Paperback. Reduction of optical losses in both mono and multicrystalline silicon solar cells by surface texturing is one of the important issues of modern silicon photovoltaics. Texturing of the front surface of silicon solar cells has been modeled and analysed with reference to the reduction in reflection co-efficient and increase in optical trapping. Significant enhancement in open circuit voltage and short circuit current has been achieved through such texturing of the front surface of mono-silicon solar cells. A proper optimisation of texture angle appears to be important for the best performance of the solar cells. An alternative way of reducing the surface reflection and enhancement of the cell parameters is to produce to passive front surface porous silicon layer. An analysis of the characteristics of a porous silicon layer shows that the morphology of the layer is an important design parameter. To realise the structures in practice, several methods are available, but many of this method are either not cost effective or commercially non available.In order to achieve good uniformity of pyramidal textured structure of the silicon surface, a mixture of NaOH/KOH and isopropyl alcohol (IPA) is generally used for texturization of mono crystalline solar cells. However, due to high cost of IPA, there is always search for alternative source. This source should not only be cost effective but should also result in reduced interfacial energy between silicon and ionised electrolyte chemical solution to achieve sufficient wet-ability for the silicon surface in order to enhance pyramid nucleation. Different novel texturization techniques for monocrystalline silicon are descried in this chapter including solar cells performance. For multicrystalline silicon (mc-Si) solar cells, the standard alkaline solution of NaOH/KOH does not produced textured surface of good quality so as to give satisfactory open circuit voltage and efficiency. This is because of grain boundary delineation with step formed between successive grains of different orientations. Different novel texturization techniques for multicrystalline silicon are also included in this book including solar cells performance. Reduction of optical losses in both mono and multicrystalline silicon solar cells by surface texturing is one of the important issues of modern silicon photovoltaics. This book discusses different novel texturization techniques for monocrystalline silicon including solar cells performance.

Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to Grand Eagle Retail, Bensenville, Illinois, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
