instance EVA) which holds the front protective glass layer.
🌻 Note: Do not be alarmed. This dope is legally recommended, not by doctors, but by engineers!
🌻 Why N-type solar cells are less common
Currently most of the crystalline solar cells are p-type. This is because of a lower cost of production of p-type. The reasons are probably attributable to history of development of solar cells. But performance wise, n-type solar cells can give much better efficiency compared to p-type solar cells. Two main factors account for this. Firstly, p-type material has boron (trivalent) doping. In the presence of light and oxygen boron undergoes some undesirable action, which reduces efficiency of conversion. This is called Light Induced Degradation or LID.
🌻 Disadvantages P-type solar cells
To understand the second disadvantage, note that sunlight breaks loose an electron hole pair. If this takes place in the n-type region, the holes are minority carriers in this (n-type) region. A hole while drifting could be filled by absorbing one of the free electrons which are the majority carriers here. In this case the solar energy absorbed will be lost as heat, and only heat up the cell. Our aim is to allow the holes to reach the depletion region where it will be swept by the electric field to the p-type material, and on to the anode. In other words, the diffusion length of minority carriers must be as long as possible to allow better solar efficiency. In the n-type cell this diffusion length of minority carriers is more than in the p-type cells, because the n-type is less affected by minority impurities. Since n-type cells have a better diffusion length for their minority carriers, they have a better conversion efficiency.
🌻 For this reason the relevant industry is engaged a lot of research in this direction to permit more cost effective production of n-type cells.🌻

🌻 PID & LID: Devastating Phenomena for PV plants
🌻 PID & LID – two different kinds of Induced Degradation of PV modules. In the first case Potential Induced Degradation (PID) conducted by high voltages, and the other Light Induced Degradation (LID) conducted by sunlight (real or simulated).
🌻The purpose of this article is not to extendedly describe the micro-scale source of these phenomena, but, some real consequences at the MW scale PV plants, considering the basis of a PV project – the simulation by software.
🌻 LID – Light Induced Degradation
Silicon PV modules have a natural degradation due to the physical reactions (electrons flow) through the p-n junctions of a PV module. Nevertheless, a concept of (initial) “Power Stabilization” should more widely be used, recognized and taken into account.
🌻 “Power Stabilization” is an initial degradation occured when modules are exposed to sunlight. The average percentage of power loss for the first year is usually advertised (in manufacturer’s datasheets) to be arround 3%.
🌻 “Power Degradation” is nowadays advertised to be around 0,8% for the following years, i.e., after the so called “Power Stabilization”.
🌻 The graphic below summarizes the deviation of Power (Pmpp) of Mono-crystalline and Poly-crystalline PV modules (a total of 58 modules, different brands) relative to manufacturer’s data. The test was done to new modules, exposed to real sunlight 25 kWh/m^2 (which means 3 days according to testing site, south of Portugal). After the irradiation exposure, modules where subjected to Maximum Power Determination under STC conditions.
